| Abstract: |
| 本文用ACELISA法、ELISA-IgG法、HI法测定了临床诊断为麻疹的100对患者双份血清,其中8份三种方法都为阴性。余92对血清的三种方法诊断阳性率分别为ACELISA法98.9%,ELISA-IgG法82.6%,HI法69.4%,证明ACELISA法是诊断麻疹较好的方法,有敏感、特异、早期、多数仅需单份血清就能诊断等的优点。IgM抗体发病第二天开始出现,病后第2周达到高峰,一个月后明显下降或阴转,故ACELISA法诊断的适宜采血时期为发病第3~25天。 |
| English Abstract: |
100 paired sera from measles patients diagnosed by clinics were tested for further confirmation by IgM antibody capture ELISA (ACELISA), IgG-ELISA and HI tests.From them 8 cases showing negative results in their paired sera by all the three tests were considered not to be suffered from measles infection. The other 92 pairs of sera sho wed indices of recent measles infection by one to three of these tests and the positive diagnostic rates were different by each test, i.e. IgM-ACE LISA 98.9%, IgG-ELISA 82.6%, HI 69.4%. The AC ELISA was proved to be the best method for measles diagnosis with the advantages of sensitivity, specificity and earlier diagnosis.
Measles IgM antibody starts at the 2nd day of illness and goes to its peak by about the 2nd week. It decreases and begins to convert to negative by one month after onset of the disease. Thus, the optimal blood collecting time for measles diagnosis by ACELISA is considered approximately from the 3rd to the 25th day of illness. |
