Folate Test Question

[Tango2]

Hello

I am going to book a private folate test as my B12 was low. There appear to be two tests on the site I am looking at, one is Folate Serum and the other Folate (RBC).

Any Clues as to which one I should have?

Many thanks

Tango, serum folate would probably be the test your GP orders.

" Either a serum or RBC folate test may be used to help detect a deficiency. Some doctors feel that the RBC folate test is more clinically relevant than serum folate but there is no widespread agreement on this."
