title: [Laboratory diagnosis in tuberculosis].
abstract: The most reliable signs of tuberculosis infection is detection of M. tuberculosis complex in biological fluids and biopsy specimens from focus of lesions. The sensitivity of laboratory diagnostic methods is different for different biological materials, which dictates the utilization of a complex laboratory approach, including microscopy, bacteriological methods, detection of specific IgG, IgM, IgA, and polymerase chain reaction.
