[The determination of the group classification of sperm by the ABO system by means of the immunofluorescence reaction in a quantitative modification].

Quantitative immunofluorescence and the Stat software helps objectively assess the results of the test by mathematical processing and more reliably detect this or that AB0 antigen in the spermatozoa.
