When to take blood tests and what to test for?

Hi all

I was wondering if anyone had any suggestions on when is the best time would be to have my bloods taken, to determine accurately what my thyroid and vit levels are actually doing?

I am due to have repeat bloods after 6 weeks of starting my higher dose of levo.

I am currently taking 75mcg of levo at night and 3 sprays of D3/K at about 6:45 in the morning. I am generally feeling bette than I was a few months ago, but still do not feel at my optimum.

I have asked for TSH; T3; T4; Antibody; Vit D, B12, Renal profile and liver Fx. Is there anything else you think I should get tested for?

Thanks

Early morning - before 9 am - after fasting over-night. Leave 24 hours between your last dose of levo and the blood test.

Also ask for folate and ferritin. :)
