“Can Thalassemia Trait Cause a Falsely High HbA1c? My Random Glucose Is Normal but HbA1c Is 6.6
33-year-old male.
Non-smoker.
No known medical conditions.
No medications.
My HbA1c came back at 6.6%, which is in the diabetic range, but my random glucose test was normal at 5.07 mmol/L.
At the same time, my MCV is low (64.8), and I may have thalassemia trait. I read that some blood disorders or abnormal red blood cells can affect HbA1c accuracy.
Could thalassemia trait cause a falsely elevated HbA1c result? Are these results potentiallyAnalysis misleading? Should I do a fasting glucose test or other tests to confirm whether I actually have diabetes?
