Question 1

what can cause a high hemoglobin a1c test?

Accepted Answer

Poor sugar control: Hemoglobin A1c measures average blood sugar over approximately the past 3 months. It is the measure of how much hemoglobin is attached to sugar molecules in the blood. Sugar in your blood binds to the hemoglobin of the red blood cell and stays there throughout the cell's lifetime (120 days). At high levels of blood sugar, more reacts w/ the hemoglobin, causing an elevated hemoglobin a1c.

Question 2

do you have to fast for hemoglobin a1c test?

Accepted Answer

No: For hba1c alone, no fasting is required, but it is often done with other tests, like cholesterol or blood sugar, for which fasting is indicated.

Question 3

what's a normal result for the  hemoglobin a1c test?

Accepted Answer

4 to 6: The normal range varies from lab to lab but is generally between about 4 and 6 percent.

Question 4

how long do you have to fast for a hemoglobin a1c test?

Accepted Answer

Hgb A-1-c: Does not require fasting.  It reflects blood sugar control over time.  The fast is usually for the blood sugar or lipid profiles drawn at the same time.

Question 5

hemoglobin a1c fasting test result  of 5.8 ? good, fair, ?

Accepted Answer

Pre-diabetes: Not good. It represents being prone to diabetes. You have time to reverse this process with lifestyle changes.

Question 6

how accurate is a hemoglobin a1c test in indicating hypoglycemia?

Accepted Answer

Poor: Hba1c is fair at detecting chronically high bgs, but very poor at detecting low bgs. Fortunately, true low bgs are very rare and almost never sustained or recurrent. The sensation of "hypoglycemia", when related to sugar at all in people not treated with diabetes medications, is usually the normal response to low-ish sugars, which corrects them and keeps the body well.

Question 7

can a hemoglobin a1c test tell if i have pre-diabetes?

Accepted Answer

Yes: As of 2010, we can use A1c to diagnose diabetes or pre-diabetes.  2 positive tests are still needed but A1c of 5.7-6.4% is considered pre-diabetes,  A1c of 6.5% or above is diabetes.  5.6% or less is normal.

Question 8

m58, does recent infection affect hemoglobin a1c test. ?

Accepted Answer

No: There Are some conditions that can affect your HgbA1c level but infection is not one of them.

Question 9

can eating before a hemoglobin a1c blood test make the levels higher than they really are?

Accepted Answer

No: Hemoglobin A1c is a test used to measure the sugar content in your blood that has occurred over the last few months.

By eating before a blood sugar test (usually done by finger prick) you can elevate the sugar levels in your blood, but this won't immediately change your hba1c. Hba1c comes from a build-up of "glycated hemoglobin" in the red blood cells over their life cycles, about 120 days.

Question 10

blood test showed low hemoglobin a1c (4.4%) everything else was normal. what could cause this?

Accepted Answer

Nothing bad: actually the low level does not mean much higher level could indicate that you average blood suger could be higher than normal and it depend how high it is
lower level could indicate normal or slightly lower blood sugar and most of the time it is normal
the test is design to check average blood sugar for the last 1-2 weeks and the sensitivity and the accuracy of the test is higher in high BS
