通過ISO 9001、ISO 13485質(zhì)量體系認(rèn)證
特異性
本試劑盒用于檢測神經(jīng)肽Y(NPY)等多因子檢測試劑盒(流式熒光發(fā)光法)，經(jīng)檢測與其它相似物質(zhì)無明顯交叉反應(yīng)。
由于受到技術(shù)及樣本來源的限制，不可能完成對所有相關(guān)或相似物質(zhì)交叉反應(yīng)檢測，因此本試劑盒有可能與未經(jīng)檢測的其它物質(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神經(jīng)肽Y(NPY)等多因子檢測試劑盒(流式熒光發(fā)光法)（加標(biāo)樣品），重復(fù)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) | 80-93 | 80 |
| EDTA plasma(n=5) | 78-91 | 86 |
| heparin plasma(n=5) | 79-104 | 96 |
| sodium citrate plasma(n=5) | 91-105 | 97 |
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(nèi)差：取同批次試劑盒對低、中、高值定值樣本進(jìn)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(jìn)行定量測定，每個樣本使用同一試劑盒重復(fù)測定8次，分別計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)加入適量的神經(jīng)肽Y(NPY)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神經(jīng)肽Y(NPY)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 | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 84-97% | 98-105% | 99-105% | 90-104% |
| EDTA plasma(n=5) | 98-105% | 94-101% | 78-101% | 85-99% |
| heparin plasma(n=5) | 85-94% | 86-97% | 85-102% | 83-95% |
| sodium citrate plasma(n=5) | 96-103% | 88-95% | 82-96% | 88-96% |
穩(wěn)定性
經(jīng)測定，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(nèi)溫度、濕度及溫育條件。其次由同一實驗員來進(jìn)行操作可減少人為誤差。
實驗流程
1. 實驗前標(biāo)準(zhǔn)品、試劑及樣本準(zhǔn)備；
2. 加樣（標(biāo)準(zhǔn)品、樣本、磁珠、檢測溶液A）標(biāo)準(zhǔn)品或樣本50μL及磁珠10μL，加檢測溶液A50μL，
37°C酶標(biāo)板振蕩器孵育60分鐘；
3. 磁吸洗板3次；
4. 加檢測溶液B100μL，37°C振動孵育30分鐘；
5. 磁吸洗板3次；
6. 加鞘液100μL，旋渦震蕩2分鐘后讀數(shù)。
實驗原理
將神經(jīng)肽Y(NPY)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(biāo)準(zhǔn)品或標(biāo)本以及磁珠、標(biāo)記VEGFA，標(biāo)記的神經(jīng)肽Y(NPY)等多因子檢測試劑盒(流式熒光發(fā)光法)和未標(biāo)記的神經(jīng)肽Y(NPY)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競爭結(jié)合，然后將未結(jié)合物洗凈后，加入PE標(biāo)記的親和素，再次徹底洗滌后即可上機(jī)讀數(shù)。MFI值和樣品中的神經(jīng)肽Y(NPY)等多因子檢測試劑盒(流式熒光發(fā)光法)呈負(fù)相關(guān)。
