The invention discloses application of a
reagent combination for detecting pathogens in preparation of a kit for detecting the quality of a
blood product. The pathogens are selected from a
pathogen group consisting of HAV, HBV, HCV, HEV, TP, HIV1, HIV2, HTLV1, HTLV2, HBOV, TTV, HCMV, B19, DENV, ZIKV, WNV,
babesia,
trypanosoma krusei and plasmodium, and belongs to the field of medical examination.The invention further discloses a corresponding kit and a method for detecting the quality of the
blood product. By means of the kit, the lowest
detection limit of pathogens is 1.0 * 10 < 3 > copies / mL, the kit has good specificity and
repeatability, and an important technology is provided for screening and evaluating blood transfusion transmitted pathogens.
