特异性
本试剂盒用于检测饥饿素(GHRL)，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饥饿素(GHRL)（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) | 96-105 | 101 |
| EDTA plasma(n=5) | 79-93 | 89 |
| heparin plasma(n=5) | 80-97 | 93 |
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饥饿素(GHRL)，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饥饿素(GHRL)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) | 80-105% | 99-105% | 86-94% | 90-102% |
| EDTA plasma(n=5) | 94-103% | 98-105% | 79-96% | 78-98% |
| heparin plasma(n=5) | 79-92% | 81-90% | 97-105% | 80-95% |
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、试剂及样本的准备；
2. 加样（标准品及样本）50µL，
加入50µL检测液A(临用前配制);
37°C温育1小时。
3. 洗板3次；
4. 加检测溶液B100µL，37°C孵育30分钟；
5. 洗板5次；
6. 加底物100µL，37°C孵育10分钟；
7. 读数。
实验原理
本试剂盒应用竞争抑制酶联免疫分析法测定标本中待测物质水平。将饥饿素(GHRL)单克隆抗体包被微孔板，制成固相载体，往包被抗体的微孔中同时加入生物素标记的抗原和待测抗原（标准品或样本），待测抗原与生物素标记抗原对特异性抗体进行竞争结合。温育后经洗涤去掉未结合物，然后加入HRP标记的亲和素，再次彻底洗涤后加入底物。加入底物后会产生辉光型光信号。发射光强度和样品中的饥饿素(GHRL)呈负相关。用化学发光仪测定相对光单位（RLU），计算样品浓度。
