VD-T II (25-OH-Vitamin D Total)

Vitamin D plays an important role in maintaining calcium and phosphorus homeostasis. Vitamin D deficiency may lead to skeletal problems such as rickets, osteomalacia, progressive bone loss, and osteoporosis ^[1]. It may also lead to cancer, autoimmune diseases, and cardiovascular diseases . Thus, it is of great significance to assess the nutritional status of vitamin D in the human body on time and achieve individualized vitamin D supplementation.

Traceability

VD-T lI reagents are traceable to the ID-LC/MS/MS reference method calibrated by SRM 2972, ensuring accurate results while providing a basis for comparability of measurements between systems.

EQA

VD-Tll reagent has passed the CDC VDSCP program and participated in the DEQAS program with excellent results.

Currently, vitamin D insufficiency and deficiency are common problem worldwide. According to the study, more than 60% of people are deficient in vitamin D in the world , pregnant women, infants, children, elderly and obese people are especially at high risk of vitamin D deficiency.

According to the American Endocrine Society’s clinical practice guidelines, “vitamin D insufficiency” is defined as 25-OH Vitamin D <30 ng/mL.
