Hemoglobin A1C

Hemo­glo­bin A1C is a blood test used to diag­nose and mon­i­tor dia­betes and pre­di­a­betes. The result is an aver­age of your blood sug­ar lev­els for the past three months. You do not need to fast for this test.

The A1C test mea­sures the per­cent­age of hemo­glo­bin in your red blood cells that are coat­ed with sugar. 

For some­one with­out dia­betes, a nor­mal A1C lev­el is below 5.7%. Any A1C lev­el above 5.7% will require addi­tion­al mea­sure­ments to deter­mine an accu­rate diag­no­sis of pre­di­a­betes or diabetes.
