Which vitamin D test?

I want to get a vitamin D test privately but am unsure which test to get. On the Medichecks websites there is a choice of:

Vitamin d 25 hydroxy

Vitamin D (1 25 dihydroxy)

Vitamin D2 & D3

Could anyone suggest which is best?

TIA Angie

craftyang Medichecks say on their Vitamin D

(1-25 Dihydroxy) blurb:

There are two vitamin D tests - Vitamin D (25 OH) and Vitamin D (1, 25 Dihydroxy).

Vitamin D (25 OH) is the better marker of overall D status. It is this marker that is most strongly associated with overall health.

The 1, 25 Dihydroxy test is venous blood draw, the 25 OH is a fingerprick test.

If you want to do the 25 OH test, then it might be cheaper at City Assays as it's £28 for their fingerprick blood spot test - vitamindtest.org.uk/
