A1c Conversion Chart

Hemoglobin A1c Test

Overview: By Doris Dickson for Body1 A hemoglobin A1C test is primarily used to measure average glucose over prolonged periods of time. The test measures the build up of glycated hemoglobin within the red blood cells. This measurement reflects the average level of glucose the cell has been exposed during its life cycle which is approximately 10-12 weeks. Detailed Information: What is a Hemoglobin A1C (HbA1c)? Contrary to what many people believe, the test is not an average of your blood sugar as reflected on a home glucose monitor. Those tests are moments in time measured a number of times per day. Thus, an A1C is considered to be proportional to average blood glucose over the same period of time. This is reflective of the amount of sugar that sticks to the red blood cells 24 hours per day. Because of the life cycle of the red blood cells, it is recommended that diabetics have this test every three months. You might consider choosing one lab and staying with it, since laboratory results may differ depending on the analytical technique. Therefore, it is easier to adjust your diabetes care if you are comparing apples to apples. An example of an A1C conversion chart: There are many conversion tables available. The charts show a correlation from an A1c to an average blood sugar level. The chart below is based on the conversion formula of Dr. Richard Bernstein. There are several answers to this question and the experts do not seem to agree. According to Dr. Richard Bernstein a normal, healthy, thin, non-diabetic A1C will be within the range of 4.2-4.6. He also believes every diabetic can and should target, attain and sustain these normal levels. The American Diabetes Association (ADA) states an A1C of less than 6.0 is normal and recommends an A1C less than 7.0 in diabetics. Continue reading >>

A1c Test And Units Conversion

A1c Test The A1C test is a blood test that used to diagnose type 1 and type 2 diabetes. It is used gauge how well you’re managing your diabetes. The A1C test is also known as glycosylated hemoglobin, hemoglobin A1C, glycated hemoglobin and also HbA1c. The A1C test result is used as an representative indication of your average blood sugar level for the past two to three months. The A1C test is specifically used to measure what percentage of the hemoglobin (protein) in the red blood cells carries oxygen and is coated with sugar (glycated). A higher A1C level indicates poor blood sugar control and a higher risk of developing diabetes complications. A1c Test Units Some countries, such as the UK, Australia and New Zealand, use a different set of units for measuring A1c results. The way A1c values are reported in the US, using %, is known as the DCCT (Diabetes Control and Complications Trial) units. The way A1c is reported in some other countries is using the IFCC (International Federation of Clinical Chemistry) units. The IFCC values use mmol/mol (millimoles per mole). If you need to convert an A1c result from % to mmol/mol, or vice versa, use the calculator below. It will also give you the conversaion into mg/dl to compare it with your blood glucose readings and eAG results. A1c Units Converter Type 2 diabetes is a metabolic disorder that is characterized by high levels of glucose in the bloodstream which leads to hyperglycemia if untreated. It is strongly linked to obesity and unhealthy lifestyle habits such as lack of physical activity, poor diet and smoking. How common is type 2 diabetes? Type 2 diabetes is by far the most common form of diabetes mellitus, accounting for roughly 90% of all cases of diabetes. It affects an estimated 330 million people worldwide, includi Continue reading >>

Translating The A1c Assay Into Estimated Average Glucose Values

Go to: Abstract The A1C assay, expressed as the percent of hemoglobin that is glycated, measures chronic glycemia and is widely used to judge the adequacy of diabetes treatment and adjust therapy. Day-to-day management is guided by self-monitoring of capillary glucose concentrations (milligrams per deciliter or millimoles per liter). We sought to define the mathematical relationship between A1C and average glucose (AG) levels and determine whether A1C could be expressed and reported as AG in the same units as used in self-monitoring. A total of 507 subjects, including 268 patients with type 1 diabetes, 159 with type 2 diabetes, and 80 nondiabetic subjects from 10 international centers, was included in the analyses. A1C levels obtained at the end of 3 months and measured in a central laboratory were compared with the AG levels during the previous 3 months. AG was calculated by combining weighted results from at least 2 days of continuous glucose monitoring performed four times, with seven-point daily self-monitoring of capillary (fingerstick) glucose performed at least 3 days per week. Approximately 2,700 glucose values were obtained by each subject during 3 months. Linear regression analysis between the A1C and AG values provided the tightest correlations (AGmg/dl = 28.7 × A1C − 46.7, R2 = 0.84, P < 0.0001), allowing calculation of an estimated average glucose (eAG) for A1C values. The linear regression equations did not differ significantly across subgroups based on age, sex, diabetes type, race/ethnicity, or smoking status. A1C levels can be expressed as eAG for most patients with type 1 and type 2 diabetes. mg/dl* mmol/l† A1C (%) 5 97 (76–120) 5.4 (4.2–6.7) 6 126 (100–152) 7.0 (5.5–8.5) 7 154 (123–185) 8.6 (6.8–10.3) 8 183 (147–217) 10.2 (8.1–12.

Why The A1c Test Is Important

The A1c is a blood test, done in a lab, that shows what your average blood sugar has been for the past 3 months. Other names for this test are glycosylated hemoglobin, glycohemoglobin, hemoglobin A1c, and HbA1c. How the A1c Test Works The glucose that the body doesn't store or use for energy stays in the blood and attaches to red blood cells, which live in the bloodstream for about 4 months. The lab test measures the amount of glucose attached to the red blood cells. The amount is the A1c and is shown as a percentage. Your A1c number can give you and your health care team a good idea of how well you've controlled your blood sugar over the previous 2 to 3 months. When you get your A1c result from a Kaiser Permanente lab, you'll also see another number called the estimated Average Glucose, or eAG. Understanding the eAG Your estimated Average Glucose (eAG) number is calculated from the result of your A1c test. Like the A1c, the eAG shows what your average blood sugars have been over the previous 2 to 3 months. Instead of a percentage, the eAG is in the same units (mg/dl) as your blood glucose meter. The chart shows the relationship between the A1c percentage and the eAG. If A1c % is: Your eAG is: 6 126 6.5 140 7 154 7.5 169 8 183 8.5 197 9 212 9.5 226 10 240 10.5 255 11 269 11.5 283 12 298 What the Numbers Mean The A1c and eAG reflect your average blood sugar over a period of time. These numbers help you and your doctor see how well your treatment plan is working. The higher your A1c and eAG numbers are, the higher your chances for having long-term health problems caused by consistently high blood sugar levels. These problems include heart attacks, strokes, kidney failure, vision problems, and numbness in your legs or feet. The lower your A1c and eAG numbers, the lower you Continue reading >>

Hba1c Units Converter - Dcct To Ifcc

Tweet Since June 2011, the way HbA1c values are reported has switched from a percentage to a measurement in mmols/mol. To make sense of the new units and compare these with old units and vice versa, use our HbA1c units converter. Why did HbA1c units change? The old, percentage way of reporting HbA1c values is known as the DCCT (Diabetes Control and Complications Trial) units. The new mmols/mol values are known as the IFCC (International Federation of Clinical Chemistry) units. See also: European countries have been using the IFCC units for a number of years and usage of the IFCC units by the UK will allow easier comparisons to be made between UK and European results. Haemoglobin molecules stay in the blood for around 3 months so the HbA1c test is able to give a measure of how glucose has interacted within our blood over up to a 3 month period. Getting familiar with the HbA1c unit changes Download a free chart which converts HbA1c in % units to mmol/mol and vice versa. Are the new HbA1c units related to blood glucose test units? The new HbA1c units (mmol/mol) looks similar to the units used for blood glucose tests (mmol/l) but they are measuring two different values. The HbA1c test measures how much haemoglobin in the blood has become glycated (chemically bonded with glucose). How does HbA1c differ to a blood glucose test? Blood glucose tests, by comparison, measure the concentration of glucose molecules present in the blood at the very time of the test.

The Formulas Equating Hba1c To Average Glucose Level Don't Work With Near Normal Blood Sugars?

NOTE: Important New Information Added to this post in OCT 2007. Please scroll to bottom to read! I got my new A1c result yesterday, the first in six months. It was 5.5%. During this period, my blood sugars have been significantly better than they had been for years. My fasting blood sugars have dropped about 20 mg/dl and my post-meal values have dropped by about 30 mg/dl. These changes have been measured many times using reference meals with known blood sugar outcomes. In the past, my A1cs were almost always 5.7%. The drop in A1c doesn't seem to capture the significant lowering of my blood sugars over this period. The usual formula to estimate the relationship between A1c and mean plasma glucose was derived from the DCCT study. That formula is: Mean Blood Glucose = (A1c * 35.6) - 77.3 Applying this formula, an A1c of 5.5% is supposed to correspond to a mean plasma glucose of 118.5 mg/dl and an A1c of 5.7% is supposed to correspond to a mean plasma glucose of 125.6 mg/dl. Neither of these values correspond to anything I have ever seen in my testing, and I test a lot and at many different times of day. My 30 day meter average, based on 150 measurements, has ranged between 98 and 103 during this period. There is another, less cited formula that works better, at least for me. It is called "The Nathan Formula" it is: Mean Plasma Glucose = (A1c * 33.3) -86 This formula yields a mean plasma glucose value of 97 mg/dl, which comes much closer to what my meter's 30 day average has looked like throughout this period. Here's a calculator that will give you the Nathan Formula A1c/Mean Plasma Glucose equivalents: A1c Calculator However, I think the most important point is this: despite doctors' reliance on A1c it is not a particularly accurate measurement of what your blood sugars ha Continue reading >>

What’s The Difference Between Hemoglobin A1c And Blood Sugar?

The info I'm about to share was triggered by a comment left by Jim. He said: “One of the things that has confused me since being diagnosed Type2 is blood sugar and A1C.” Of course I realized that many people are in the same boat, wondering, what on earth is the difference between hemoglobin a1c and blood sugar! If that sounds like you, by the time you finish reading through the below info, it should all be crystal clear – no more confusions. Blood sugar levels When you take your fasting glucose (aka morning blood sugar levels) or measure 2 hours after a meal, you generally do it on a daily basis so you can get a mg/dL or mmol/l reading (depending where you live in the world). Measuring daily levels is necessary because as Jim said: “When you're in in the trenches like us, it seems to me focusing on the daily readings makes sense because we can affect those immediately (good or bad).” And that's exactly right. Even though your levels will change daily, they give you immediate feedback on your level of control. Daily readings are influenced by diet, exercise, sleep, stress, lifestyle, medications and illness, which is why they can be up and down. Your goal is to hit daily averages that are within the normal range, majority of the time. Diabetes Blood Sugar Level Goals Note that ranges can vary slightly depending on what organization or healthcare provider you see. But generally your goals are to reach the following average numbers on a daily basis: Time to Check mg/dl mmol/l Upon waking before breakfast (Fasting) 70-130 (Ideal under 110) 4-7.2 (Ideal under under 6.1) Two hours after meals Under 180 (Ideal is under 140) Under 10 (Ideal is under 7.8) Bedtime 90-150 5-8.3 What is hemoglobin a1c?

Understanding Your Hba1c

You’ve heard about a diabetes test called a hemoglobin A1C. It’s sometimes shortened to HgbA1c or HbA1c or just A1C. Hopefully, you know what yours is. But do you know what it means and what to do with the information? Hemoglobin is what makes red blood cells red. It consists of several proteins wrapped around an iron-based molecule called heme. Heme attaches to oxygen and carries it to the cells. That’s why iron is important in our diets. We need iron to make heme to carry oxygen, so our cells can breathe. Glucose (sugar) molecules are also floating along in our blood. Glucose attaches itself to all kinds of proteins, including the hemoglobin in red blood cells (RBCs). When glucose levels are high, many more of them will attach. Hemoglobin coated with glucose is called “glycated” or “glycosylated” hemoglobin. Glycation (“sugar-coating”) may not harm an RBC, but it does tell us if the cell has encountered much glucose during its lifetime. The more glucose has been in the blood, the more RBCs will be glycated. This is what an HbA1c test measures. A1C isn’t measuring what your blood glucose level is at the moment. It measures how high glucose has been over the last two months or so. RBCs only live about 100–120 days in the bloodstream. Once they become glycated, they stay glycated for life, so the number of glycated RBCs (HbA1c) gives a good picture of how much glucose has been in the blood recently. The A1C test has several advantages over other tests such as a fasting blood sugar (FBS). You don’t have to fast for an A1C. It can be taken at any time of day. It doesn’t matter what you ate the day before or on the day of the test, because it’s not measuring your current sugar. Normally, between 4.2% and 5.6% of RBCs will be glycated.

A1c Calculator*

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.

What I did before A large part of my practice is focused on the management of diabetes. A key recommendation from the CDA guidelines is the achievement of A1C targets of 7%. Also, when appropriate, I encourage patients to perform self-monitoring of blood glucose levels. I try and teach all my patients what the role of the A1C is as well as how to use their home measurements to guide treatment. More often than not, patients either don’t test at home at all, or if they do, they test only in the fasting state in the morning, which may give falsely reassuring results as they assume the rest of the day looks similar. In followup visits, when patients are reviewing their lab results, I often found that patients assumed the A1C is a numeric average of 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 >>

What Do Your A1c Test Results Really Mean?

The hemoglobin A1c test, as we all know, is supposed to give a sense of your average blood glucose levels over the past three months. But here’s a question for you: have you ever tried to figure out what those average blood glucose levels actually are? Say you have an A1c of 6.5% — what, in mg/dl, does that translate to? Try searching Google — it’s hard to find an answer. To quote from a post I wrote a few years ago (see entry from 4:45), that’s partially because: “Not only is there no one standardized definition as to the correlation between A1c and mean glucose levels (JDRF says 1% = 24.4 mg/dl, ADA says 28.7), but different people have different correlations. For example, if you are a ‘high glycolator’ (more glucose sticks to your hemoglobin than the average) you can have a relatively high A1c but a low mean glucose. The speaker gave the example of a patient who had a 8.2% A1c, but a mean glucose of 159 mg/dl (he was speaking using the generally accepted idea that 7% roughly equals a mean of 154 mg/dl). Treat him more aggressively, and you’ll end up with hypos. And if you’re a ‘hypoglycolator,’ it’s the opposite.” Well, just this week, a new paper was published in the American Diabetes Association’s Diabetes Care journal that provides a more solid answer to this question than I’ve seen — even though, as I must warn you, personal variability (as described above) means there’s still no precise answer. In the study, researchers wanted to find out what your average blood sugar would have to be in three situations — fasting, after meals and before bed — in order to achieve a particular A1c. Here are their results: A1c test results of 5.5-6.49% were associated with an average fasting blood glucose level of 122 mg/dl. A1c test results Continue reading >>
