Hi all
I have bought a private VIT D test for my parents. When is the best time for them to test please? First thing in the morning on an empty stomach or is this test a bit more flexible?
Thanks

also the VIT B they take has Biotin in it so should they stop taking before their VIT D test?
Is it blood in a microtainer or the dried blood spot test where you put 4 spots of blood on some blotting paper type stuff?
Yes that’s the one
Which one, I've given both versions and asked which
agh so sorry it’s the 4 spots on a blotting paper
OK, so I asked the lab about this and they said the testing process is different from a serum blood sample and no biotin used in the process so no need to leave the B Complex off. However, if you want to be super cautious you could leave it off for a couple of days.
If they take Vit D they can continue with it up to and including the day before the test and the result will show what their dose is achieving .
First thing in the morning and water only before the test is for thyroid and iron tests.
What is the best test for testing Vitamin D? Ive heard different things!
