特异性
本试剂盒用于检测Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)，经检测与其它相似物质无明显交叉反应。
由于受到技术及样本来源的限制，不可能完成对所有相关或相似物质交叉反应检测，因此本试剂盒有可能与未经检测的其它物质有交叉反应。
回收率
分别于定值血清及血浆样本中加入一定量的Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)（加标样品），重复测定并计算其均值，回收率为测定值与理论值的比率。
| 样本 | 回收率范围(%) | 平均回收率(%) |
| serum(n=5) | 83-97 | 93 |
| EDTA plasma(n=5) | 81-91 | 88 |
| heparin plasma(n=5) | 90-101 | 93 |
| sodium citrate plasma(n=5) | 79-95 | 86 |
精密度
精密度用样品测定值的变异系数CV表示。CV(%) = SD/mean×100
批内差：取同批次试剂盒对低、中、高值定值样本进行定量检测,每份样本连续测定20 次，分别计算不同浓度样本的平均值及SD值。
批间差：选取3个不同批次的试剂盒分别对低、中、高值定值样本进行定量测定，每个样本使用同一试剂盒重复测定8次，分别计算不同浓度样本的平均值及SD值。
批内差： CV<10%
批间差： CV<12%
线性
在定值血清及血浆样本内加入适量的Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)，并倍比稀释成1:2，1:4，1:8，1:16的待测样本，线性范围即为稀释后样本中Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)含量的测定值与理论值的比率。
| 样本 | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 92-101% | 82-97% | 89-99% | 97-105% |
| EDTA plasma(n=5) | 84-101% | 90-104% | 78-98% | 89-99% |
| heparin plasma(n=5) | 83-91% | 92-103% | 81-105% | 91-105% |
| sodium citrate plasma(n=5) | 84-103% | 98-105% | 92-105% | 84-104% |
稳定性
经测定，试剂盒在有效期内按推荐温度保存，其活性降低率小于5%。
为减小外部因素对试剂盒破坏前后检测值的影响，实验室的环境条件需尽量保持一致，尤其是实验室内温度、湿度及温育条件。其次由同一实验员来进行操作可减少人为误差。
实验流程
1. 实验前标准品、试剂及样本准备；
2. 加样（标准品、样本、磁珠、检测溶液A）标准品或样本50μL及磁珠10μL，加检测溶液A50μL，
37°C酶标板振荡器孵育60分钟；
3. 磁吸洗板3次；
4. 加检测溶液B100μL，37°C振动孵育30分钟；
5. 磁吸洗板3次；
6. 加鞘液100μL，旋涡震荡2分钟后读数。
实验原理
将Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)抗体包被于磁珠，制成固相载体，向微孔中分别加入标准品或标本以及磁珠、标记VEGFA，标记的Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)和未标记的Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)与连接于固相载体上的抗体竞争结合，然后将未结合物洗净后，加入PE标记的亲和素，再次彻底洗涤后即可上机读数。MFI值和样品中的Ⅱ型前胶原羧基端原肽(PIICP)等多因子检测试剂盒(流式荧光发光法)呈负相关。
