This kit is the quantitative detection of content of folic acid in human serum samples.
Based on the principle of competitive method, the folic acid in the sample and the folic acid-BSA compound compete the binding site of the fluorescent marked folic acid antibody on the microspheres. After a particular wavelength excitation there will be fluorescence signal in the reaction zone, the strength of the signal is inversely proportional to the folic acid (FA) content in the sample.
The Reduction of folic acid helps to diagnose megaloblastic anemia (MgA) due to folic acid deficiency; erythrocyte folic acid determination is particularly valuable in determining folic acid deficiency when folic acid deficiency in the tissue is absent but no megaloblastic anemia occurs. In addition, it can be seen in erythrocyte hyper-proliferation, increasing of folic acid use ,such as hemolytic anemia. This kit is the quantitative detection of content of folic acid in human serum samples.
