Want this question answered?
need not
No.
You only need to fast before blood work if you are having a fasting blood glucose blood test. Not each blood drawing will require you to fast. If you are required to fast, you may still drink water before your blood work.
yes
no because a blood test is about what your blood is normally like and if you fast you wont be your normal self
Yes. For 12 hours before getting your blood drawn.
You do not need to fast for a chickenpox blood test.
No you do not. I am answering as a laboratory technician of 15 years.
I don't think you have to fast for twelve hours if you are having blood sugar tested. I would say you need to fast for at least six hours to eight hours.
All blood tests require fasting, in order to be sure of their accuracy.
No, you don't need to fast for the blood test for chickenpox.
not prolong fasting only 3-6 hrs...
