Understanding the Need for a Tuberculosis Test

Tuberculosis or otherwise commonly known as TB is a chronic disease that mainly harms the lungs of the body. The bacteria causing tuberculosis typically spreads from one person to another via tiny droplets released into the air through sneezes and coughs. If a person is exposed to the risk of getting TB, he/she must get a tuberculosis test done right away.

Signs and Symptoms of TB

The human body has its own inbuilt immune system that usually prevents the bacteria from harming internal organs and prevents the person from becoming sick. However, when the immune system fails to perform, the following signs and symptoms of TB are witnessed.

•    Coughing that lasts long, approximately three or more weeks
•    Coughing blood
•    Pain the chest pain while breathing or coughing
•    Unexpected weight loss
•    Fatigue
•    Feeling feverish
•    Experiencing night sweats
•    Chills, and
•    Loss of appetite

TB, if left untreated can become severe in nature and affect other parts of the body as well. Commonly affected parts include the kidneys, spinal cord, the brain, etc. When TB occurs outside lungs, its sign and symptoms vary depending upon the organ that’s involved.

Test for TB

Off all the tests available for confirming or denying the presence of TB in a patient, the first and the foremost examination done by a physician is a physical analysis of a patient's condition. During a physical examination, the doctor studies the lymph nodes for swelling and listens to the sound made by the lungs during breathing.

Post a thorough analysis the physician may suggest some additional tests for checking the presence of this chronic disease in the body.

•    Tuberculosis blood test – Two main types of blood test for tuberculosis are QuantiFERON-TB Gold Test and T-Spot TB test. Each of these is highly useful in confirming or ruling out TB in a patient when exposed to a high risk of TB infection and have shown a negative response to a skin test. These tests require only a single visit to a pathology lab.

•    Tuberculosis Imaging Test – If a patient proves positive to a skin test for TB, he/she is then ordered a chest X-Ray of CT scan. Such imaging examinations showcase white spots in the lungs where the immune system of the body has barred TB bacteria or reveal changes in the lung caused by the bacteria.

•    Sputum Test – If an imaging test shows the presence of TB in the lungs, the physician will take a sample of the sputum (the coughed out mucus) to check for TB bacteria. A sample of sputum also helps in testing for drug-resistant strains for TB

Medical science has developed treatments against tuberculosis that are highly effective and efficiently remove TB bacteria from the body. TB test in India is offered by all the leading medical centres and pathology labs at the most reasonable cost.
