One genetic variant in particular, found only in African Americans, significantly reduces the accuracy of the HbA1c blood test used to diagnose and monitor the condition. This means around 650,000 African Americans in the U.S. could have undiagnosed type 2 diabetes if tested with the HbA1c test alone.
