The invention discloses an
immunochromatographic test strip for quantitatively detecting
procalcitonin and a quantitative detection method thereof. The test strip comprises a PVC lining plate, a
nitrocellulose membrane (NC membrane), a combination pad, a sample pad and a water absorption pad; the PVC lining plate is sequentially overlapped and pasted with the sample pad, the combination pad, the NC membrane and the water absorption pad from left to right; the binding pad contains a nanogold labeled first
antibody for resisting
procalcitonin; the
nitrocellulose membrane is provided with a detection area and a
control area, fluorescent strips are respectively arranged in the detection area and the
control area, a detection line is arranged on the fluorescent strip of the detection area, an anti-
procalcitonin coated
antibody is used as the detection line, a
control line is arranged on the fluorescent strip of the
control area, and a procalcitonin
antigen is coated on the
control line. Compared with a
common method for detecting procalcitonin at present, the method has the advantages of simplicity and convenience in operation, quickness, convenience in carrying,
small sample consumption and the like, and meanwhile, the
linear range and the stability of detection are also improved.
