DEVICE AND METHOD FOR SIMULTANEOUS CARRYING OUT OF BLOOD GROUP DETERMINATION, SERUM CROSS-CHECK AND ANTIBODY DETECTION TEST

摘要

The invention relates to a device for the simultaneous qualitative orquantitative determination of several analytes in a liquid sample, comprisinga membrane (2) with a charging zone (5), for the application of the liquidsample, at least two indicator zones which can interact with the analyte(s)and at least one absorption region (3), which accepts the fluid after passingthrough the indicator zones, whereby the indicator zones lie between thecharging zone (5) and an absorption region (3), characterised in that the flowdirections (flow tracks) are essentially parallel from the application zone(5) through each indicator zone to an absorption region (3) and at least twodifferent flow tracks are present. The invention further relates to a methodfor the determination of several analytes or derivatives thereof in a liquidsample, comprising: application of the sample to the charging zone (5) of amembrane of the device as given in claims 1 to 8, whereby said sample ispresent in sufficient amounts to permit the sample fluid to flow in thedirection of the absorption region (3) through the indicator zones and topermit the analytes or derivatives thereof in the liquid sample to form acomplex in the indicator zone.
