Diabetes Tests & Diagnosis
Your health care professional can diagnose diabetes, prediabetes, and gestational diabetes through blood tests. The blood tests show if your blood glucose, also called blood sugar, is too high. Do not try to diagnose yourself if you think you might have diabetes. Testing equipment that you can buy over the counter, such as a blood glucose meter, cannot diagnose diabetes. Who should be tested for diabetes? Anyone who has symptoms of diabetes should be tested for the disease. Some people will not have any symptoms but may have risk factors for diabetes and need to be tested. Testing allows health care professionals to find diabetes sooner and work with their patients to manage diabetes and prevent complications. Testing also allows health care professionals to find prediabetes. Making lifestyle changes to lose a modest amount of weight if you are overweight may help you delay or prevent type 2 diabetes. Type 1 diabetes Most often, testing for occurs in people with diabetes symptoms. Doctors usually diagnose type 1 diabetes in children and young adults. Because type 1 diabetes can run in families, a study called TrialNet offers free testing to family members of people with the disease, even if they don’t have symptoms. Type 2 diabetes Experts recommend routine testing for type 2 diabetes if you are age 45 or older are between the ages of 19 and 44, are overweight or obese, and have one or more other diabetes risk factors are a woman who had gestational diabetes1 Medicare covers the cost of diabetes tests for people with certain risk factors for diabetes. If you have Medicare, find out if you qualify for coverage . If you have different insurance, ask your insurance company if it covers diabetes tests. Though type 2 diabetes most often develops in adults, children also ca Continue reading >>
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 >>
Diabetes: What Are The Most Common Reasons Why Patients Don't Test Their Blood Glucose?
I respectfully disagree with some of what one poster has listed. Testing is absolutely necessary for *every* person with diabetes, regardless of what "type" they have. It's misinformation to be told otherwise, and one more reason why diabetes patients should see an endocrinologist or doctor who actually specializes in diabetes management, whenever possible. The only way anyone with diabetes knows what foods cause dangerous blood sugar spikes is by testing and using a before/after approach. Test before meals and two hours afterward. Standard goals would have you at a glucose reading of 120 or less after meals, and every diabetic should strive to stay below 140 at any given time. Above 140, diabetes is doing damage to your internal organs. Most people don't test because they fear needles or pain. If you are using your lancing device properly, it's not much more than an annoyance to prick your finger. The device should not be set to drive the lancet into your finger in a painful way. Find the level that works for you and your pain tolerance. I won't lie and say you won't feel anything, but it is not unbearable. There are also new lancing devices that allow you to test from areas other than your fingertips and those test areas are more like receiving a mosquito bite than a needle stick. The other reason people avoid testing is due to insurance reasons. Either insurance is completely lacking or the company only pays for a certain amount of lancets and test strips. This can be gotten over in a couple of ways. First, have your doctor write a prescription for lancets and strips that coincide with the actual amount of testing you feel necessary to maintain control of your disease. Second, have your doctor get a pre-approval from your insurance company to cover the greater amount Continue reading >>
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 >>

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 >>
Testing For Canine Diabetes
Introduction Canine diabetes mellitus is a chronic disorder of the endocrine system that occurs when the pancreas is unable to produce an adequate supply of insulin, or alternatively when a dog’s cells are unable to take up the insulin that is produced. If your dog is showing clinical signs that are suggestive of diabetes mellitus, your veterinarian will run a series of tests to confirm the diagnosis. Several other diseases can cause the same or similar symptoms as canine diabetes mellitus, so several tests are usually necessary to rule out other conditions and to confirm a definitive diagnosis of diabetes. Testing for Diabetes Mellitus in Dogs Your veterinarian will conduct a thorough physical examination to assess your dog’s general health. She probably will ask you about any changes in your dog’s behavior and body, such as increased or decreased urination, thirst or appetite, weight loss or lethargy, among other possible signs. Some tests are fairly standard in the assessment of diabetes. A urine sample will be collected and tested for the presence of glucose or bacteria in the urine. A bladder or urinary tract infection can mimic the clinical signs of diabetes, but also commonly accompanies the disease. Blood samples will be analyzed for a number of things, especially for the levels of blood glucose, cholesterol and liver enzymes. Your dog likely will need to fast for 12-24 hours before this particular blood test, to ensure accurate results. A single blood test may not be sufficient for a definitive diagnosis, so additional tests may be necessary. Some other things your veterinarian may recommend include abdominal ultrasound and assessment of serum thyroid hormone concentration, serum pancreatic enzyme levels, blood progersterone concentration in intact female Continue reading >>
Glucose Screening And Glucose Tolerance Tests
Why do I need a glucose screening test during pregnancy? Most healthcare practitioners routinely recommend a glucose screening test (also called a glucose challenge test or GCT) between 24 and 28 weeks of pregnancy to check for gestational diabetes. Gestational diabetes is a high blood sugar condition that some women get during pregnancy. Between 2 and 5 percent of expectant mothers develop this condition, making it one of the most common health problems during pregnancy. And because the condition rarely causes any symptoms, testing is the only way to find out whether you have it. Like any screening test, the GCT won't give you a diagnosis. Instead, it's designed to identify as many women as possible who may have a problem and need more testing to find out. So a positive result doesn't mean that you have gestational diabetes. In fact, only about a third of women who test positive on the glucose screen actually have the condition. If you test positive on the screening, you'll need to take the glucose tolerance test (GTT) – a longer, more definitive test that tells you for sure whether you have gestational diabetes. Your practitioner may want you to be screened earlier than 24 weeks if a routine urine test shows a lot of sugar in your urine or if you're considered high risk. If the results are normal, you'll be screened again at 24 to 28 weeks. Of course, if you were diagnosed with diabetes before pregnancy, you won't need to be screened. Instead, you'll continue to work with your practitioner to manage your condition during pregnancy. How is the glucose screening test done? When you arrive for the test, you're given a sugar solution that contains 50 grams of glucose. The stuff tastes like a very sweet soda pop (it comes in cola, orange, or lime flavor), and you have to Continue reading >>
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 >>
What Should Be The Frequency Of The Hba1c Test For Type 2 Diabetes Patients?
No more often than every three months. The effects of changes to diet or use of medicines won't be accurate if some of the glucose averages are retained from the time spans included before the last test and before treatment changes were considered to be altered. If at all possible, 4 months is best. The life span of the RBC is 120 days in our circulation. As the HgbA1c is a measure of accumulated glucose, it matters directly when the pool of RBCs is turned over. With good control (<7 or <6.5%) testing can be reduced to every 6 months. It's important to not get overly high average readings by testing in a smaller interval than 3 months. Those a1c readings are not fully new readings. There are tests being marketed here with a new twist. Glycomark may be a method to find the average glucose in the two week interval. Obvious applications for flexibility in changing treatment plans sooner, and reducing poor control of sugars are the first-glance benefits. Continue reading >>
Screening For Type 2 Diabetes
Diabetes is a disease in which the body does not produce or properly use insulin (the hormone that converts food into energy). There are several types of diabetes, the most common of which is type 2. In fact, about 95% of people with diabetes have type 2. Diabetes is a chronic disease that has no cure and can cause many serious complications such as eye disease, kidney failure, and nerve damage that can lead to amputation. Having diabetes significantly increases your risk of stroke and heart disease. Blood Glucose screening for Type 2 Diabetes A quick and easy finger-stick screening that measures blood sugar levels following eight hours of fasting, our Blood Glucose test helps identify diabetes —a major risk factor for heart disease and stroke — as well as monitor blood sugar levels for those already diagnosed with the disease. Who should have a Blood Glucose screening? Anyone who has risk factors for diabetes People aged 45 and over Adults with high blood pressure and high cholesterol levels How often should I get a Blood Glucose screening? People aged 45 and over should get screened every three years *Recommended guidelines only. Consult with your physician. How do I prepare for a Blood Glucose screening? You must fast (no food or drink, other than water) for 12 hours before your glucose screening. Warning signs Most people with type 2 diabetes live with it for years without realizing that they have it. Many learn they have diabetes only after it causes one of its complications, such as heart disease, stroke, eye damage, nerve damage, and kidney disease. However, these are symptoms some people experience: Frequent urination Unusual thirst Extreme hunger Unusual weight loss Extreme fatigue Irritability Frequent infections Blurred vision Cuts or bruises that are slo Continue reading >>
Are There Other Chronic Illnesses That Require Daily Tests Like Diabetes?
Actually, not all diabetics need to check their blood sugar three times a day. It depends on the severity of the illness and what medication they are taking for it. Yes, some do, but not all. Anyway to answer your question, I can think of two other chronic illnesses that could require a form of daily “testing.” One is hypertension. Not all people with high blood pressure need to check their BP on a daily basis, but many do need to do this. The other chronic illness that I can think of is heart failure. Many people with heart failure need to weigh themselves daily in order to make sure that they are not retaining fluid, which can cause a negative effect on the heart. I can’t think of any other examples. Hope this answers your question, though. Continue reading >>

5 Important Tests For Type 2 Diabetes
It takes more than just one abnormal blood test to diagnose diabetes.Istockphoto For centuries, diabetes testing mostly consisted of a physician dipping his pinkie into a urine sample and tasting it to pick up on abnormally high sugar. Thankfully, testing for type 2 diabetes is lot easier now—at least for doctors. Urine tests can still pick up diabetes. However, sugar levels need to be quite high (and diabetes more advanced) to be detected on a urine test, so this is not the test of choice for type 2 diabetes. Blood tests Almost all diabetes tests are now conducted on blood samples, which are collected in a visit to your physician or obstetrician (if you're pregnant). More about type 2 diabetes If you have an abnormal resultmeaning blood sugar is too high—on any of these tests, you'll need to have more testing. Many things can affect blood sugar (such as certain medications, illness, or stress). A diabetes diagnosis requires more than just one abnormal blood sugar result. The main types of diabetes blood tests include: Oral glucose-tolerance test. This test is most commonly performed during pregnancy. You typically have your blood drawn once, then drink a syrupy glucose solution and have your blood drawn at 30 to 60 minute intervals for up to three hours to see how your body is handling the glut of sugar. Normal result: Depends on how many grams of glucose are in the solution, which can vary. Fasting blood sugar. This is a common test because it's easy to perform. After fasting overnight, you have your blood drawn at an early morning doctor's visit and tested to see if your blood sugar is in the normal range. Normal result: 70-99 milligrams per deciliter (mg/dl) or less than 5.5 mmol/L Two-hour postprandial test. This blood test is done two hours after you have eate Continue reading >>
It's important for diabetes to be diagnosed early so treatment can be started as soon as possible. If you experience the symptoms of diabetes, visit your GP as soon as possible. They'll ask about your symptoms and may request blood and urine tests. Your urine sample will be tested for glucose. Urine doesn't normally contain glucose, but glucose can overflow through the kidneys and into your urine if you have diabetes. If your urine contains glucose, a specialised blood test known as glycated haemoglobin (HbA1c) can be used to determine whether you have diabetes. Glycated haemoglobin (HbA1c) In people who have been diagnosed with diabetes, the glycated haemoglobin (HbA1c) test is often used to show how well their diabetes is being controlled. The HbA1c test gives your average blood glucose levels over the previous two to three months. The results can indicate whether the measures you're taking to control your diabetes are working. If you've been diagnosed with diabetes, it's recommended you have your HbA1c measured at least twice a year. However, you may need to have your HbA1c measured more frequently if: you've recently been diagnosed with diabetes your blood glucose remains too high your treatment plan has been changed Unlike other tests, such as the glucose tolerance test (GTT), the HbA1c test can be carried out at any time of day and doesn't require any special preparation, such as fasting. However, the test can't be used in certain situations, such as during pregnancy. The advantages associated with the HbA1c test make it the preferred method of assessing how well blood glucose levels are being controlled in a person with diabetes. HbA1c can also be used as a diagnostic test for diabetes and as a screening test for people at high risk of diabetes. HbA1c as a diagno Continue reading >>

What Is The Medical Test For Diabetes?
Anyone with risks, family history and visible symptoms of diabetes or those who have already been diagnosed must get their sugar levels tested in order to ensure they are well informed of the condition. The following necessary tests will give a clear picture of how to monitor your blood sugar by keeping essential parameters in check. • Glycated Hemoglobin (HbA1C) test is the common test to know the average of your blood sugar levels over a period of the past three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells. 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. • Random blood sugar test is done through a blood sample anytime during the day when the patient is unable to be in a fasting state. A reading of 200 mg/dL or above suggests the person has diabetes. • Fasting blood sugar test is done after overnight fasting by the patient. A fasting blood sugar level from 100 to 125 mg/dL is considered pre-diabetes. Higher than 126 mg/dL is considered to be a diabetic condition. • Oral glucose tolerance test is carried out when the patient fasts overnight and is made to drink a sugary liquid the next day. Blood sugar levels are tested periodically for net two hours. Here the normal range and other readings differ in terms of – less than 140 mg/dL is considered normal whereas a reading of more than 200 mg/dL after two hours indicates diabetes. Medical tests for Diabetics also include tests of the eyes and feet. Continued high sugar levels cause tiny blood vessels inside our eyes to burst which destroys vision in the long run. Hence dilated eye exam will tell your heal Continue reading >>
