Diagnosis 2 hours - it is real!
Diagnosis of tuberculosis held in the bacteriological laboratory.
To study performed in the laboratory, the patient must take one or more samples of diagnostic material. Most often, TB infects the lungs, so the basic material for the diagnosis of this disease - the sputum. Effectiveness studies depends on the quality of sputum, so its collection should be carried out after instructing the patient in a special room under the supervision of health professional. If the patient fails to collect sputum alone, it can be assigned irritating inhalation.
Mycobacterium tuberculosis can be detected by different methods, which are characterized by different diagnostic sensitivity and duration of the study.
The fastest, simple and inexpensive method to identify the most infectious cases tuberkulezav within one working day - a microscopic examination of sputum smear stained with special dyes.
Bacteriological examination (egg inoculation of culture media) is the "gold standard" for the diagnosis of tuberculosis. Sowing detect Mycobacterium tuberculosis in a biological material of a patient, which allows to establish the diagnosis and determine which anti-TB drugs needed to treat the patient. This method is very sensitive, but the study long, colonies of mycobacteria in the culture medium usually grow no earlier than 3 weeks. DST grown cultures of Mycobacterium tuberculosis zanimaetesche 28 days. The result of research in the absence of mycobacteria in a sample is given at 8 weeks.
Conducting a study on the automated system VASTES MGIT 960 significantly faster than sowing. Growth of mycobacteria in vitro with a liquid medium has recorded an average cherez5-14 days. DST grown culture of mycobacteria takes another 14 days. The final result in the absence of mycobacteria in a sample is given 42 days.
Besides bacteriological studies can also be performed molecular genetic studies on tuberculosis, based on PCR (polymerase chain reaction). It is the fastest to date methods.
Rapid method of Xpert MTB / RIF detects Mycobacterium tuberculosis in the sample and determine their resistance to rifampicin (1 of 2 major anti-TB drugs) 2 hours.
Another quick method of molecular genetic diagnosis of tuberculosis - Hein-test, named for the producer. This method allows detection of Mycobacterium tuberculosis in the sample, and to determine the sensitivity to the principal and to the reserve antituberculosis drugs for 2 days.
Used in modern laboratory methods for diagnosis of tuberculosis can quickly and efficiently carry out a diagnostic study of the material to detect the causative agent of tuberculosis and to determine its drug sensitivity, to enable set correctly and timely diagnosis and adequate treatment of patients with tuberculosis.
