Question : If my A1-C is 4.2 showing an average blood sugar of 74 is that good or low?

Answered by Dr. Binu Parameswaran Pillai (14 minutes later)

Brief Answer:
Normal level

Detailed Answer:
Good day,
Noted your concern.
HbA1c of < 5.7% is normal. Its't low. However, Hba1c measurement has few problems. MAny drugs and diseaes interfere with Hba1c levels. Low Haemoglobin (Hb) can cause a spuriously low level of HbA1c. Similarly, many other types of anemias are associated with unreliable HbA1c levels. Hence it is recommended to do a Fasting blood glucose as well.
