摘要

Test unit (1) for a body fluid, has a fluid holding channel (6) with at least two branch channels (4) from it leading into test chambers (3), each containing a different test substance (13,14), an extraction cylinder (5) is linked to each test chamber, with its extraction piston (8). Test unit (1) for a fluid, and especially a body fluid, has a fluid holding channel (6) with at least two branch channels (4) from it leading into test chambers (3), each containing a different test substance (13,14), in a base body (2) of a transparent plastics material. At least one test substance is in a powder form, or is bonded to a solid phase. An extraction cylinder (5) is linked to each test chamber, with its extraction piston (8). The extraction pistons are coupled together mechanically.
