Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
