Three research methods are used to actively detect TB patients:
1.Radiation (mainly fluorography) - in adults and adolescents.
2.Microbiological examination of sputum and urine in persons with respiratory and kidney
symptoms - for adults, adolescents and, less frequently, children. 
3.Tuberculin-diagnosis - for children and adolescents.
The following groups are to be examined twice a year:
1.Conscripted members of the armed forces.

8.Persons released from pre-trial detention and correctional facilities - for the first 2 years after release.
9.Persons under investigation held in pre-trial detention centres and convicted persons held

SHALL BE CARRIED OUT:

time.
THE ADULT DISPENSARY AND
RECORDS GROUPS:
ADG 0 - individuals who need diagnosis of TB process activity (ADG 0A) and differential diagnosis (ADG 0B). The duration of the diagnostic period and the period of follow-up in ADG 0 should be 2-3 weeks and no longer than 3 months for test therapy.
THE ADULT DISPENSARY AND RECORD
GROUPS:
ADG I - patients with active forms of tuberculosis:
subgroup IA - with newly diagnosed disease (MBT (+), MBT (-));
subgroup IB - with relapsed TB (MBT (+), MBT (-));
Subgroup IB - for patients who spontaneously interrupted treatment or were not examined in time at the end of treatment.
IA TRO - tuberculosis of the respiratory organs.
IA TEL - tuberculosis of extrapulmonary localization.
Duration of diagnostic follow-up - determined by the timing of disappearance of signs of active respiratory TB, not to exceed 24 months.
THE ADULT DISPENSARY AND RECORD
GROUPS:
ADG II (ADG II ТRO, ADG II ТEL) - patients with active tuberculosis with a chronic course of the disease, mainly with bacteriuria and destructive changes.
IIA - patients in need of intensive treatment when clinical cure can be achieved.
IIB - patients with advanced disease who require general supportive care, symptomatic treatment and intermittent antituberculosis therapy.
The duration of follow-up in DST II is unlimited.
THE ADULT DISPENSARY AND RECORD
GROUPS:
ADG III (ADG III ТRO; ADG III ТEL) - persons who have been cured of tuberculosis, with or without major or minor residual changes, are at increased risk of tuberculosis recurrence, the persistence of clinical cure and the validity of this diagnosis after completion of follow- up in ADG I and II is monitored.
The duration of follow-up is 1 to 3 years.
THE ADULT DISPENSARY AND RECORD
GROUPS:
ADR IV - persons in contact with persons with tuberculosis.
ADR IVA - persons in household contact with an identified and unidentified bacterial specimen - follow up 1 year after the end of treatment for active tuberculosis or the death of the patient.
Two 3-month chemoprophylaxis courses within one year of identification of the source of infection and comprehensive examination twice a year are carried out.
ADR IVB - Persons who have occupational or industrial contact with people or animals with TB. The duration of observation is determined by the period of work in occupational hazardous conditions and occupational contact plus 1 year after its cessation.
