Product Code: VitD1155Q-25

Rapi-D Vitamin D test is a quantitative immunochromatography based one step in-vitro test. It is designed for the quantitative determination of total 25- hydraxy Vitamin D (25-OH vitamin D) in finger stick blood. This assay provides a preliminary diagnostic test result and can be used for screening of Vitamin D deficiency.

Rapi-D™ Quantitative Vitamin D Test utilises the principle of Immunochromatography, a unique two-site “Sandwich” immunoassay on a membrane. The test employs a very “Exclusive” pair of anti-25-OH Vitamin D Monoclonal Antibodies; one conjugated with colloidal gold and another one immobilized on the solid phase. This will selectively detect Vitamin D with a high degree of sensitivity and specificity.

As the test sample flows through the membrane assembly within the test device, the coloured anti-25-OH Vitamin D-colloidal gold conjugate complexes with 25-OH Vitamin D from the sample. This complex moves further on the membrane by the capillary action to the test region (T) where it is immobilized by another anti-25-OH Vitamin D coated on the membrane, leading to formation of a pink / purple coloured band, which confirms a positive test results. The intensity of coloured band in the test line region is 25-OH Vitamin D concentration-dependent, higher the concentration of 25-OH Vitamin D in the tested sample, the stronger the coloured band is. A control line is present in the test window to work as procedural control.

Clinical Significance

Vitamin D is a steroid hormone responsible for enhancing intestinal absorption of calcium and the regulation of its homeostasis. The two common forms of Vitamin D are Vitamin D2 and Vitamin D3. Vitamin D deficiency is now recognized as a global epidemic. Virtually every cell in our body has receptors for Vitamin D, meaning that they all require “Sufficient” Level of Vitamin D for adequate functioning. Therefore, now detecting (25-OH) Vitamin D level is considered as “Medically Necessary Screening Test” and maintaining sufficient levels not just to improve bone health, but to improve overall health and well-being.
