Fasting blood test. Can I still drink water?

[Wuxiapian]

Does anyone know?

Many thanks in advance for any responses.

YES, and my GP advises to drink lots of water or the lest result comes back as you having a liver/kidney problem as everyone is dehydrated!!!

TEST result!

yes

I was told no

Fasting blood test is normally for glucose = fasting sugar.....water has no sugar so does not affect the result. If you're talking pre-op, that's different.
