特異性
本試劑盒用于檢測神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)，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神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)（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) | 79-103 | 84 |
| EDTA plasma(n=5) | 79-101 | 84 |
| heparin plasma(n=5) | 82-93 | 86 |
| sodium citrate plasma(n=5) | 86-103 | 93 |
精密度
精密度用樣品測定值的變異系數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神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)，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肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)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) | 92-105% | 94-101% | 99-105% | 78-102% |
| EDTA plasma(n=5) | 83-97% | 94-104% | 79-90% | 91-101% |
| heparin plasma(n=5) | 79-101% | 90-97% | 88-99% | 79-104% |
| sodium citrate plasma(n=5) | 85-102% | 99-105% | 79-94% | 92-99% |
穩定性
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、檢測溶液A）標準品或樣本50μL及磁珠10μL，加檢測溶液A50μL，
37°C酶標板振蕩器孵育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。
實驗原理
將神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)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、標記VEGFA，標記的神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)和未標記的神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)與連接于固相載體上的抗體競爭結合，然后將未結合物洗凈后，加入PE標記的親和素，再次徹底洗滌后即可上機讀數。MFI值和樣品中的神經肽Y(NPY)等多因子檢測試劑盒(流式熒光發光法)呈負相關。
