特異性
本試劑盒用于檢測血管活性腸肽(VIP)等多因子檢測試劑盒(流式熒光法)，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血管活性腸肽(VIP)等多因子檢測試劑盒(流式熒光法)（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) | 85-105 | 88 |
| EDTA plasma(n=5) | 92-99 | 95 |
| heparin plasma(n=5) | 92-105 | 98 |
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(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血管活性腸肽(VIP)等多因子檢測試劑盒(流式熒光法)，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血管活性腸肽(VIP)等多因子檢測試劑盒(流式熒光法)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) | 91-101% | 95-102% | 83-97% | 80-89% |
| EDTA plasma(n=5) | 98-105% | 79-101% | 79-95% | 97-104% |
| heparin plasma(n=5) | 91-101% | 79-93% | 97-105% | 95-103% |
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、向實驗板每孔內加入200μL分析緩沖液以預濕；
2、實驗前標準品、試劑及樣本準備；
3、加樣（標準品、樣本、磁珠、檢測溶液A），標準品或樣本50μL，加檢測溶液A 50μL，及磁珠10μL，25°C酶標板振蕩器孵育90分鐘；
4、磁吸甩干，加檢測溶液B 100μL，25°C振動孵育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。
實驗原理
將血管活性腸肽(VIP)等多因子檢測試劑盒(流式熒光法)抗體包被于磁性微球表面，制成固相載體。在微孔中同時加入待測抗原（標準品或樣本）、生物素標記的抗原和微球。待測抗原與生物素標記抗原對特異性抗體進行競爭結合。加入PE標記的鏈霉親和素，上機讀數。MFI值（Median Fluorescence Intensity）和樣品中的血管活性腸肽(VIP)等多因子檢測試劑盒(流式熒光法)濃度呈負相關。
