ABSTRACT:
The present invention relates to a method for using a test card (1) comprising at least one fluid circuit, constituting a network of channels (3) and/or of compartments (17), for transferring at least one biological liquid from at least one inlet (2) to at least one outlet (6, 17), and a hydrophobic fluid is injected into the test card, into all or part of the network of said card, prior to the transfer of the biological liquid(s), said hydrophobic fluid filling the capillary spaces formed by the angles of the network of channels and/or of compartments of the card and avoiding the formation of bubbles and/or of dead volumes during the transfer of the biological liquid.The invention is of preferential use in the field of microfluidics applied to biology.
