Vitamin D, 25-OH, total 12L(Reference range:30-100ng/ml)
Notes: 25-OHD3 indecates both endogenous production and supplementation. 25-OHD2 is an indicator of exogeous sources such as diet or supplementation. Therapy is based on measurement of total 25-OHD, with levels <20ng/ml indicatevie of Vitamin D deficientcy, while levels between 20ng/ml and 30ng/ml suggest insufficiency.
What does that mean? What should I do to get back to normal level? Thanks!!
