UniDiag’s ECLIA 25-hydroxyvitamin D Test Kit

Vitamin D is a kind of sterol hormone, which can promote the absorption of calcium in the intestine and regulate the calcium balance. Vitamin D is essential to form and maintain strong and healthy bones.

Vitamin D is mainly synthesized by human skin after ultraviolet irradiation, and a small part is taken from food or supplements. Possible causes of Vitamin D deficiency include insufficient sunlight exposure, insufficient nutrient intake, reduced absorption, metabolic abnormalities, or Vitamin D resistance. Recently, many chronic diseases such as cancer, hypertension, osteoporosis and several autoimmune diseases have been found to be related to Vitamin D deficiency.

25-hydroxyvitamin D is the main form of vitamin D in human body. Whether it is vitamin D taken from food or synthesized in vivo, two forms of vitamin D, vitamin D3 (cholecalciferol) and vitamin D2 (ergostecalciferol), are converted into 25-hydroxyvitamin D (25-oh-vd) by hydroxylation in the liver and then converted into active 1,25-dihydroxyvitamin D in the kidney. Vitamin D metabolites bind to carrier proteins in plasma and are distributed throughout the body. It is generally believed that 25 (OH) d is the most reliable clinical indicator to evaluate vitamin D status, because serum 25 (OH) d level reflects the in vivo storage level of vitamin D and is related to the clinical symptoms of vitamin D deficiency.

Stipulated in the China Clinical Guideline for Endocrinology and Metabolism, ECLIA is the recommended method for detecting Vitamin D level . UniDiag’s ECLIA 25-hydroxyvitamin D Test Kit uses a special production technique. The test kit features high sensitivity and good stability. It can realize real-time detection in a fast and convenient way. It is an excellent choice for Vitamin D deficiency test.
