Tuberculosis is a chronic infectious (communicable) disease caused by the tuberculosis mycobacteria (Mycobacterium tuberculosis), which commonly affects the lungs. Based on WHO data, one third of the global population is infected with tuberculosis mycobacteria and about 2 million individuals die from this disease every year. Tuberculosis is an infectious (communicable) disease, which is spread by airborne particles: coughing, sneezing, by hands contaminated by secretions of the respiratory tract or other contaminated items. This disease spread when the infected person coughs, sings, laughs or speaks and other individuals inhale air contaminated by the bacteria. One individual with tuberculosis can infect up to 10–15 people in one year.
Tuberculosis tests facilitate the diagnosis of tuberculosis infection which is caused by tuberculosis bacteria known as Mycobacterium tuberculosis.
Early diagnosis of tuberculosis, before disease progression, helps to protect both the patient and those around them– a contaminated individual who has not developed the disease cannot spread the infection.
Advanced registration is not required for these tests.

Good to know
- Individuals who have been in contact with someone already infected with tuberculosis;
- Those living in an area of increased risk (prison facility, healthcare establishment);
- HIV infected individuals;
- Individuals taking immunosuppressants;
- Those travelling to countries where there is a high incidence of tuberculosis;
- Those complaining of severe cough, lasting for 3 weeks or longer.
In Lithuania new-born babies are vaccinated against tuberculosis with the BCG vaccine. They develop a temporary immunity against the tuberculosis causative agent. Pre-school children have an intracutaneous Mantoux test to verify that they are not infected with tuberculosis.
During the Mantoux test a certain amount of inactivated proteins of different mycobacteria is injected subcutaneously in the medial forearm side. A physician assesses the skin reaction 2-3 days later. Assessment of the Mantoux test is aggravated by the BCG vaccine which usually leads to a false positive reaction. A positive Mantoux test in BCG-vaccinated people does not necessarily mean that they have tuberculosis.
The QUANTIFERON – TB GOLD PLUS® test helps to find out whether you have tuberculosis or some other respiratory disease. In the case of a positive test result and the presence of other clinical symptoms, tuberculosis diagnosis can be confirmed and timely treatment initiated. The QUANTIFERON – TB GOLD PLUS® test is recommended by the World Health Organisation for diagnosis of latent (occult) tuberculosis, the results of this test are not affected by BCG vaccination. This is the most accurate test for tuberculosis diagnosis.
QUANTIFERON – TB GOLD PLUS® test is carried out with a blood sample.

Persons infected with tuberculosis bacteria do not experience any of the symptoms characteristic of tuberculosis. They can experience mild fever and general weakness, however they have no local tuberculosis characteristic lesions and they do not spread tuberculosis bacteria.
Many individuals infected with tuberculosis bacteria never get lung tuberculosis. Tuberculosis bacteria in the body of these individuals remain inactive and do not cause the disease.
People with tuberculosis experience the symptoms characteristic of this disease. One of the most important symptoms is a severe cough lasting more than 3 weeks. By coughing and sneezing they spread the disease causative agents, as the tuberculosis bacteria stay viable in the environment for a long time and other people can be contaminated by them.
The period from primary contamination to the development of the active disease can last from several weeks to a few months or even longer.
If you have had contact with a person suffering from open lung tuberculosis you can be contaminated with tuberculosis bacteria and start spreading them after becoming ill. Tuberculosis bacteria are spread by individuals who have the open form of lung tuberculosis. First of all, the person inhaling tuberculosis bacteria becomes infected, the bacteria multiply in the body and cause tuberculosis, and the person can later spread the bacteria.
Some individuals get tuberculosis within a few days of being contaminated, before the immune system has started to fight the tuberculosis bacteria, others – after a few years, when the immune system becomes weakened. The majority of tuberculosis infected people do not get tuberculosis as the body is able to fight the bacteria and prevent them from multiplying.
