Abstract

The invention relates to a special protein liquid compound quality control serum with high stability for biochemistry, and belongs to the technical field of clinical in-vitro detection. The quality control serum is a compound liquid quality control serum which is mainly prepared from protective substances such as a buffer solution, a metal chelating agent, a surfactant, a protective agent, an ionic equilibrium agent and a preservative, and the quality control serum can detect 12 substances of antistreptococcic O, C reactive protein, a complement C3, a complement C4, IgM, IgA, IgG, prealbumin, rheumatoid factors, transferrin, total protein and albumin. Serving as the quality control serum of the 12 substances, the quality control serum has the advantages of being convenient to use and high in stability.
