Problems solved by technology

Twenty-one other HPAs are low-frequency or rare antigens whose putative higher-frequency "a" alleles have not been identified as antibody-specific
However, the described method does not use a device comprising a hydrophilized porous membrane and does not address (solve) the problems associated with the uptake of capture agents through the membrane

Abstract

The present invention relates to an in-vitro diagnosis device for detecting and / or identifying antigen and / or antibody from a sample of biological fluid, particularly from a sample of blood or sampleof blood components. The invention also relates to different uses of this device such as the detection and / or the identification of red blood cells antigens, platelet antigens, viralantigens, bacterial antigens, parasite antigens, the detection and / or the identification of anti-red blood cells antibodies, antiplatelet antibodies, antiviral antibodies, antibacterial antibodies and antiparasitic antibodies.

Description

technical field [0001] The present invention is in the field of immunodiagnostics. In particular, the present invention relates to an in vitro diagnostic device for the detection and / or identification of antigens and / or antibodies from a biological fluid sample, in particular from a blood sample or a blood component sample. The invention also relates to various uses of the device, such as detection and / or identification of red blood cell antigens or anti-red blood cell antibodies, platelet antigens or anti-platelet antibodies, viral antigens or anti-viral antibodies, bacterial antigens or anti-bacterial antibodies, parasite antigens or anti-parasite antibodies. In vitro methods using the devices of the invention are also part of the invention. Background technique [0002] Immunodiagnostic assays are methods that can be used in a variety of test formats and can be used to detect antibodies, antigens, or a combination of both. Typically, these detection tests are based on ...
