检测恶性疟患者RESA抗体常用常规RESA-IFA试验。在208例恶性疟患者中,RESA抗体的阳性率为15.4％(32/208)。在常规RESA-IFA试验的基础上,加用FITC标记的第三抗体,再进行试验,即双重荧光抗体RESA-IFA试验,同批血样RESA抗体的阳性率为24.0％(50/208),提高阳性检出率达55.8％。
RESA antibody detection of falciparum malaria patients commonly used conventional RESA-IFA test. In 208 cases of falciparum malaria, the positive rate of RESA antibody was 15.4% (32/208). On the basis of conventional RESA-IFA test, FITC-labeled third antibody was added and then tested, namely the double fluorescent antibody RESA-IFA test. The positive rate of RESA antibody in the same batch of blood was 24.0% (50/208) Positive detection rate of 55.8%.
