背景:
试剂:HLA-DR_ECD两个不同批号的产品(下为A组和B组)(抗体交联物两个不同批号)
HLA-DR-ECD产品信息 | Type | Conjugate_lot | Conjugate Manufacture Date | A组(Test) | 20011 | 12/13/2023 | B组(Ref) | 20010 | 8/16/2022 |
血样:健康人全血(EDTA抗凝)
测试方法:CD3_PB+HLA-DR_ECD 复染
问题描述:A组和B组的在淋巴细胞群中阳性细胞百分比差异较大(Total Delta%=9.51%)
B组结果如下:
A组结果如下:
(1)CD3-/HLA-DR+
Test-Ref=35.1%-31.12%=3.98%
(2)CD3+/HLA-DR+
Test-Ref=51.84%-46.31%=5.53%
Total:3.98%+5.53%=9.51%
厂家给的回复如下:
As for your issue, this is due to abrightness difference between the conjugate used for your Ref and the one used for your Test. Since the HLA-DR staining is not a clearpositive population but a smear population on lymphocyte, having a brighterconjugate leaves to detection of more positive cells.
经验不足,针对厂家给的回复结果没办法判断是否正确,之前猜测是可能是原料批间差异没有控制好导致的。
希望老师们能帮忙答疑解惑,谢谢。
