Quantitative Proof of Vitamin D

Vitamin D deficiency is associated with impairment of the immune system (infections), cardiovascular diseases, cancer, hypertension, autoimmune diseases, diabetes and osteoporosis. An association with a higher rate of infections of the respiratory tract has been described. Vitamin D thus has a high clinical relevance.
Our specific and highly sensitive test system allows the quantitative determination of total 25 (OH) vitamin D. Both metabolised forms of vitamin D3 and vitamin D2 have been detected.
Serum levels of 25 (OH) vitamin D are considered a suitable indicator for the current vitamin D supply, because, as storage for vitamin D, they have the highest concentration of all vitamin D metabolites in the blood. In addition to diagnosing vitamin D deficiency, our ELISA is also very suitable for therapy monitoring of patients.
