特异性
                        本试剂盒用于检测类胰蛋白酶(TPS)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类胰蛋白酶(TPS)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) | 93-102 | 98 | 
| EDTA plasma(n=5) | 98-105 | 102 | 
| heparin plasma(n=5) | 98-105 | 101 | 
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类胰蛋白酶(TPS)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类胰蛋白酶(TPS)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) | 91-101% | 81-93% | 96-105% | 82-99% | 
| EDTA plasma(n=5) | 95-105% | 91-99% | 92-99% | 85-102% | 
| heparin plasma(n=5) | 79-89% | 87-103% | 78-104% | 92-103% | 
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)标准品或样本100μL及磁珠10μL,
                                37°C酶标板振荡器孵育90分钟;
                            3. 磁吸甩干,加检测溶液A100μL,37°C酶标板振荡器孵育60分钟;
                            4. 磁吸洗板3次;
                            5. 加检测溶液B100μL,37°C振动孵育30分钟;
                            6. 磁吸洗板3次;
                            7. 加鞘液100μL,旋涡震荡2分钟后读数。
实验原理
将类胰蛋白酶(TPS)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,其中的类胰蛋白酶(TPS)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结合,然后加入生物素化的类胰蛋白酶(TPS)等多因子检测试剂盒(流式荧光发光法)抗体,将未结合的生物素化抗体洗净后,加入PE标记的亲和素,再次彻底洗涤后即可上机读数。MFI值和样品中的类胰蛋白酶(TPS)等多因子检测试剂盒(流式荧光发光法)呈正相关。
