Up until recently I never tested above 95, even postprandially. I do donate blood four times a year because my hematocrit runs high.<br /><br />Last week, just for grins, I ordered an HbA1c test, expecting the results to be around 4.8. I was shocked when it came back at 5.6!

My hematocrit was a little above normal- not sure why- maybe a little dehydrated- and my A1C was 5.9. Can't understand that since my BS was consistently 69-89 random, and 94-104 two hours after a meal. Rarely up to 115 two hours after.

Lab testing services mention that iron deficiency may lead to a falsely elevated A1c.

The issue...Karen,<br /><br />Have you developed retinopathy?<br /><br />The issue here is what makes the 5.5% A1c predictive of retinopathy in the normal population. <br /><br />Beyond that, what percentage of the NHANES study subjects would you estimate were eating a very low carb diet like your? A very small portion indeed, because the low carb lifestyle is one that very few people adhere to long term in Jennyhttps://www.blogger.com/profile/17384082448952856117noreply@blogger.comtag:blogger.com,1999:blog-30206473.post-79264656331060761802009-10-30T16:16:48.800-04:002009-10-30T16:16:48.800-04:00RE your assumption: "An A1c of 5.5% correspon...RE your assumption: "An A1c of 5.5% corresponds (in large populations) with an average blood sugar of 112 mg/dl (6.2 mmol/L).<br /><br />Since this group was made up of people not diagnosed with diabetes, we can make a pretty good guess at what kind of diet they were eating: One very high in carbohydrates.

If your red blood cell counts are low, it would have nothing to do with your iron levels. <br /><br />And yes, anemia will lower the A1c because with fewer cells there is less glucose bonded to those in the sample. <br /><br />If you are testing your blood sugar 1 and 2 hours after eating, you Jennyhttps://www.blogger.com/profile/17384082448952856117noreply@blogger.comtag:blogger.com,1999:blog-30206473.post-49402156939650884852009-10-30T11:49:49.907-04:002009-10-30T11:49:49.907-04:00You said:
