25- hydroxyvitamin D assay kit

Vitamin D

Vitamin D is converted by hydroxylation to 25-hydroxyvitamin D (25-OH-VD) in the liver and then to the active 1,25-dihydroxyvitamin D in the kidneys. Serum 25-OH-VD level can reflect the human vitamin D storage level and is related to the clinical symptoms of vitamin D deficiency. Vitamin D3 promotes the absorption of calcium and phosphorus in the small intestine and affects the calcium metabolism of bone tissue, thereby maintaining the normal levels of blood calcium and phosphorus and promoting the calcification of bones and teeth. Vitamin D also has an inhibitory effect on the proliferation and differentiation of certain tumor cells, and low sunlight exposure has been associated with the high incidence and mortality of colorectal cancer and breast cancer due to its effect on the formation of active vitamin D.

Vitamin D deficiency can lead to different diseases.

Bone related diseases: rickets, rickets, osteoporosis, etc.

Cardiovascular diseases: arteriosclerosis, hypertension, heart disease, etc.

Infectious diseases: pulmonary tuberculosis, asthma, rheumatoid arthritis, etc.

Endocrine diseases: diabetes, insulin resistance, etc.

Tumor-related diseases: breast cancer, ovarian cancer, colorectal cancer, etc.
