I noticed on a recent lab, I noticed Quest makes a distinction between the two tests. I was not previously aware there was an additional available. Since many here supplement with Vit D, I thought I'd point that out, although I'm not sure how critical it is compared to the importance of LC or UltraFilt on testosterone tests. See text for distinction below Vit D result.
