The invention belongs to the field of clinical medicine detection, and discloses a quality control product of an inflammatory marker and a preparation method of the quality control product. The quality control product of the inflammation marker is composed of a matrix liquid and an inflammation marker component, wherein the matrix liquid is composed of a matrix, a 5-100 mmol/L buffer agent, a 0.01-5 g/L protein protective agent, a 5-100 g/L saccharide and a 0.05-5 g/L preservative; the inflammation marker comprises the following components: procalcitonin, C reactive protein, serum amyloid protein A, myeloperoxidase, interleukin-6 and lipoprotein related phospholipase. The quality control product of the inflammatory marker contains a plurality of inflammatory markers, so that the joint detection of different inflammatory items is realized. Meanwhile, commercial human serum or plasma is adopted as a matrix, the channel source is stable, large-batch production can be achieved, the clinical sample conformity degree is high, the universality is high, the matrix effect can be reduced to the maximum extent, and the uniformity, stability and other performance are good.
