特異性
本試劑盒用于檢測(cè)促腎上皮質(zhì)激素釋放激素(CRF)，經(jīng)檢測(cè)與其它相似物質(zhì)無明顯交叉反應(yīng)。
由于受到技術(shù)及樣本來源的限制，不可能完成對(duì)所有相關(guān)或相似物質(zhì)交叉反應(yīng)檢測(cè)，因此本試劑盒有可能與未經(jīng)檢測(cè)的其它物質(zhì)有交叉反應(yīng)。
回收率
分別于定值血清及血漿樣本中加入一定量的促腎上皮質(zhì)激素釋放激素(CRF)（加標(biāo)樣品），重復(fù)測(cè)定并計(jì)算其均值，回收率為測(cè)定值與理論值的比率。
| 樣本 | 回收率范圍(%) | 平均回收率(%) |
| serum(n=5) | 93-101 | 96 |
| EDTA plasma(n=5) | 83-96 | 90 |
| heparin plasma(n=5) | 78-94 | 86 |
| sodium citrate plasma(n=5) | 96-105 | 101 |
精密度
精密度用樣品測(cè)定值的變異系數(shù)CV表示。CV(%) = SD/mean×100
批內(nèi)差：取同批次試劑盒對(duì)低、中、高值定值樣本進(jìn)行定量檢測(cè),每份樣本連續(xù)測(cè)定20 次，分別計(jì)算不同濃度樣本的平均值及SD值。
批間差：選取3個(gè)不同批次的試劑盒分別對(duì)低、中、高值定值樣本進(jìn)行定量測(cè)定，每個(gè)樣本使用同一試劑盒重復(fù)測(cè)定8次，分別計(jì)算不同濃度樣本的平均值及SD值。
批內(nèi)差： CV<10%
批間差： CV<12%
線性
在定值血清及血漿樣本內(nèi)加入適量的促腎上皮質(zhì)激素釋放激素(CRF)，并倍比稀釋成1:2，1:4，1:8，1:16的待測(cè)樣本，線性范圍即為稀釋后樣本中促腎上皮質(zhì)激素釋放激素(CRF)含量的測(cè)定值與理論值的比率。
| 樣本 | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 88-97% | 78-89% | 86-96% | 78-97% |
| EDTA plasma(n=5) | 94-102% | 88-101% | 94-101% | 86-98% |
| heparin plasma(n=5) | 96-104% | 89-99% | 84-95% | 91-101% |
| sodium citrate plasma(n=5) | 93-101% | 90-103% | 81-93% | 87-103% |
穩(wěn)定性
經(jīng)測(cè)定，試劑盒在有效期內(nèi)按推薦溫度保存，其活性降低率小于5%。
為減小外部因素對(duì)試劑盒破壞前后檢測(cè)值的影響，實(shí)驗(yàn)室的環(huán)境條件需盡量保持一致，尤其是實(shí)驗(yàn)室內(nèi)溫度、濕度及溫育條件。其次由同一實(shí)驗(yàn)員來進(jìn)行操作可減少人為誤差。
實(shí)驗(yàn)流程
1、向?qū)嶒?yàn)板每孔內(nèi)加入200μL分析緩沖液以預(yù)濕；
2、實(shí)驗(yàn)前標(biāo)準(zhǔn)品、試劑及樣本準(zhǔn)備；
3、加樣（標(biāo)準(zhǔn)品、樣本、磁珠、檢測(cè)溶液A），標(biāo)準(zhǔn)品或樣本50μL，加檢測(cè)溶液A 50μL，及磁珠10μL，25°C酶標(biāo)板振蕩器孵育90分鐘；
4、磁吸甩干，加檢測(cè)溶液B 100μL，25°C振動(dòng)孵育30分鐘；
5、磁吸洗板1次；
6、加鞘液100μL，旋渦震蕩10分鐘后讀數(shù)。
實(shí)驗(yàn)原理
將促腎上皮質(zhì)激素釋放激素(CRF)抗體包被于磁性微球表面，制成固相載體。在微孔中同時(shí)加入待測(cè)抗原（標(biāo)準(zhǔn)品或樣本）、生物素標(biāo)記的抗原和微球。待測(cè)抗原與生物素標(biāo)記抗原對(duì)特異性抗體進(jìn)行競(jìng)爭(zhēng)結(jié)合。加入PE標(biāo)記的鏈霉親和素，上機(jī)讀數(shù)。MFI值（Median Fluorescence Intensity）和樣品中的促腎上皮質(zhì)激素釋放激素(CRF)濃度呈負(fù)相關(guān)。
