FIELD: medical engineering, diagnostics in biochemistry, immunology. SUBSTANCE: apparatus comprises sensing element connected in series to commutator, signal generator, frequency divider, comparator element, AND element, analog/digital converter and digital display. Control input and second output of commutator are connected, respectively, to output and to input of element "Start" whose output is connected to second input of AND element. Second input of comparator element is connected to output of reference frequency generator. Sensing element is made of foil-coated glass fibres, in which two pairs of current-conductive paths are etched out. One end of paths terminates, respectively, in contact zones "Control" and "Test", whereas other end of both current-conductive paths terminates, respectively, in current-collecting zones "Control" and "Test". Contact and current- conductive zones are coated with noble metal layer, while current-conductive paths are coated with insulation material layer. Sensing element has cartridge made of sorptive material and is provided with corresponding depressions "Control" and "Test", inner surfaces of depressions being made ribbed. EFFECT: apparatus can be used for proximate diagnostics of particularly dangerous infections, including AIDS infection. |
