Hi

I am due to go for my 10 hour fasting blood test on Friday. I know not to eat any food or have any drinks in those hours b4 and during the test. But i was wondering if i should avoid pasta and bread in the 24 hours b4 the test. Would not eating carbs make any difference to the test?
 
Hi purple moon,
If the test is a fasting blood test then having a very low level of carbs in the 24 hours before the test will certainly lower your BS when they test it. But what does that prove? - that if you gave up eating bread and pasta you could have permanently good BS levels!

If it is a glucose tolerance test then what your BS level is at the start of the test is simply a guideline. What they are looking at is how your body reacts to the glucose and whether your BS drops back to its starting point after 2 hours.

There are some types of test where you can frig the results, but the only person that is cheating is you!
