In this video, we’re going to talk about HbA1C. Is the A1C test accurate?
Although the A1C test is a great test to perform as part of your review, don’t rely on it alone.
What is the A1C test?
The A1C test can determine whether you have excessive blood sugar levels that mix with red blood cells. Diabetes would be present if your A1C result was 6.5 or higher. There is apparently a link between increased retinopathy and this high A1C test result.
If you decrease this number by 1%:
• Your death rate from diabetes goes down 27%
• Microvascular complications go down 37%
• Myocardial Infarction goes down 14%
However, about 30% of the population is anemic. If you’re anemic, the A1C test will be invalid.
Other things that could make the test invalid are:
• Sickle cell
• Iron disease
In a diabetic person, red blood cells expire far more quickly than they do in a healthy person. It can significantly influence what appears on the A1C findings if you measure the red blood cells after a brief exposure to glucose. This is so that the test can determine the length of time that the red blood cells are exposed to glucose.
Better tests would be:
• Fasting glucose
• Post-meal glucose
It may be related to the dawn phenomenon if you wake up with high blood sugar and ketones. You produce glucose from fat, ketones, and protein, which is what causes the dawn phenomena. You’ve had insulin resistance for a long time, which is why this is happening.
You don’t really need to be concerned about this. It’s just a part of the transition phase if you have had chronic insulin resistance.
