Blood Test Advice

I have a blood test booked for 8.40 next Monday.

The form says:

FBC, Ferritin, Liver function, Thyroid function, Vitamin D.

At the moment I supplement with Vitamins B12, B complex, C, D, K2 and Turmeric, Selenium and Magnesium.

I have stopped B complex but is there anything else I should stop before the test.

I know not to eat or take meds before the test.

Thank you.

so that’s all

Just don’t take vitamin D on morning of test

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

If you are on T3 ….day before test split T3 as 2 or 3 smaller doses spread through the day, with last dose approximately 8-12 hours before test
