The FIA test consists of:
1) a conjugate pad containing specific protein (antibody or antigen) conjugated with fluorescent microspheres (probe conjugate) and a control antibody robe conjugate.
2) a nitrocellulose membrane with immobilized proteins in the test area (T line) and a control line (C line).

After adding the specimen to the sample well on the test cassette, protein in the sample will interact with the probe conjugate on the probe pad. The NC membrane diffuses re-solubilized conjugate forward. As the sample moves along the devise binding reagents situated on the NC membrane bind to the target at the T and C line.

Concentration in specimen is positively correlated with the fluorescent density of the fluorescent microspheres, after the measure and calculation of the quantitative fluorescence immunoassay analyzer, then the analyzer would calculate the concentration according to the preset calibration curve in the machine and display the result. C line should appear in any cases, which indicates the reaction system is effective.
