[Computerized data processing for radioimmunoassay (author's transl)].

The computer programm of Marschner et al. ((1974), Arztl. Lab. 20, 184-191) for the calculation of radioimmunoassay data by spline functions was improved with regard to immediate availability of quality parameters. The existing programm was adapted to a computer Siemens 4004/151. Methods are reported for obtaining an exactly reproducible and objective smoothing of spline functions. The additional modifications enable even unskilled technicians to use the programm.
