HbA1c Reliability

When is the HbA1c not reliable?



Answer: E) All of the above

Explanation: All these examples compromise a patient’s HbA1c reading. A recent blood transfusion can decrease a patient’s HbA1c because the blood being measured is not the patient’s own; renal failure and G6PD deficiency shorten the lifespan of the red blood cell and can lead to an artificially low HbA1c; and some medications such as aspirin can affect glycation and lead to an altered HbA1c.
