Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level T were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level T were tested on 3 different plates, 20 replicates in each plate.

Serum(n=8) | 80-90 | 84 |
EDTA plasma(n=8) | 82-94 | 87 |
Urine(n=8) | 85-102 | 95 |
Samples were spiked with high concentrations of T and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
1. Add 50μL standard or sample to the wells, immediately add 50μL Biotinylated Detection Ab working solution to each well. Incubate for 45 min at 37°C |
|
2. Aspirate and wash the plate for 3 times |
|
3. Add 100μL HRP conjugate working solution. Incubate for 30 min at 37°C. Aspirate and wash the plate for 5 times |
|
4. Add 90μL Substrate Reagent. Incubate for 15 min at 37°C |
|
5. Add 50μL Stop Solution |
|
6. Read the plate at 450nm immediately. Calculation of the results |
