Time of day for antiboidies & off iron for ferritin blood test?

[Guest guest]

Hi,

I am going to the lab soon for my thyroid antibody tests and ferritin

test.

Do I need to go off my iron before I have my ferritin tested? If so,

how many days? (I cannot remember what I did in the past.)

Can I get my thyroid antibodies tested at any time of day?

(for later on)

What time of day do we test or Free T3 and Free T4? Do I just skip

that day's Armour before the test?

Thanks,

Kathy
