SARS患者康复期血清特异性抗体效价检测

An investigation on the levels of the specific antibody in the serum of convalescent SARS patients

目的 :SARS患者康复期血清特异性抗体的效价。方法 :采用间接酶联免疫法和双抗原夹心法。结果 :SARS患者康复期血清特异性抗体IgG水平在住院第 5周达最高值 ,IgM水平在住院第 3周达到最高值。SARS患者康复期血清IgG水平是IgM的 1～ 7倍。住院 5～ 7周的SARS康复期患者 ,其血清特异性抗体检测阳性率达 10 0 %。结论 :SARS患者康复期血清特异性抗体水平在住院第 5周达到最高值 ,其阳性检出率达 10 0 %。

Objective:To investigate the levels of the specific antibody in the serum of convalescent SARS patients.Methods:The specific antibody in the serum of convalescent SARS patients were detected by indirect ELISA and double antigen sandwich method.Results:The levels of the specific IgG antibody in the serum of convalescent SARS patients is up to the maximum in the fifth week, the levels of the specific IgM is up to the maximum in the third week. The levels of the specific IgG in the serum of convalescent SARS patients is 1-7 times than that of the specific IgM. The positive detection rate of the specific antibody during 5-7 weeks in the serum of convalescent SARS patients is up to 100%.Conclusion:The levels of the specific antibody in the serum of convalescent SARS patients is up to the maximum in the fifth week, and the positive detection rate of the specific antibody is 100%.
