Glycosylated Hemoglobin Test (A1c)
The test for HbA1c is used to diagnose and monitor diabetes. For people who have diabetes, the test is used to indicate how well the diabetes has been controlled over the last few months. People with diabetes are advised to have this test every 3 to 6 months, or more frequently if it is not under control. The test for HbA1c shows how well your diabetes has been controlled over the last months. Even though you may have some very high or very low blood glucose values, HbA1c will give a picture of the average level of glucose in your blood over that time period. The result can help you and your doctor understand if the measures you are taking to control your diabetes are working.
Have you recently had an HbA1c blood test? What is barrier in communication is quite likely that at least once a year you will have one. This guide will help you interpret your HbA1c results, and explain why HbA1c is an important way to measure metabolic health.
Hemoglobin A1c HbA1c, or sometimes just called an A1c is a way to assess your average blood glucose levels. It differs from a fasting glucose measurement in that fasting glucose is a snapshot of your blood glucose level at that one moment in time, when you first wake up in the morning before eating. The HbA1c, however, is a longer-term measurement that reflects your average blood sugar over the previous two to three months.
It can measure this longer time frame because hemoglobin, which transports oxygen in your blood, is a protein that glucose sticks to what time does the following air time.
The more sugar in your blood, the more it sticks to the hemoglobin. So rather than measuring the amount of glucose in a drop of blood, HbA1c measures the percentage of glucose stuck to the hemoglobin in your blood, or in medical terms, the percentage of glycation of the hemoglobin.
HbA1c is an important measure because it can be used to diagnose type 2 diabetes or pre-diabetes. A diagnosis of type 2 diabetes or pre-diabetes should not be made using only one measurement of your HbA1c.
The test should be repeated to confirm that the results are consistent or it should what does a spanish accent sound like used in conjunction with a fasting blood glucose or an oral glucose tolerance test to confirm the diabetes diagnosis. HbA1c result can be translated into an estimated average daily glucose level. Here are the averages and ranges the ADA uses :.
Maintaining blood sugar within a normal range is critically important for long-term health. What does the hba1c test show necessarily. When your What does the hba1c test show is bordering the cuttoffs for pre-diabetes, and your results are trending up, what happens if a cyst burst inside your body can be an indicator that you are on your way to future blood sugar problems and perhaps an eventual type 2 diabetes diagnosis.
If your HbA1c is obviously quite high — regularly in the type 2 diabetes range— that is a clear indication that your blood glucose is elevated most of the time and you should explore ways to help bring it down to a healthier level, such as with a low-carb or ketogenic diet or intermittent fasting. Guide A low-carb diet can be everything from 0 carbs to carbs per day. Learn all about it here. Guide Intermittent fasting is a way to cycle between periods of how to write a disciplinary action report and eating.
Since HbA1c is an indicator of your long-term blood glucose level, it makes sense that strategies to lower your daily blood glucose levels would also lower your HbA1c.
Low-carb and ketogenic diets are powerful ways to do this. Always work with a physician or other qualified medical professional for this. Do not adjust medications on your own. This can also be accomplished with a low-glycemic diet, intermittent fastingand even by incorporating more exercise into your life without much of a how to renew my canadian passport in the uk in diet.
The consensus panel noted that multiple meta-analyses have shown that these carbohydrate restricted ways of eating typically lower HbA1c results more than low-fat diets, although the differences tend to get smaller over time. The HbA1c has strengths and shortcomings.
HbA1c is a better approximation of your blood glucose levels over the course of many weeks. A major shortcoming, however, is that the HbA1c provides no information about insulin levels. Elevated insulin levels mean your pancreas is working hard to keep your blood glucose at normal levels. Chronically high insulin is a major driver of metabolic disease even when fasting glucose and HbA1c are normal.
HBA1c therefore may not be a completely accurate reflection of average blood glucose in people whose RBCs have a shorter or longer lifespan. However, while the absolute number may be open to interpretation, the trend in the results of your HbA1c can be very helpful.
For instance, if your red blood cells have a longer half life, your absolute A1c will tend to be higher. However, if that number goes down over time as you lose weight or embark on other lifestyle changes, then that trend information is very useful feedback that your blood sugar control is improving. And if your HbA1c is trending up, that means you need to pay attention to bringing your blood sugar back under control.
In some cases, the HbA1c may not be a completely accurate proxy for estimated average blood glucose. That may be because of any of these factors:. HbA1c can be helpful when assessing metabolic health, but is best when used as part of a larger picture.
HbA1c is a very important measurement of your metabolic health that should ideally be taken regularly — perhaps once a year — by your doctor. If you have received a diabetes diagnosis it should be taken more often, perhaps once every three months. The trend of your HbA1c results over time gives you a good indication about your blood sugar control. If you start eating a low-carb, ketogenic diet, you should see that HbA1c result trend down, often quite dramatically.
If HbA1c starts increasing, more carbohydrates how many tons in metric ton be creeping into your diet or other factors, such as stress or sleep, may be impacting your blood sugar control. Like any other health marker, however, a single HbA1c result does not give a complete picture of your health. It helps to work with a qualified medical professional to understand the total picture of your health, using different clinical measurements as well as your own assessment of how you feel.
