The 25-hydroxyvitamin-d test kit is used to determine the content of 25-hydroxy-Vitamin D (25-OH-VD) in human serum, it is mainly used for the auxiliary diagnosis of vitamin D deficiency-related diseases.
The 25-hydroxy-Vitamin D in the sample and the monoclonal antibody in reagent 1 become immune complexes.
The antigenic determinant-DNA coupling template in Reagent 2 binds to the remaining monoclonal antibodies, and the unbound antigenic determinant-DNA coupling template and dNTPs are used to synthesize double-stranded DNA products under the action of polymerase.
This product binds to fluorescent dyes and will produce fluorescence which is proportional to the intensity of fluorescence and samples of 25-OH-VD levels.
Using a specific protein analyzer to measure the intensity of fluorescence, the concentration of 25-OH-VD is determined by comparing the fluorescence intensity of samples to the standard concentration.
Test time: 350 seconds.
Packing: 25 Tests/ Kit.
