Does anyone know how long you need to fast for blood tests for HBA1C's? I have my blood test in the morning but the last time the secretary told me to fast from 8pm?? What does everyone else do? I always thought it was 12pm. I forgot to ask!!
i've never had to fast for a test, personally i think thats quite dangerous especially for type 2's.
My companion has a test scheduled for next week. It is a fasting test - only water after 9:00pm.
The test is to be done at 09:00 am. A measured volume of Lucozade consumed immediately afterwards and a second test two hours later.
She had pancreatitis a few years ago and has no foods with refined sugars.
Medics do this test about twice a year to check if insulin is being produced in sufficient quantity.
That sounds like a GTT - Glucose Tolerance Test. Usually only done to confirm a diagnosis of diabetes.
To check for insulin production, you'd have a C-peptide test.
