How long must i 'fast' before taking a blood test?!
Question: If you are talking about a blood sugar test then you are supposed to stop eating and drinking the night before the test.
If you are talking in secret code about a drug test then you should probably "fast" about 3-4 weeks.

most test require 12 hrs, check with your doctor to be sure
12 hours
After a 12 hour fast, a range of 3.9 to 6.5 mmol/l (70.2 to 117 mg/dl) is normal. (a level of 6.7 to 7 mmol/l (120.6 to 126 mg/dl) is considered a sign of prediabetes)
what kind of blood test / i think its at least 8 to 12 hours
just over night,they tell you not to eat or drink after midnight before your test.
