Sample Extract (Magnetic Bead Method) Tandem Mass Spectrometry

25OHD determination is the optimal indicator of vitamin D nutritional status. Tandem mass spectrometry can accurately determine the concentrations of 25OHD₂ and 25OHD₃ simultaneously, and has good method specificity and strong anti-interference capability, so it is generally considered as the gold standard for the detection of 25OHD in human serum.

Diseases Related to Vitamin D Deficiency:

• Skeletal and muscular systems: rickets, osteomalacia, hyperostosis, myasthenia, unbalanced fall, myalgia
• Cardiovascular system: myocardial infarction, arteriosclerosis, hypertension, ischaemic heart disease
• Endocrine system: diabetes mellitus, insulin resistance
• Immunity and infection: rheumatoid arthritis, infectious disease, systemic lupus erythematosus
• Tumor: breast cancer, prostate cancer, ovarian cancer, colon cancer, etc.
