Use of an Immunoassay as a Means to Detect Polychlorinated Biphenyls in Animal Fat
In this paper we describe the validation and utilization of an DELFIA (Reg.) immunoassay for detecting polychlorinated biphenyls (PCBs) in animal fat. The immunoassay incorporates a rapid sample processing protocol that has been optimised to detect concentrations of PCBs in animal fat at or above 200 ng/g. The limit of detection of the assay was less than 50 ng/g. When the action level for the DELFIA assay was set at 100 ng/g to detect samples having 200 ng/g or more PCBs, the false negative rate was estimated at 0.2 %. By utilizing the DELFlA assay system to select for positive samples and GC/MS analysis for conformation aI1alysis, an accurate and cost-effective program has been established for the high throughput detection of PCBs in animal products.
