[Combination of absorption-elution and gel-filtration methods for group identification of blood spot specimens].

It is proposed to combine the traditional method of microscopic assessment of the results of absorption-elution reaction and the gel-filtration technique with the use of the ScanGel immunohematology system (Bio-Rad Laboratories, USA) in blood grouping tests. The study was designed to select monoclonal antibodies suitable for the purpose and optimize conditions of gel filtration. It is concluded that the combined method allows for rapid differential grouping of the large number of blood spots, promotes objectivization of assay results, and lightens the work of the operator carrying out serial analyses.
