The invention relates to a serum amyloid protein A (SAA) measuring kit, and a measuring method thereof, and belongs to the technical field of medicine biological detection. The kit comprises a reagent (1), a reagent (2), a calibration material, and a quality control material. The reagent (1) comprises Tris-HCl, sodium azide, and PEG-6000. The reagent (2) comprises Tris-HCl, emulsion particles with an embedded anti-human serum amyloid protein A antibody, sodium azide, octyl phenol polyoxyethylene, and methyl paraben. The calibration material comprises a serum amyloid protein A antigen, and sodium azide. The quality control material comprises a serum amyloid protein A antigen, and sodium azide. The provided serum amyloid protein A (SAA) measuring kit and measuring method thereof have the advantages that compared with the latex immunological turbidimetry technology, the analysis sensitivity is high, the results are accurate, the operation is simple, and the cost is proper, and thus the method is convenient for popularization.
