Precision
Intra-Assay Precision (Precision within an assay) Three controls of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three controls of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Recovery for Human beta 2-Microglobulin Parameter Assay Kit
The recovery of human beta2M spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| EDTA Plasma (n=4) | 99 | 79-114 |
| Heparin Plasma (n=4) | 106 | 91-124 |
| Serum (n=4) | 101 | 85-122 |
| Urine (n=4) | 90 | 76-105 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human beta2M were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.
