[Screening methods for the detection of alpha-1-antitrypsin deficiency in blood serum]

In order to spread in occupational medicine the simple screening test allowing to detect the alpha-1-antitrypsin deficiency, the conformability of four procedures with the method of radial immunodiffusion has been analysed. From the received data it results that for the preliminary diagnostics of deficiency in mass examinations methods based on separation of proteins on the agar gel, determination on the gelatinous membrane and the method of rocket immunodiffusion are suitable.
