ODM Best TT4 test kit Supplier – 25-OH-VD – Aehealth

2-hydroxyvitamin D is the main form of vitamin D in vivo. Vitamin D is a steroid derivative, which belongs to fat soluble vitamin.

Vitamin D is mainly synthesized by human skin after ultraviolet irradiation, and a small part is taken from food or supplements.

Vitamin D not only affects the metabolism of calcium and phosphorus, but also has a wide range of physiological functions.

It is an essential substance to maintain human health, cell growth and development, and is closely related to a variety of diseases.

There are two forms of vitamin D in human body, vitamin D3 (cholecalciferol) and vitamin D2 (ergocalcitol).

2-Vitamin D is converted into 25 hydroxyvitamin D25- (OH) VD by hydroxylation in liver, and then into active 1, 25- dihydroxyvitamin D in kidney.

The level of 25- (OH) VD in blood can reflect the storage level of vitamin D in human body, and it is related to the clinical symptoms of vitamin D deficiency.

More and more epidemiological and laboratory evidences show that serum 25- (OH) d level is related to rickets, osteoporosis, Parkinson’s disease, cardiovascular disease, hypertension, chronic kidney disease, type 2 diabetes and tumor in children. Therefore, the detection of 25 – (OH) VD is very important for the diagnosis and prevention of related diseases.
