特異性

本試劑盒用于檢測免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)，經檢測與其它相似物質無明顯交叉反應。
由于受到技術及樣本來源的限制，不可能完成對所有相關或相似物質交叉反應檢測，因此本試劑盒有可能與未經檢測的其它物質有交叉反應。

回收率

分別于定值血清及血漿樣本中加入一定量的免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)（加標樣品），重復測定并計算其均值，回收率為測定值與理論值的比率。

樣本回收率范圍(%)平均回收率(%)
serum(n=5)80-10379
EDTA plasma(n=5)88-9893
heparin plasma(n=5)81-8884
sodium citrate plasma(n=5)97-105101

精密度

精密度用樣品測定值的變異系數(shù)CV表示。CV(%) = SD/mean×100
批內差：取同批次試劑盒對低、中、高值定值樣本進行定量檢測,每份樣本連續(xù)測定20 次，分別計算不同濃度樣本的平均值及SD值。
批間差：選取3個不同批次的試劑盒分別對低、中、高值定值樣本進行定量測定，每個樣本使用同一試劑盒重復測定8次，分別計算不同濃度樣本的平均值及SD值。
批內差： CV<10%
批間差： CV<12%

線性

在定值血清及血漿樣本內加入適量的免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)，并倍比稀釋成1:2，1:4，1:8，1:16的待測樣本，線性范圍即為稀釋后樣本中免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)含量的測定值與理論值的比率。

樣本1:21:41:81:16

sodium citrate plasma(n=5)82-101%85-92%96-104%89-105%

穩(wěn)定性

經測定，試劑盒在有效期內按推薦溫度保存，其活性降低率小于5%。
為減小外部因素對試劑盒破壞前后檢測值的影響，實驗室的環(huán)境條件需盡量保持一致，尤其是實驗室內溫度、濕度及溫育條件。其次由同一實驗員來進行操作可減少人為誤差。

實驗流程

1. 實驗前標準品、試劑及樣本準備；
2. 加樣（標準品、樣本、磁珠）標準品或樣本100μL及磁珠10μL，
    37°C酶標板振蕩器孵育90分鐘；
3. 磁吸甩干，加檢測溶液A100μL，37°C酶標板振蕩器孵育60分鐘；
4. 磁吸洗板3次；
5. 加檢測溶液B100μL，37°C振動孵育30分鐘；
6. 磁吸洗板3次；
7. 加鞘液100μL，旋渦震蕩2分鐘后讀數(shù)。

實驗原理

將免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)抗體包被于磁珠，制成固相載體，向微孔中分別加入標準品或標本以及磁珠，其中的免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)與連接于固相載體上的抗體結合，然后加入生物素化的免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)抗體，將未結合的生物素化抗體洗凈后，加入PE標記的親和素，再次徹底洗滌后即可上機讀數(shù)。MFI值和樣品中的免疫球蛋白M(IgM)等多因子檢測試劑盒(流式熒光發(fā)光法)呈正相關。
