Blood rest query

[Gnomic]

Hi all I have my blood test tomorrow at 10:50. I know not to take my meds (100mg Levo) until after but what I can’t remember is whether I can eat and drink as normal beforehand or is it supposed to be fasting? Blood test. Mainly worried about whether I can have coffee or not. Thank you all

Recommended on here to fast until after your bloods I'm afraid! Nothing but water.

It's always killer having to wait for my cuppa!! ☕

Thank you for getting back to me. I suspected that may be the case!

Eating can lower TSH and coffee (and other caffeine containing drinks) can affect TSH. So if TSH is important (GPs often adjust dose according to TSH rather than look at the FT4 and FT3 levels) then nothing but water before the test.
