The Interferon Gamma Release Assay or IGRA test is prescribed by doctors to check for the presence of tuberculosis pathogen in a patient. The test is part of the various tuberculosis screening and panel tests that help identify the presence of the tuberculosis bacteria. This test is also known as TB Platinum QuantiFERON and QuantiFERON®-TB Gold.
Tuberculosis is caused by the bacteria Mycobacterium tuberculosis. While the bacteria predominantly attacks the lungs, the progression of the infection can affect other organs without timely intervention with medication. People who have been to places that are considered to be high in tb infection or people who work closely with tuberculosis patients are generally requested to get a screening test done.
Being infected by TB is not the same as having the disease. People infected can just be carriers of the pathogen as their immune system keeps the pathogen under check. In cases where the immune system fails to control the bacteria, it becomes a disease.
When a person shows the following symptoms, the doctors order for a TB IGRA test:
Once infected, the tuberculosis disease is of two types:
The test for tuberculosis is done to understand if the person is merely infected or is actively suffering from the tuberculosis disease.
The test requires the patient to have his/her blood samples collected. The process of drawing blood might cause some side effects like feeling light-headed or getting bruises around the area where the needle punctured the skin. These are nominal risks and usually go away with enough rest and a proper diet. For the actual process, an experienced phlebotomist can draw blood without causing much pain to the patient.
