Bloods fasting TSH & FT3

I’ve a blood test at 11.20 today so not taking any meds beforehand and fasting but can I have a coffee? My TSH is usually suppressed.

Can I take Gabapentin before thyroid tests also?

It’s taken 2 weeks to get this appt and couldn’t get an earlier one, but would a coffee affect the results much? Thanks

I think everyone will say just water- its a shame you could not get them done at your walk in bloods at hospital they usually start at 8am.its a long time to wait without food if you are up early.x good luck.

Hospital have told me water only but plenty as it stops blood being too sticky.
