What Blood Test To Check For Diabetes?

Hba1c Test For Diabetes

Hba1c Test For Diabetes

Tweet The HbA1c test, also known as the haemoglobin A1c or glycated haemoglobin test, is an important blood test that gives a good indication of how well your diabetes is being controlled. Together with the fasting plasma glucose test, the HbA1c test is one of the main ways in which type 2 diabetes is diagnosed. HbA1c tests are not the primary diagnostic test for type 1 diabetes but may sometimes be used together with other tests. For HbA1c guidelines for monitoring diabetes control, see our HbA1c targets page. HbA1c testing in diagnosing diabetes The World Health Organisation (WHO) suggests the following diagnostic guidelines for diabetes: HbA1c below 42 mmol/mol (6.0%): Non-diabetic HbA1c between 42 and 47 mmol/mol (6.0–6.4%): Impaired glucose regulation (IGR) or Prediabetes HbA1c of 48 mmol/mol (6.5%) or over: Type 2 diabetes If your HbA1c test returns a reading of 6.0–6.4%, that indicates prediabetes. Your doctor should work with you to suggest appropriate lifestyle changes that could reduce your risk of developing type 2 diabetes. HbA1c is not used to diagnose gestational diabetes in the UK. Instead, an oral glucose tolerance test is used. A random blood glucose test will usually be used to diagnose type 1 diabetes. However, in some cases, an HbA1c test may be used to support a diagnosis of type 1 diabetes. People with diabetes who reduced their HbA1c by less than 1% can cut their risk of dying within 5 years by 50%, according to Swedish research presented at the annual meeting of the European Association for the Study of Diabetes, Sept. 2012 (EASD). How is HbA1c tested? To measure a person's HbA1c level, a blood sample is taken from the patient's arm, and used to produce a reading. In some cases, such as with HbA1c testing for children, a single droplet of blo Continue reading >>

Monitoring Your Blood Sugar Level

Monitoring Your Blood Sugar Level

What tests can I use to check my blood sugar level? There are 2 blood tests that can help you manage your diabetes. One of these tests is called an A1C test, which reflects your blood sugar (or blood glucose) control over the past 2-3 months. Testing your A1C level every 3 months is the best way for you and your doctor to understand how well your blood sugar levels are controlled. Your A1C goal will be determined by your doctor, but it is generally less than 7%. The other test is called SMBG, or self-monitoring of blood glucose. Using a blood glucose monitor to do SMBG testing can help you improve control of your blood sugar levels. The results you get from an SMBG test can help you make appropriate adjustments to your medicine, diet and/or level of physical activity. Every person who has diabetes should have a blood glucose monitor (also called a home blood sugar meter, a glucometer, or a glucose meter) and know how to use it. Your doctor may prescribe a blood glucose monitor. The U.S. Food and Drug Administration (FDA) has approved meters that work without pricking your finger. But these meters cannot replace regular glucose meters. They are used to get additional readings between regular testing. What supplies do I need? You will need a glucose meter, alcohol pads, sterile finger lancets and sterile test strips. Check with your health insurance plan to see if they will pay for these supplies. How do I pick a glucose meter? Check with your health insurance plan to see if they will pay for your glucose meter. If so, your plan may only pay for a certain meter. If your insurance plan doesn’t pay for glucose meters, ask your doctor which meters he or she recommends. Shop around and compare costs. Consider what features are important to you. For example, some meters are Continue reading >>

A Diabetes Test You Can Do Yourself

A Diabetes Test You Can Do Yourself

Are you urinating more often, feeling very thirsty, hungry, or tired? Maybe you’re losing weight. You may have type 2 diabetes. To find out, you can make an appointment with your doctor and have your blood tested for the condition. Or you can go to the drug store, buy a blood glucose meter, and give yourself a diabetes test. An estimated 40 percent of adults with type 2 diabetes don’t know they have it, which means they aren’t getting treatment that could protect them from very serious health problems down the road, such as heart disease, stroke, blindness, and kidney failure. The best option is to go to a doctor if you’re having symptoms of diabetes. But if you’re reluctant to do that, for whatever reason, the next best thing is to buy an over-the-counter diabetes test kit. "If you have a family history of diabetes, are obese, or have high blood pressure, you should test yourself for diabetes, if your doctor hasn’t already done so," says Marvin M. Lipman, M.D., Consumer Reports' chief medical adviser. "By being a proactive person, you might save yourself a lot of grief in the future.” Blood glucose meters can be purchased without a prescription. Models in our Ratings of more than two dozen devices cost $10 to $75. They usually come with 10 lancets, but you might have to buy a pack of test strips separately, which can cost $18 and up; check the package to see what it includes. If the meter doesn’t come with strips, make sure you buy a pack made for that model or you’ll get inaccurate results. Most models come with batteries. Here’s what you need to do next: Fast overnight. Don’t have anything to eat or drink (except water) for at least 8 hours, then test yourself first thing in the morning, before breakfast. Follow directions. Read the manual to ma Continue reading >>

Diabetics Can Now Test Their Blood Sugar Levels With A Mobile Device

Diabetics Can Now Test Their Blood Sugar Levels With A Mobile Device

People living with diabetes have to prick their fingers to check their blood sugar levels anywhere from one to seven times a day. But now, there’s a better way to monitor blood sugar. This week, the US Food and Drug Administration approved the first at-home, needleless system for continuously monitoring glucose for people with diabetes. The system, called FreeStyle Libre Flash, and manufactured by the DC-based Abbott Laboratories, allows users to forgo finger-pricking for up to 10 days at a time. The Flash is essentially a small, circular plastic sensor that sits on top of the skin and detects blood sugar from a small wire that goes under the skin beneath the sensor. People can insert themselves using an applicator that works sort of like a rubber stamp. Once people have applied the sensor on their arms, they can wave a mobile device a little smaller than a smartphone in front of it to read glucose levels. It takes about 12 hours for the wire to become adjusted to the person’s body, but afterward the device takes continuous data that tracks blood sugar over time for over a week. Afterward, you peel the sensor off slowly, and apply a new one. Ideally, this would encourage people with diabetes to check their blood sugar more routinely, Jared Watkin, senior vice president of Abbott’s Diabetes Care unit, told Reuters. Often, people will forgo checking their sugar levels as often as they should because finger pricking can be such a nuisance. Right now it’s only marketed for adults, but the company hopes to receive approval for children under 18 as well. Abbott already has one needle-free blood sugar monitoring system available for the public called the FreeStyle Libre Pro. However, users have to make a special trip to the doctor’s office to have the wire placed und Continue reading >>

What Tests To Expect

What Tests To Expect

Why is screening for diabetes important? People can have prediabetes or type 2 diabetes for years and not have any obvious signs or symptoms. Type 2 diabetes is often not diagnosed until health problems appear as a result of high blood glucose. These can include vision problems, kidney disease, or nerve damage. If left untreated, diabetes can cause more serious problems like blindness, kidney failure, leg amputation, heart attacks, and stroke. It’s important to know if you have prediabetes or diabetes, so you can make lifestyle changes or take medication to manage your condition. People at risk should be screened (tested) for diabetes and prediabetes. How do you get screened for diabetes? There are three blood tests that can be used to check the levels of glucose in your blood and diagnose prediabetes or diabetes: Fasting blood glucose test (FBG). Blood is drawn in the morning after you go without food overnight or for at least 8 hours. Oral glucose tolerance test (OGTT). This test is also done in the morning after going without food overnight or for at least 8 hours. Blood is drawn before you drink 8 ounces of a sugar solution and 2 hours after. This test is more precise but less convenient than the FBG test. Hemoglobin A1C test (A1C).This test shows what your average blood glucose levels have been over the past 2–3 months. You can eat and drink normally before the test. What is an A1C test? The A1C test is a blood test used to diagnose diabetes and to aid in its management. Current guidelines recommend an A1C level below 7 in healthy adults and below 7.5 in children with certain medical conditions.The test measures your average blood glucose over the past two to three months and shows how well your treatment plan is working overall. It does not take the place of d Continue reading >>

Testing

Testing

There are a range of tests which will need to be done to monitor your health and your diabetes. Some of these, such as your blood glucose levels, you will be able to do yourself. Others will be done by healthcare professionals. Self-monitoring of blood glucose can be a beneficial part of diabetes management. As part of the day-to-day routine it can help with necessary lifestyle and treatment choices as well as help to monitor for symptoms of hypo- or hyperglycaemia. Monitoring can also help you and your healthcare team to alter treatment which in turn can help prevent any long-term complications from developing. Some people with diabetes (but not all) will test their blood glucose levels at home. Home blood glucose testing gives an accurate picture of your blood glucose level at the time of the test. It involves pricking the side of your finger (as opposed to the pad) with a finger-pricking device and putting a drop of blood on a testing strip. Some people can't see the point of testing as they think they know by the way they feel, but the way you feel is not always a good or accurate guide to what is happening. Blood glucose targets It is important that the blood glucose levels being aimed for are as near normal as possible (that is in the range of those of a person who does not have diabetes). These are: 3.5–5.5mmol/l* before meals less than 8mmol/l, two hours after meals. There are many different opinions about the ideal range to aim for. As this is so individual to each person, the target levels must be agreed between the person and their diabetes team. The target blood glucose ranges below are indicated as a guide. Children with Type 1 diabetes (NICE 2015) on waking and before meals: 4–7mmol/l after meals: 5–9mmol/l.after meals: 5–9mmol/l. Adults with Type Continue reading >>

The A1c Test & Diabetes

The A1c Test & Diabetes

What is the A1C test? The A1C test is a blood test that provides information about a person’s average levels of blood glucose, also called blood sugar, over the past 3 months. The A1C test is sometimes called the hemoglobin A1c, HbA1c, or glycohemoglobin test. The A1C test is the primary test used for diabetes management and diabetes research. How does the A1C test work? The A1C test is based on the attachment of glucose to hemoglobin, the protein in red blood cells that carries oxygen. In the body, red blood cells are constantly forming and dying, but typically they live for about 3 months. Thus, the A1C test reflects the average of a person’s blood glucose levels over the past 3 months. The A1C test result is reported as a percentage. The higher the percentage, the higher a person’s blood glucose levels have been. A normal A1C level is below 5.7 percent. Can the A1C test be used to diagnose type 2 diabetes and prediabetes? Yes. In 2009, an international expert committee recommended the A1C test as one of the tests available to help diagnose type 2 diabetes and prediabetes.1 Previously, only the traditional blood glucose tests were used to diagnose diabetes and prediabetes. Because the A1C test does not require fasting and blood can be drawn for the test at any time of day, experts are hoping its convenience will allow more people to get tested—thus, decreasing the number of people with undiagnosed diabetes. However, some medical organizations continue to recommend using blood glucose tests for diagnosis. Why should a person be tested for diabetes? Testing is especially important because early in the disease diabetes has no symptoms. Although no test is perfect, the A1C and blood glucose tests are the best tools available to diagnose diabetes—a serious and li Continue reading >>

How Is Diabetes Diagnosed?

How Is Diabetes Diagnosed?

Out of the estimated 24 million people with diabetes, one third, or eight million, don’t know they have the disease. According to Martin J. Abrahamson, M.D., Medical Director and Senior Vice President at Joslin Diabetes Center, this is because people with type 2 diabetes often have no symptoms. However, a simple blood test is all you need to find out if you are one the millions with untreated diabetes. Who should be tested? The American Diabetes Association (ADA) recommends that everyone aged 45 and over should be tested for diabetes, and if the results are normal, re-tested every three years. Testing should be conducted at earlier ages and carried out more frequently in individuals who have any of the following diabetes risk factors: You have a parent or sibling with diabetes You are overweight (BMI higher than 25) You are a member of a high-risk ethnic population (African American, Hispanic American, Native American, Asian American or Pacific Islander) You had gestational diabetes or a baby weighing over 9 pounds Your HDL cholesterol levels are 35 mg/dl or less, and/or your triglyceride level is 250 mg/dl or above You have high blood pressure You have polycystic ovarian syndrome On previous testing, had impaired glucose tolerance or impaired fasting tolerance What tests are used for diagnosis? Fasting Plasma Glucose –This blood test is taken in the morning, on an empty stomach. A level of 126 mg/dl or above, on more than one occasion, indicates diabetes. Casual or Random Glucose - This blood test can be taken anytime during the day, without fasting. A glucose level of 200 mg/dl and above may suggest diabetes. If any of these test results occurs, testing should be repeated on a different day to confirm the diagnosis. If a casual plasma glucose equal to 200 mg/dl or Continue reading >>

Diagnosing Diabetes

Diagnosing Diabetes

In diagnosing diabetes, physicians primarily depend upon the results of specific glucose tests. However, test results are just part of the information that goes into the diagnosis of type 1 or type 2 diabetes. Doctors also take into account your physical exam, presence or absence of symptoms, and medical history. Some people who are significantly ill will have transient problems with elevated blood sugars, which will then return to normal after the illness has resolved. Also, some medications may alter your blood glucose levels (most commonly steroids and certain diuretics, such as water pills). The 2 main tests used to measure the presence of blood sugar problems are the direct measurement of glucose levels in the blood during an overnight fast and measurement of the body's ability to appropriately handle the excess sugar presented after drinking a high glucose drink. Fasting Blood Glucose (Blood Sugar) Level A value above 126 mg/dL on at least 2 occasions typically means a person has diabetes. The Oral Glucose Tolerance Test An oral glucose tolerance test is one that can be performed in a doctor's office or a lab. The person being tested starts the test in a fasting state (having no food or drink except water for at least 10 hours but not greater than 16 hours). An initial blood sugar is drawn and then the person is given a "glucola" bottle with a high amount of sugar in it (75 grams of glucose or 100 grams for pregnant women). The person then has their blood tested again 30 minutes, 1 hour, 2 hours, and 3 hours after drinking the high glucose drink. For the test to give reliable results, you must be in good health (not have any other illnesses, not even a cold). Also, you should be normally active (for example, not lying down or confined to a bed like a patient in a Continue reading >>

Diagnosis

Diagnosis

Print Symptoms of type 1 diabetes often appear suddenly and are often the reason for checking blood sugar levels. Because symptoms of other types of diabetes and prediabetes come on more gradually or may not be evident, the American Diabetes Association (ADA) has recommended screening guidelines. The ADA recommends that the following people be screened for diabetes: Anyone with a body mass index higher than 25, regardless of age, who has additional risk factors, such as high blood pressure, a sedentary lifestyle, a history of polycystic ovary syndrome, having delivered a baby who weighed more than 9 pounds, a history of diabetes in pregnancy, high cholesterol levels, a history of heart disease, and having a close relative with diabetes. Anyone older than age 45 is advised to receive an initial blood sugar screening, and then, if the results are normal, to be screened every three years thereafter. Tests for type 1 and type 2 diabetes and prediabetes Glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal. If the A1C test results aren't consistent, the test isn't available, or if you have certain conditions that can make the A1C test inaccurate — such as if you're pregnant or have an uncommon form of hemoglobin (known as a hemoglobin variant) — your doctor may use the following tests to diagnose diabetes: Random blood sugar Continue reading >>

Symptoms, Diagnosis & Monitoring Of Diabetes

Symptoms, Diagnosis & Monitoring Of Diabetes

According to the latest American Heart Association's Heart Disease and Stroke Statistics, about 8 million people 18 years and older in the United States have type 2 diabetes and do not know it. Often type 1 diabetes remains undiagnosed until symptoms become severe and hospitalization is required. Left untreated, diabetes can cause a number of health complications. That's why it's so important to both know what warning signs to look for and to see a health care provider regularly for routine wellness screenings. Symptoms In incidences of prediabetes, there are no symptoms. People may not be aware that they have type 1 or type 2 diabetes because they have no symptoms or because the symptoms are so mild that they go unnoticed for quite some time. However, some individuals do experience warning signs, so it's important to be familiar with them. Prediabetes Type 1 Diabetes Type 2 Diabetes No symptoms Increased or extreme thirst Increased thirst Increased appetite Increased appetite Increased fatigue Fatigue Increased or frequent urination Increased urination, especially at night Unusual weight loss Weight loss Blurred vision Blurred vision Fruity odor or breath Sores that do not heal In some cases, no symptoms In some cases, no symptoms If you have any of these symptoms, see your health care provider right away. Diabetes can only be diagnosed by your healthcare provider. Who should be tested for prediabetes and diabetes? The U.S. Department of Health and Human Services recommends that you should be tested if you are: If your blood glucose levels are in normal range, testing should be done about every three years. If you have prediabetes, you should be checked for diabetes every one to two years after diagnosis. Tests for Diagnosing Prediabetes and Diabetes There are three ty Continue reading >>

What Is A Blood Test?

What Is A Blood Test?

A blood test is when a sample of blood is taken from the body to be tested in a lab. Doctors order blood tests to check things such as the levels of glucose, hemoglobin, or white blood cells. This can help them detect problems like a disease or medical condition. Sometimes, blood tests can help them see how well an organ (such as the liver or kidneys) is working. What Is a Glucose Test? A glucose test measures how much glucose is in the blood. Glucose is a type of sugar used by the body for energy. Why Are Glucose Tests Done? A glucose test is done to check for low or high levels of glucose. Sometimes it's done as part of a routine checkup to screen for problems, and sometimes because a child has not been feeling well. A low glucose level is called hypoglycemia. A high level of glucose is called hyperglycemia. High glucose levels can point to diabetes. How Should We Prepare for a Glucose Test? Your child may be asked to stop eating and drinking for 8 to 12 hours before the test. Tell your doctor about any medicines your child takes because some drugs might affect the test results. Wearing a T-shirt or short-sleeved shirt for the test can make things easier for your child, and you also can bring along a toy or book as a distraction. How Is a Glucose Test Done? Most blood tests take a small amount of blood from a vein. To do that, a health professional will: clean the skin put an elastic band (tourniquet) above the area to get the veins to swell with blood insert a needle into a vein (usually in the arm inside of the elbow or on the back of the hand) pull the blood sample into a vial or syringe take off the elastic band and remove the needle from the vein In babies, blood draws are sometimes done as a "heel stick collection." After cleaning the area, the health profession Continue reading >>

Getting Tested

Getting Tested

You’ll need to get your blood sugar tested to find out for sure if you have prediabetes or type 1, type 2, or gestational diabetes. Testing is simple, and results are usually available quickly. Type 1 Diabetes, Type 2 Diabetes, and Prediabetes Your doctor will have you take one or more of the following blood tests to confirm the diagnosis: A1C Test This measures your average blood sugar level over the past 2 or 3 months. An A1C below 5.7% is normal, between 5.7 and 6.4% indicates you have prediabetes, and 6.5% or higher indicates you have diabetes. Fasting Blood Sugar Test This measures your blood sugar after an overnight fast (not eating). A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes. Glucose Tolerance Test This measures your blood sugar before and after you drink a liquid that contains glucose. You’ll fast (not eat) overnight before the test and have your blood drawn to determine your fasting blood sugar level. Then you’ll drink the liquid and have your blood sugar level checked 1 hour, 2 hours, and possibly 3 hours afterward. At 2 hours, a blood sugar level of 140 mg/dL or lower is considered normal, 140 to 199 mg/dL indicates you have prediabetes, and 200 mg/dL or higher indicates you have diabetes. Random Blood Sugar Test This measures your blood sugar at the time you’re tested. You can take this test at any time and don’t need to fast (not eat) first. A blood sugar level of 200 mg/dL or higher indicates you have diabetes. Result* A1C Test Fasting Blood Sugar Test Glucose Tolerance Test Random Blood Sugar Test Normal Below 5.7% 99 mg/dL or below 140 mg/dL or below Prediabetes 5.7 – 6.4% 100 – 125 mg/dL 140 – 199 mg/dL Diabetes 6.5% or Continue reading >>

Preparing For Diabetes Labs And Other Tests

Preparing For Diabetes Labs And Other Tests

When people take insulin or diabetes pills to control blood sugar, it might take some extra planning before getting lab work and other tests done. Many tests, such as a blood test to measure cholesterol, require that a person stop eating, drinking, and taking medicine for a certain amount of time before the test. Tests can also be stressful for people. Stress can cause blood sugar levels to go up. When that happens, a person needs to test blood sugar levels more often and adjust medicine as needed. If you're worried about any tests that you have scheduled, even if the test isn't related to diabetes, talk to your doctor or other member of your health care team. Ask if you need to do anything special to prepare and whether the test might affect your blood sugar levels. Preparing for Tests Tests that require you to be at the medical facility for several hours Some tests require you to be at the medical facility for several hours. Even if you don't need to make any changes in what you eat or drink, tell the people in charge of the testing that you have diabetes. Ask if there are any special steps you need to take to make sure you can keep your blood sugar levels stable. A week or so before the test, make sure you know: What time you'll be having your test. How the test fits with your schedule for eating and taking your diabetes medicines. When your diabetes medicine is likely to reach its peak. If it's during the test, find out if you will be able to eat or drink something right before or right after the test to keep your blood sugar from dropping too low. On the day of your test: Take glucose tablets or a carbohydrate snack and your diabetes medicine with you to the test. Remind the people doing the test that you have diabetes. Tell them when you last ate and, if you take Continue reading >>
