[Possible use of polymerase chain test (DNA diagnosis) in detection of mycobacterium tuberculosis].

The polymerase chain test (PCT) (DNA diagnosis) is comparable with other routine diagnostic methods, but has a variety of advantages over then: it is much more highly sensitive and specific, provides results more promptly than culturing. The tests have indicated that the Polytub diagnostic kit may be recommended for use at medical facilities in Russia to detect tuberculosis pathogen DNA in the sputum, urine, exudate, and spinal fluid using PCT.
