This world TB day, we will tell you all the tuberculosis testing types and how they are done. Refer to this article for more information.
Tuberculosis (TB), a potentially fatal infectious bacterial disease affecting the lungs primarily, is caused by the bacteria Mycobacterium tuberculosis. It is disseminated when a person with active tuberculosis in their lungs coughs or sneezes and someone else inhales the TB bacteria-laden droplets. While most people are aware of the signs and symptoms of Tuberculosis, in this article, Dr. Neha, Consultant Microbiologist - National Reference Lab, Oncquest Laboratories Ltd, Gurugram explains the tuberculosis testing procedure.
Although the germs that cause Tuberculosis can live in your body, your immune system can generally keep you from getting sick. As a result, specialists have distinguished between the following:
The following are signs and symptoms of active tuberculosis:
Tuberculosis can also harm other body parts, including the kidneys, spine, and brain. The signs and symptoms of TB that affect organs other than the lungs may be different. TB in the spine, for example, can cause back discomfort, while tuberculosis of the kidneys can produce blood in the urine.
Separating is difficult, but separation with tuberculosis is a fantasy that only a few people can achieve. It's critical to get intensive treatment at the right time. Thus, if you are experiencing any of the above-mentioned symptoms, it is recommended that you should get tested for tuberculosis for confirmation.
During your visit to the doctor, he/she will look for swelling in your lymph nodes and listen to the noises your lungs produce when you breathe using a stethoscope.
Following Tests can be conducted for identifying Tuberculosis-
If you get a positive skin test, your doctor will most likely recommend a chest X-ray or a CT scan. There might be white patches in your lungs generated by your immune system blocking TB bacteria from entering your body, or it could be abnormalities in your lungs caused by active tuberculosis.

A skin test (tuberculin skin test) is the most prevalent method used for aiding diagnosis, though blood tests are becoming more popular. On the inside of your forearm, a little quantity of tuberculin is injected just beneath the skin. Only a minor needle prick should be felt. A health care professional will examine your arm for swelling at the injection site within 48 to 72 hours. The Tuberculosis infection is indicated by a hard, raised red lump. The size of the hump has an impact on the test result's relevance. However, the Tuberculosis skin test is unreliable and might lead to false findings.
As with the tuberculin skin tests (TSTs), IGRAs should be used as an aid in diagnosing infection with M. tuberculosis. These tests assess how your immune system reacts to tuberculosis germs. . They do not help differentiate latent tuberculosis infection (LTBI) from tuberculosis disease.
If your chest X-ray indicates Tuberculosis in lungs symptoms, your doctor may ask for the samples of your sputum (the mucus that comes up when you cough). These samples will help in analysing Tuberculosis bacteria. Sputum samples can also be used to detect drug-resistant for TB strains. This helps your doctor choose the most effective medications. The results of these tests might take four to eight weeks to arrive.
Tuberculosis is a painful disease to live with, but the good news is that it is curable. Thus it's even more important to treat it at the correct time because delayed treatment means forbidden treatment. Every breath you take is worth a million-dollar grin from your family or loved ones, so keep tuberculosis at bay and adopt for a healthy living.
