FIELD: medicine.
SUBSTANCE: invention refers to biology and medicine, namely to laboratory methods of examination. Detecting phosphatidyl serine on the erythrocyte membrane surface is ensured by fixing cells by glutaric aldehyde, washing in distilled water and placing on a slide processed with lanthanum chloride, mixing and studying cell aggregation by optical microscopy. Observing the erythrocyte aggregates testifies to the presence of phosphatidyl serine on the erythrocyte membrane surface.
EFFECT: invention provides developing simple, fast method requiring no special equipment and critical agents and used for detecting phosphatidyl serine on the erythrocyte membrane surface.
