检测原理: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Rat T3. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat T3. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat T3 in the samples is then determined by comparing the OD of the samples to the standard curve.

精密度

板内精密度(测定内的精密度):CV%<8%

三个已知浓度的样品分别在1个酶标板上测试20次,以评估分析板内精密度。

板间精密度(测定板间间精密度):CV%<10%

三个已知浓度的样品分别在3个不同的酶标板上测试40次,以评估分析板间的精密度。

回收率

分别往不同样本中添加已知浓度的T3, 做回收率实验,得出回收率范围和平均回收率
样本类型 回收率范围 平均回收率
血清(n=5) 92-106% 99%
EDTA 血浆(n=5) 90-105% 97%
Heparin 血浆(n=5) 88-103% 86%

线性

将添加有T3的样本分别稀释2倍,4倍,8倍,16倍做回收实验,得出回收率范围
样本类型 1:2 1:4 1:8 1:16
血清(n=5) 85-94% 79-96% 89-101% 82-90%
EDTA 血浆(n=5) 95-104% 85-96% 87-102% 91-99%
