Tuberculosis is considered one of the most severe diseases, and at present it is getting more communicable. A tuberculosis blood test, also called an interferon gamma release assay, helps you find out the TB germs present in your body.
What is IGRA?
This test is basically used in the diagnosis of infectious diseases like tuberculosis. Before moving ahead, let's first sort out an exact understanding of how the IGRA (interferon gamma release assay) helps in diagnosing tuberculosis infection. If you are looking for this test near you, then you should definitely refer to the Ganesh Diagnostic Centre. Here you will find out that this test is available at reasonable prices. It is a blood test that can help you diagnose tuberculosis infection. You can also find out the cost of the TB gold interferon gamma release assay at a reasonable price of only Rs. 1650, compared to the original price of Rs. 3300 at the market cost at Ganesh Lab only.
All we ensure is the satisfaction of our client, and this test commenced under the observation of highly skilled and professional physicians who draw blood, collect the blood, and then send it to a laboratory for further analysis. Tuberculosis is basically a communicable disease that spreads through the air when the patient sneezes, coughs, and spits somewhere. Tuberculosis basically spreads when a person comes into contact with the patient due to the various reasons through which germs spread and bacteria transfer from one person to another.
One of the most dangerous forms of tuberculosis is latent tuberculosis. Patients with this infection don't show any kind of symptom; they can't even spread a disease from one person to another, and they can give a positive blood test, but this tuberculosis is silently affecting the body of the patient, and it is deemed a one of sever and hazardous tuberculosis.
TB symptom
What all symptoms you will find with the tuberculosis patient are Night sweats, weight loss, cough, fever, weakness, chills, blood in the urine, and headaches—these are the kinds of symptoms you are required to immediately report to the doctor. whereas Ganesh Diagnostic and Imaging Centre Private Limited is one of the most trustworthy recommendations for you, but all we provide is the best care, quality, and service at a reasonable price.
IGRA Functioning
The IGRA blood test, also known as the Interferon-Gamma Release Assay, is a diagnostic tool used to detect tuberculosis (TB) infection. It is an alternative to the tuberculin skin test (TST) and is considered more specific and less affected by prior Bacillus Calmette-Guérin (BCG) vaccination. How the IGRA blood test works:
Blood collection:
- A medical professional takes a blood sample from a vein using a syringe or needle. The amount of blood required is usually small.
Laboratory tests:
- A blood sample is sent to a laboratory, where it is analysed.
White blood cell stimulation:
- In the laboratory, the collected blood is exposed to specific tuberculosis antigens. These antigens stimulate the release of interferon gamma (IFN-gamma), a substance produced by white blood cells (T cells) in response to tuberculosis infection.
Measurement of interferon gamma:
- The amount of IFN-gamma released by white blood cells is measured. This is typically done using an enzyme-linked immunosorbent assay (ELISA) or an enzyme-linked immunospot assay (ELISpot).
- Interpretation of results
- Based on the measured IFN-gamma level, the test result is interpreted as positive, negative, or equivocal.
Benefits of the IGRA blood test include
Increased specificity:
- Compared to the tuberculin skin test, the IGRA test is less likely to give false-positive results due to BCG vaccination or exposure to nontuberculous mycobacteria.
Individual patient visits:
- Unlike the tuberculin skin test, which requires two visits (one for skin examination and one for interpretation of results), the IGRA blood test can be performed in one visit. This makes it more convenient for both patients and healthcare workers.
Quantitative results:
- The IGRA test provides a numerical measure of IFN gamma release, allowing for a more objective interpretation of results.
Reduced need for aftercare:
- In some cases, the IGRA blood test can provide more meaningful results, eliminating the need for further testing and evaluation.
People with weakened immune systems are more susceptible to:
- The IGRA test may be more sensitive than the tuberculin skin test in people with weakened immune systems, such as those with HIV or those on immunosuppressive therapy.
It is important to note that the IGRA blood test is not an independent diagnostic tool for active tuberculosis disease. If the test result is positive or if active TB is suspected, further diagnostic tests such as chest x-ray, sputum culture, and molecular testing are usually required. This test is primarily used to screen for and detect potential tuberculosis infections.
