FIELD: medicine.
SUBSTANCE: invention refers to medicine and is used for qualitative or quantitative liquid sample analysis for a number of analytes. A device comprises a membrane with a feeding section to apply liquid sample, two indicative sections to interact with analyte (or analytes), and one absorption zones (3) absorbing the liquid delivered through the indicative sections arranged between the feeding section and the absorption section. Flows from the feeding section through the indicative sections to absorption section are directed in parallel. The method involves applying the sample on the feeding section of said membrane. Amount of the sample is enough to maintain the sample liquid running towards the absorption section through the indicative sections and to ensure analytes and or their derivatives found in the liquid sample to form complexes in the indicative sections.
EFFECT: concurrent identification of blood-group substances.
