[The diagnostic value of the polymerase chain reaction in tuberculosis]
Abstract:
The comparative study of material obtained from tuberculosis patients in the Vladivostok Tuberculosis Dispensary was carried out with the use of polymerase chain reaction (PCR), the bacterioscopic and bacteriological methods. The study was made on different groups of tuberculosis patients (in the phase of the active course of the disease and after convalescence), patients with nonspecific pulmonary diseases and persons having contacts with tuberculosis patients. The study revealed that PCR was 2-3 times more effective than the other above-mentioned methods and made it possible to obtain results as early as 3-5 days after material was taken.
