title: Point estimates of concentrations by simple immunoassays.
abstract: Point estimates can be generated by simple immunoassays when combined with a sequential statistical procedure. The method is called an extended simple immunoassay. A simple immunoassay for alpha-fetoprotein (counterimmunoelectrophoresis) was used to test the hypothesis that simple immunoassays are not restricted to qualitative "yet" or "no" results, but can provide quantitative results similar to radioimmunoassay. Potential benefits of this finding are discussed.
