[Rationalization of the double-antibody ELISA for cortisol determination from microtest plates using the Sumal system].

A method for enzyme-immunologic determination of cortisol by double-antibody-precipitation using microtest plates instead of centrifuge-glass-tubes is presented. By the use of highly productive technology, e.g. the Sumal-system, connected with accession to computer-techniques, the demand for workers is considerable reduced, especially with analyses of greater series. Another advantage is the reduction of the demand for biochemicals to 20%.
