The invention provides a measurement kit for serum amyloid protein A, and relates to the technical field of biomedical detection. The kit comprises a reagent R1, a reagent R2, a calibration product and a quality control product, wherein the reagent R1 comprises trihydroxy methyl aminomethane, sodium chloride, bovine serum albumin, alanine and saccharose; and the reagent R2 comprises trihydroxy methyl aminomethane, an anti-human amyloid protein A antibody latex particle, a liquid biological preservative, sodium carboxymethylcellulose, alanine, saccharose and lauryl glucoside. The kit adopts a latex immunonephelometry technology, so that a large number of samples can be detected at the same time by using a full-automatic biochemical analyzer. The kit is better in linearity, high in detectionsensitivity, correctness and precision, short in detection time, simple to operate and relatively low in economic cost.
