DEVICE AND METHOD OF SIMULTANEOUS DEFINITION OF BLOOD TYPE, SEROLOGICAL CROSS-CHECK AND ANTIBODY ANALYSIS Russian patent published in 2009 - IPC G01N33/558 

FIELD: medicine.

SUBSTANCE: invention concerns research and analysis of biological materials. Invention includes membrane with input zone for liquid sample application at least two indicator zones which can interact with the analyte(s), and at least one absorption zone absorbing liquid after they pass indicator zones. Indicator zones are positioned between input zone and absorption zone. Flow directions (tracks) from input zone through respective indicator zones to absorption zone are almost parallel. At least two different tracks are present. Invention claims method of defining several analytes or their derivatives in liquid sample, involving sample application to input zone of membrane. Indicated amount of the sample is sufficient to maintain sample fluid passage in direction of absorption zone through indicator zones and formation of complexes by analytes or their derivatives in indicator zones.

EFFECT: possible simultaneous definition of cell and plasmatic sample parametres.
