Is it crucial to fast before an a1c diabetes test? i didnt fast. i got there they told me it was fine and fasting wasnt needed for any of the tests i did. now my pcp is saying one of the 3 reasons why it may be pcos is my a1c, just want to be sure?

Elevated "A1C" may represent increased risk of diabetes (type 2), which can affect regularity of menstruation (lack of ovulation) and produce "PCOS". Consult a GYN physician for guidance, as PCOS can have other consequences , and use of oral bcp's will obviate these effects.

HbA1c averages your blood glucose over the last 3 months more or less. But check with lab.
