Recovery
Matrices listed below were spiked with certain level of recombinant Periostin (POSTN) ,etc. by FLIA (Flow Luminescence Immunoassay) and the recovery rates were calculated by comparing the measured value to the expected amount of Periostin (POSTN) ,etc. by FLIA (Flow Luminescence Immunoassay) in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 80-95 | 85 |
| EDTA plasma(n=5) | 79-97 | 90 |
| heparin plasma(n=5) | 93-101 | 97 |
| sodium citrate plasma(n=5) | 83-97 | 88 |
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Periostin (POSTN) ,etc. by FLIA (Flow Luminescence Immunoassay) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Periostin (POSTN) ,etc. by FLIA (Flow Luminescence Immunoassay) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Periostin (POSTN) ,etc. by FLIA (Flow Luminescence Immunoassay) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Sample | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 83-97% | 87-94% | 82-103% | 83-101% |
| EDTA plasma(n=5) | 93-102% | 89-102% | 86-95% | 78-101% |
| heparin plasma(n=5) | 93-101% | 97-105% | 96-103% | 85-101% |
| sodium citrate plasma(n=5) | 94-102% | 80-94% | 84-101% | 89-96% |
Stability
The stability of 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 condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Test principle
Analyte-specific antibodies are pre-coated onto color-coded microparticles. Microparticles, standards, and samples are pipetted into wells and the immobilized antibodies bind the analytes of interest. After washing away any unbound substances, a biotinylated antibody cocktail specific to the analytes of interest is added to each well. Following a wash to remove any unbound biotinylated antibody, Streptavidin-Phycoerythrin conjugate (Streptavidin-PE), which binds to the biotinylated detection antibodies, is added to each well. A final wash removes unbound Streptavidin-PE and the microparticles are resuspended in buffer and read using the Luminex or Bio-Plex analyzer.The MFI developed is proportional to the concentration of analytes of interest in the sample.
