Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty-two times on one plate to assess intra-assay precision. Inter-assay Precision (Precision between assays) Three samples of known concentration were tested six times on one plate to assess intra-assay precision.
Spike Recovery
The spike recovery was evaluated by spiking 3 levels of human CA125/MUC16 into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 76% to 108% with an overall mean recovery of 87%.

| Serum | 30 | 38.89-663.06 | 100 | 124.51 |
Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of human CA125/MUC16 in this assay. No medical histories were available for the donors. n.d. = non-detectable. Samples measured below the sensitivity are considered to be non-detectable.
Product Data Sheet
Background: CA125/MUC16
The CA125 antigen, also known as MUC16, is a mucin protein that may be found in type I transmembrane or secreted forms that are used monitor the progress of epithelial ovarian cancer therapy. Expression of isoforms, proteolytic cleavage, and heavy N- and O- linked glycosylation produce forms of human CA125 that can vary from 200-5000 kDa in size. It inhibits NK cell activity, which is thought to contribute to immune evasion in peritoneal cancer and pregnancy.
