Abstract
A swab analyzer with advantageous handling and detection sensitivity for the immunochemical detection of substances. The analyzer has a housing, an eluent application zone (a swabbing pen 2) and a reaction zone (6). The housing (1) has a local elevation with a central opening, from which a sampling and eluent application zone, designed as a porous swabbing pen (2), projects. The local elevation is provided with an at least partially circular collection groove (3) for receiving excess eluent. A window (10) is present in the housing (1) at a spaced location from the local elevation for evaluating the reaction zone (6) placed under it. The sampling and eluent application zone as well as the reaction zone (6) with the signal zones (7) are in capillary fluid connection with one another.
