Immunoassay target tissues

Several considerations influence the suitability of the immunoassay as a qualitative or quantitative tool for the determination of tissue residues. These include the assay format, the end user (on-farm or laboratory use), effects of sample matrix on the analysis, cross-reactivity considerations, detection levels required of the assay, target tissues to be used in the assay, and the use of incurred or fortified tissues for validation of the immunoassay against accepted instrumental methods. Although these variables are often interrelated, each topic will be discussed in further detail below.
