Abstract
The invention discloses a rapid detection kit for blood residues. The rapid detection kit comprises a labeled antibody, a coated antibody and a colloidal gold test strip. The labeled antibody is obtained by treating human red blood cells, immunizing mice and purifying through a series of steps; the coated antibody is prepared by treating human red blood cells, immunizing a rabbit and then purifying through a specific process. The preparation process of the colloidal gold test strip comprises the following steps: preparing colloidal gold, incubating a labeled antibody and the colloidal gold, spraying and drying, treating a sample pad, drying, impression on a PVC (Polyvinyl Chloride) bottom plate pasted with a nitrocellulose membrane, drying, and finally cutting and assembling into a detection strip. The kit is rapid in detection and can meet the rapid turnover requirement of instruments; the accuracy is high, and subjective misjudgment is reduced; the sensitivity is as low as 50ng / mL, trace blood residues can be effectively detected, the risks of cross infection and medical negligence are reduced, and the method has remarkable advantages and application value in the field of blood residue detection of medical instruments.
