Ultimate Guide To The A1c Test: Everything You Need To Know
The A1C is a blood test that gives us an estimated average of what your blood sugar has been over the past 2-3 months. The A1c goes by several different names, such aswa Hemoglobin A1C, HbA1C, Hb1C, A1C, glycated hemoglobin, glycohemoglobin and estimated glucose average. What is Hemoglobin? Hemoglobin is a protein in your blood cells that carries oxygen. When sugar is in the blood, and it hangs around for a while, it starts to attach to the red blood cells. The A1C test is a measurement of how many red blood cells have sugar attached. So, if your A1C result is 7%, that means that 7% of your red blood cells have sugar attached to them. What are the Symptoms of a High A1C Test Level? Sometimes there are NO symptoms! That is probably one of the scariest things about diabetes, your sugar can be high for a while and you may not even know it. When your blood sugar goes high and stays high for longer periods of time you may notice the following: tired, low energy, particularly after meals feel very thirsty you may be peeing more than normal, waking a lot in the middle of the night to go dry, itchy skin unexplained weight loss crave sugar, hungrier than normal blurred vision, may feel like you need new glasses tingling in feet or hands cuts or sores take a long time to heal or don’t heal well at all frequent infections (urinary tract, yeast infections, etc.) When your blood sugar is high, this means the energy that you are giving your body isn’t getting into the cells. Think about a car that has a gas leak. You put gas in, but if the gas can’t get to the engine, the car will not go. When you eat, some of the food is broken down into sugar and goes into your bloodstream. If your body can’t get the sugar to the cells, then your body can’t “go.” Some of the sugar tha Continue reading >>
Blood Sugar Converter
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. Convert blood sugar/glucose from mmol/L (EU standard) to mg/dl (USA standard) and vice versa using our blood sugar converter. Keywords: blood sugar, blood sugar levels, mmol/l, mg/dl, convert blood glucose value How to use blood sugar converter tool? The use is very simple. This tool will convert mg/dl unit to mmol/l or convert mmol/l to mg/dl.. In the United States of America, blood glucose test (blood sugar test) results are reported as mg/dL. Medical journals and other countries use millimoles per liter (mmol/L). How to convert your value? First, select conversion mode. Either select mg/dl to mmol/l or mmol/l to mg/dl. Input your value (do not include “mg/dl” or “mmol/l”) and press calculate. Result will be displayed below. Low, normal and high blood sugar/glucose levels can be found in the table below. Expected blood sugar level values Blood Sugar Level Children mg/dl (mmol/l) Adults mg/dl (mmol/l) Normal 70 – 100 mg/dL (3.9 – 5.5 mmol/l) 70 – 140 mg/dL (3.9 – 7.7 mmol/l) Low lower than 70 mg/dL (lower than 3.9 mmol/l) lower than 70 mg/dL (lower than 3.9 mmol/l) High Over 140 mg/dL (over 7.7 mmol/l) Over 180 mg/dL (over 10 mmol/l) Blood sugar level values are a bit different because of unit conversions – from mg/dl to mmol/l. If you found yourself to have high blood sugar levels – you can lower your BS by maintaining normal body weight, eating healthy and by physical activity. For more information on blood sugar refer to this article on blood sugar levels. Continue reading >>

Hba1c In Early Diabetic Pregnancy And Pregnancy Outcomes
A Danish population-based cohort study of 573 pregnancies in women with type 1 diabetes Abstract OBJECTIVE—To assess the association between first-trimester HbA1c (A1C) and the risk of adverse pregnancy outcomes in type 1 diabetic pregnancies. RESEARCH DESIGN AND METHODS—We identified all pregnant diabetic women in a Danish county from 1985 to 2003. A1C values from first trimester were collected, and pregnancy outcome was dichotomized as good (i.e., babies surviving the 1st month of life without major congenital abnormalities) and adverse (i.e., spontaneous and therapeutic abortion, stillbirth, neonatal death, or major congenital abnormalities detected within the 1st month). The prevalence of adverse outcomes was calculated according to quintiles of A1C. We computed receiver operating characteristic and lowess curve estimates and fitted logistic regression models to calculate prevalence odds ratio while adjusting for confounding by White class and smoking status. RESULTS—Of 573 pregnancies, 165 (29%) terminated with adverse outcomes. The prevalence of adverse outcomes varied sixfold from 12% (95% CI 7.2–17) in the lowest to 79% (60–91) in the highest quintile of A1C exposure. From A1C levels >7%, we found an almost linear association between A1C and risk of adverse outcome, whereby a 1% increase in A1C corresponded to 5.5% (3.8–7.3) increased risk of adverse outcome. CONCLUSIONS—Starting from a first-trimester A1C level slightly <7%, there is a dose-dependent association between A1C and the risk of adverse pregnancy outcome without indication of a plateau, below which the association no longer exits. A1C, however, seems to be of limited value in predicting outcome in the individual pregnancy. Elevated HbA1c (A1C) is associated with increased risk of advers Continue reading >>
What Is The A1c Test? How Does A1c Relate To Blood Glucose?
Anyone with diabetes will be familiar with finger-prick testing for monitoring blood glucose to see how well they are managing their disease. This kind of regular testing is essential for most people with diabetes, but what role does an occasional hemoglobin A1C blood test play in controlling blood sugars, and how does it work? Contents of this article: What is the A1C test? The abbreviation A1C is used in the US (sometimes with a lower-case 'c' - A1c) and is short for glycated hemoglobin (sometimes called 'glycosylated' hemoglobin or glycohemoglobin). The other abbreviations in use are: HbA1c (widely used internationally) HbA1c Hb1c HgbA1C. The A1C test is a blood test used to measure the average level of glucose in the blood over the last two to three months. This test is used to check how well blood sugar levels are being controlled in a person with diabetes and can also be used in the diagnosis of diabetes.1 Hemoglobin is the protein in red blood cells which is responsible for transporting oxygen around the body. When blood glucose levels are elevated, some of the glucose binds to hemoglobin and, as red blood cells typically have a lifespan of 120 days, A1C (glycated hemoglobin) is a useful test because it offers an indication of longer term blood glucose levels.2 The particular type of hemoglobin that glucose attaches to is hemoglobin A, and the combined result is call glycated hemoglobin. As blood glucose levels rise, more glycated hemoglobin forms, and it persists for the lifespan of red blood cells, about four months.2 Therefore, the A1C level directly correlates to the average blood glucose level over the previous 8-12 weeks; A1C is a reliable test that has been refined and standardized using clinical trial data.3 There are two key things to know about the appl Continue reading >>

Translating A1c To A Blood Sugar Level
In the USA, doctors recommend that you have your Hemoglobin A1c measured at least twice per year. This simple blood test will tell you an approximation of your blood sugar control for the past 3 months based on the amount of Advanced Glycogenated End-Products (AGEs) that have accumulated in your blood. The higher your blood sugar levels are, the more AGEs are present. AGEs are also responsible for the development of complications such as retinopathy and neuropathy, because that accumulation will build and irritate crucial nerve-endings. Now, let’s get back to your A1C: To help people with diabetes understanding their A1C in real day-to-day terms, the medical world has developed the “eAG” measurement. Estimated Average Glucose. Your eAG will give your A1C reading in a blood sugar level of milligrams per deciliter (mg/dL) just like you’re used to seeing on your glucose meter. The American Diabetes Association has this easy calculator, allowing you to enter and translate your latest A1C to your eAG. 12% = 298 mg/dL (240 – 347) 11% = 269 mg/dL (217 – 314) 10% = 240 mg/dL (193 – 282) 9% = 212 mg/dL (170 –249) 8% = 183 mg/dL (147 – 217) 7% = 154 mg/dL (123 – 185) 6% = 126 mg/dL (100 – 152) What can you do with that information? It is recommended that people with type 1 and type 2 diabetes achieve an A1C of 7.0 percent or lower for optimal health, and the prevention of complications. This translates to an average blood sugar before and between meals around 70 to 130 mg/dL. And after meals, under 180 mg/dL. For pregnancy with diabetes, an A1C lower than 6.5 percent is imperative for the healthy development of your baby, and your own health and safety. Post-meal blood sugars for pregnant women is suggested at lower than 120 mg/dL. A non-diabetic’s A1C is Continue reading >>
Average blood glucose and the A1C test Your A1C test result (also known as HbA1c or glycated hemoglobin) can be a good general gauge of your diabetes control, because it provides an average blood glucose level over the past few months. Unlike daily blood glucose test results, which are reported as mg/dL, A1C is reported as a percentage. This can make it difficult to understand the relationship between the two. For example, if you check blood glucose 100 times in a month, and your average result is 190 mg/dL this would lead to an A1C of approximately 8.2%, which is above the target of 7% or lower recommended by the American Diabetes Association (ADA) for many adults who are not pregnant. For some people, a tighter goal of 6.5% may be appropriate, and for others, a less stringent goal such as 8% may be better.1 Talk to your doctor about the right goal for you.

On A Personal Note: How To Interpret Simple Blood Tests
In an earlier post we talked about eight simple blood tests that you should have done to help you keep track of your health. I recently had my yearly check-up at my primary care physciacns office so I thought I’d share my lab results and how to read simple blood tests. How To Read Blood Tests When I wrote about eight simple blood tests that people should have there are three that come to mind that I like to have done on a yearly basis: a lipid panel, a complete metabolic panel (CMP), and a compelte blood count (CMP). A simple lipid panel will tell you if your cholesterol is something you should be worried about, a CMP gives you some insight on your electrolyte levels, liver function, and kidney function. Lastly, a CBC can tell you if you have anything that might hint that you could have cancer, anemia, or some sort of crazy infection going on. Luckily, everything on my tests came back okay (heck I’m only 31), but I figure I could explain the blood tests in detail so some people have some insight as to what blood tests results could mean if they’re taking a look at their results for themselves. The BMP takes a look at a few different things inside of your body and can give you some pretty good insight into how things are functioning over all. Let’s break it down. Kidney Function: Test Name Result Range Blood Urea Nitrogen 25 mg/dl 7-25 Creatinine 0.95 mg/dl 0.60-1.35 GFR 106 > or = to 60 The GFR is the rate at which your kidneys filter your blood. If your rate starts dropping below 60, it’s not a good thing. A BUN and Creatinine can also indicate poor kidney function if levels are abnormal. But it can also indicate other things like dehydration. Elevated creatinine levels can also be related to rhabdomyolosis (rapid muscle breakdown) from either malnutrition or Continue reading >>
The Normal A1c Level
Wow Richard, 70 lbs? I have lost 24 lbs from low carb diet due to SIBO. It also helped my AC1 go down three points from 6.2 and my cholesterol is lower, which surprised me. I can’t afford to lose anymore weight because I was small to begin with. I had noticed much bigger people in the UK over the last 5 years compared to 15-20. Was quite shocking. I thought we had the patent on obesity! I am not diabetic that I know of but I had weird symptoms… Thirst that continued all day and night. My husband called me a camel. Dry eyes, rashes, strange dark discolouration on arm, under the arm to the side, some circulation issues and blurred vision. Eye specialist could not figure out why. Sores in the mouth also. I had observed about three weeks into super low carbs (30 Gms carb/day) that athlete’s foot symptom, sores in mouth and rashes were clearing up. So, lowering carbs for SIBO actually turned out for the best. By the way, I love your final paragraph. Research is what led me to SIBO diagnosis, and I then told the GI what to look for! He was barking up the wrong tree for months. Said I needed to eat more carbs so I don’t lose weight. Well, carbs fed the bacterial overgrowth!!! Dang fool.

Why Raise Your A1c?
Have you been ordered by your doctor to get your A1C (HbA1c) level up? More people are having this confusing experience, as doctors try to implement the 2013 ADA treatment guidelines. Do these orders make sense? Not much, I’d say. What is happening here? In 2012, the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) changed the targets doctors should aim for in treating diabetes. They went from a one-size-fits-all target of 7.0% HbA1c to a three-tiered guideline. HbA1c is the test that gives an idea of the average blood glucose level for the previous two months or so. An A1C of 7.0% equals an average blood glucose of around 154 mg/dl, and many people think that number is too high to protect against complications. So there was pressure to lower the guideline. At the same time, many older people found the 7.0% goal too strict. A few studies found an increased risk of falls in older people who run low glucose levels. There was concern about increased risk of hypoglycemia (low blood glucose). As Diane Fennell wrote here, many think that aiming for lower A1C levels leads to an increase in low blood glucose episodes. As many readers commented, hypos are dangerous and unpleasant. For many, they are the worst fact of life with diabetes. So the experts finally recognized that one size does not fit all. Unfortunately, their new guidelines have been misunderstood by some doctors, leading to people being told to raise their A1C numbers, even if doing so increases their complication risk. According to the new guidelines, older or sicker people, or those with many hypoglycemic episodes, might shoot for 7.5% to 8.0%. Younger, healthier, people might want to get their A1C below 6.5%, or even lower. People in between on age and health mi Continue reading >>
Sugar High Sugar Low: Preparing For Pregnancy
Before conceiving I had a lot of things to contemplate such as being fit, healthy, eating well, having tight control of my blood glucose levels and most important of all achieving at least an A1c of 7.0%. Both diabetes and pregnancy combined have their own unique challenges. I knew that I would have a lot of hard work ahead of me. My diabetes appointments are usually quarterly at the diabetic centre. My previous appointment showed that my A1c was 7.5%, so I decided to visit my diabetic team and inform them of my plan, as I did with my first pregnancy. The diabetic nurse retested my A1c and after two weeks I found out my A1C was actually 7.3%. Blood glucose control is vital during pregnancy because if you can imagine even before you’re aware of your pregnancy, your baby’s brain, spinal cord, heart and other organs have already started to form. This totally freaks me out because without tight control I could have possibly affected the way in which my child developed. I was given the opportunity to have a trial run of the dexcom G4 sensor for a month which I talked about in my post, “Cyborg for a month or perhaps longer”. Dexcom G4 – is a continuous glucose monitoring (CGM) sensor which is inserted into the body and is able to give blood glucose readings every five minutes. The sensor automatically transmits this reading to my insulin pump (Animas Vibe) and creates a graph. With my insulin pump I am able to set an ideal blood glucose range. If my blood glucose level goes above or below this range my insulin pump alarms to alert me of either an increase or decrease in blood glucose level. My trial run actually went on for longer than a month and it was during that time that I conceived. My pregnancy journey had started and with my team we made the decision to cont Continue reading >>
What Is A Good Score On The A1c Diabetes Test?
Normal A1C level can range from 4.5 to 6 percent. Someone who's had uncontrolled diabetes for a long time can have an A1C level above 9 percent. A1C test is used to diagnose diabetes, an A1C level of 6.5 percent or higher on two separate dates indicates diabetes. A result between 5.7 and 6.4 percent is considered prediabetes, which is high risk of developing diabetes. For most people who have previously diagnosed diabetes, an A1C level of 7 percent or less is a common treatment target. Higher targets may be chosen in some individuals. If your A1C level is above your target, your doctor may recommend a change in your diabetes treatment plan. Remember, the higher your A1C level, the higher your risk of diabetes complications. A good score on the A1C test depends on whether you’ve been diagnosed with diabetes. For those who do not have diabetes, a score of less than 5.7% is considered normal, while 5.7% to 6.4% indicates prediabetes and 6.5% or higher means you have diabetes. If you already have diabetes, a score of 7% or lower is desired. You and your doctor can decide what score is best for you. The A1C diabetes test is a way to get an average of how well your blood sugar has been controlled for the past three months. The standard A1C goal for most people with diabetes is less than 7%. However, the goal may be individualized or may be different for some people, especially older adults, people with heart disease or those who are prone to frequent low blood glucose. It's a good idea to find out what your A1C goal should be from your healthcare provider and then use that as a benchmark for your A1C results. No one quite agrees on where your A1C score should be, but we all agree on where it shouldn’t be. The scale does not look anything like the BGL numbers you are used Continue reading >>

PubMed Simonis-Bik, Annemarie M C; Eekhoff, Elisabeth M W; Diamant, Michaela; Boomsma, Dorret I; Heine, Rob J; Dekker, Jacqueline M; Willemsen, Gonneke; van Leeuwen, Marieke; de Geus, Eco J C In an extended twin study we estimated the heritability of fasting HbA1c and blood glucose levels. Blood glucose was assessed in different settings (at home and in the clinic). We tested whether the genetic factors influencing fasting blood glucose levels overlapped with those influencing HbA1c and whether the same genetic factors were expressed across different settings. Fasting blood glucose was measured at home and during two visits to the clinic in 77 healthy families with same-sex twins and siblings, aged 20 to 45 years. HbA1c was measured during the first clinic visit. A 4-variate genetic structural equation model was used that estimated the heritability of each trait and the genetic correlations among traits. Heritability explained 75% of the variance in HbA1c. The heritability of fasting blood glucose was estimated at 66% at home and lower in the clinic (57% and 38%). Fasting blood glucose levels were significantly correlated across settings (0.34 < r < 0.54), mostly due to a common set of genes that explained between 53% and 95% of these correlations. Correlations between HbA1c and fasting blood glucoses were low (0.11 < r < 0.23) and genetic factors influencing HbA1c and fasting glucose were uncorrelated. These results suggest that in healthy adults the genes influencing HbA1c and fasting blood glucose reflect different aspects of the glucose metabolism. As a consequence these two glycemic parameters can not be used interchangeably in diagnostic procedures or in studies attempting to find genes for diabetes. Both contribute unique (genetic) information. Hosking, Joanne; M Continue reading >>
The Abcs Of Diabetes: A1c, Blood Pressure, And Cholesterol
Three important diabetes measures There is so much to think about when you have diabetes, but this easy-to-remember acronym will help you focus on what’s important and take control of your health. Read our breakdown and talk to your doctor about what’s right for you. A = AIC What is it? An A1C blood test measures the percentage of hemoglobin (the oxygen-carrying protein in your red blood cells) coated with sugar. It measures your average blood glucose (sugar) level over the past two to three months. The A1C test gives you and your health care provider a measure of your progress. Most people with diabetes should have an A1C test every three to six months; people who are meeting their treatment goals may need the test only twice a year. Why is it important? The A1C test is a good measure of how well your glucose is under control. It can also be a good tool for determining if someone with prediabetes is progressing toward or has developed type 2 diabetes. Adults over age 45 with hypertension, obesity, or a family history of diabetes also are advised to get an A1C test because they have a greater risk of developing type 2 diabetes. Finding out you have an elevated A1C is a cue to make positive changes to your lifestyle. What do the numbers mean? 5.7% or lower = normal blood glucose levels 5.8–6.4% = elevated blood glucose levels (prediabetes) 6.5% or higher = diabetes What should my numbers be? For years, people with type 2 were told to strive for an A1C of 7 percent or less, but new research indicates that one level doesn’t fit all. Based on your health status, age, and risk factors, you and your health care provider should determine an A1C goal for you. Here are the American Diabetes Association’s new general guidelines: Person newly diagnosed with type 2 diabet Continue reading >>
