目的建立血吸虫病诊断试剂IgG免疫血清国家参考品。方法收集血吸虫病疫区粪检筛查阳性病人血清和非疫区正常人血清,经标定和验证合格,制成冻干参考品。结果冻干参考品血清效价符合要求,2家协作单位用3种免疫学方法标定,结果一致。结论所制备的冻干参考品可以用于血吸虫病抗体诊断试剂的检定。 Objective To establish a national reference sample of schistosomiasis diagnostic reagent IgG immune serum. Methods The sera from schistosomiasis-infected patients were collected from the sera of patients with positive sera and non-infected sera. The samples were qualified and qualified for freeze-dried reference. Results Serum titer of lyophilized reference material was satisfactory, and the two cooperative units were calibrated with three immunological methods and the results were the same. Conclusion The prepared freeze-dried reference material can be used for the diagnosis of schistosomiasis antibody diagnostic reagents.
