Can you chew tobacco before a fasting blood test?

Answer 1

Found this online:

First, wait for any lab testing until you are healthy. Even if you have a cold, it can affect results. Fasting tests require nothing by mouth except small amounts of water for 8 to 16 hours (call your Doctor's office to find out the number of hours he/she wants you tested at specifically). This means:

NO SMOKING

NO GUM (not even sugarless!)

NO TUMS

NO BREATH MINTS

NO TOOTHPASTE

NO COFFEE (not even black!) Also, do not EXERCISE during the fasting period. Violating these rules will affect the reliability of test results. (You can eat normally in the days before the fast.)

Answer 2

Even though when people hear fasting, they assume no eating or drinking. However, smoking should be avoided as well because it can effect the test results.

Answer 3

This depends on what the blood test is for, but it may not matter if you use this before a blood test.

Answer 4

You should not chew tobacco before a fasting blood test. The chewing tobacco raises the blood glucose and it depresses insulin secretion.

Answer 5

Yes. You just can not eat food.

Answer 6

no

that's even worse
