If you suspect TB in the first place recommended to pass fluorographic research. But this is not the only method that will require that the TB doctor was able to make the correct diagnosis.
A blood test for tuberculosis allows to determine the activity of the process occurring in the lungs. The erythrocyte sedimentation rate is elevated and is in the range from 40 to 80 mm/h For the recovery of the patient, the ESR is reduced.
Immunoassay blood test helps detect the presence of antibodies to mycobacteria. And serological research methods are based on detection of serum immunoglobulin G (IgG) or antibodies specific for mycobacterial antigens. Unfortunately, such methods do not give the physician grounds for an accurate diagnosis and apply only in those regions where the activity of tuberculosis is relatively low.
Based on the recommendations of the world health organization for suspected tuberculosis required to conduct microscopic sputum smear staining by the method of Ziehl-Nielsen. If smears of 5 or more mycobacteria tuberculosis is confirmed.
After separation of the culture professionals is no less important is the task of determining susceptibility to antibacterial drugs. This helps to prescribe effective treatment and prevent the threshold resistance of mycobacteria.
In addition, for the diagnosis of tuberculosis patient is prescribed fluoroscopy, radiography, tomography. Fluoroscopy is used for an indicative survey. While radiography is considered a very important examination, which exactly displays of pathological processes in lungs. Imaging is needed only for clarification and exploration of the details and boundaries of the lesions of the lungs.
Tuberculin (Mantoux) is massively in children and adolescents, in order to timely detect and prevent the spread of tuberculosis. The main criterion – the size of the papules. With negative reaction the diameter of the papules is not increased. If the child is infected with the mycobacteria, the pool increases by more than 5 mm. Such a child needs a detailed examination.
