Introduction to Quantiferon TB IGRA Test

Mycobacterium Tuberculosis is the bacteria responsible for the infectious disease known as Tuberculosis. It easily spreads from one person to another through coughing and sneezing. Exposure to Mycobacterium tuberculosis can cause tuberculosis infection that may lead to tuberculosis disease. 

TB blood tests, or interferon-gamma release assays (IGRAs), are used to detect TB infection. A TB Test analyzes the symptoms. Tuberculosis is an infection that affects the lungs caused by a bacteria called Mycobacterium tuberculosis. In active TB, the person experiences the symptoms. However, in latent TB, TB is present in individuals' bodies but with no symptoms. 

People with latent TB do not show symptoms and cannot spread the infection to others. However, if left untreated, it may cause various complications and may transmit the disease. 

The TB Quantiferon test is helpful for people who have close contact with people with active TB, those who have recently traveled to or resided in TB-endemic regions, and people with weak immunity.

Test details in brief

Purpose of the IGRA Test

Here is the purpose of the IGRA test-

• The test measures a person's immune response to the bacteria that causes TB.
• The TB blood test is used to detect TB infection and TB disease.
• TB infection is when a person carries bacteria, but their immune system can keep the infection under control.
• TB infection is when a person carries TB bacteria, but their immune system can keep the infection under control. It is also called latent tuberculosis. People with TB infection do not show symptoms of TB and can't spread it to others. However, if left untreated, it may develop into a tuberculosis disease.
• Screening for TB Infection—This test is recommended for high-risk people to detect TB infection in people who have no symptoms and check if their immune system reacts to Mycobacterium Tuberculosis. 
• Diagnosing of TB Disease—The test is used when the patient has symptoms of tuberculosis. If the reports are positive, this indicates TB disease. A TB test can show that the person's immune system is reactive to Mycobacterium tuberculosis. However, your doctor may recommend an additional test to diagnose TB infection or disease. 

What is the IGRA Test Measure?

The Quantiferon TB IGRA Test detects the presence of Mycobacterium tuberculosis, which causes TB in the body. It helps determine whether a person has a TB infection or not. The test measures interferon-gamma (IFN-γ), which produces T cells in response to TB antigens. T cells are a kind of white blood cell and a part of the immune system. It assesses the immune response to TB and provides more accurate results than the TST. 

Preparation for the IGRA Test test

The IGRA test does not require any special preparation; you just need to follow the general instructions, unlike other blood tests- 

• Fasting- You don't need to fast before the test; you can eat as usual.
• No medication restrictions- Let your doctor know if you take any medications or supplements.
• Inform your doctor- Discuss any concerns or questions about the IGRA test with your doctor before the test. 
• Medical history- Share your medical history, including any recent illnesses, vaccinations, or travel history relevant to your TB risk.

The procedure of the IGRA Test 

The IGRA test is a simple blood test like other blood tests. Here is the complete process of the TB Test- 

• The phlebotomist will ask to fold the sleeve. He will then first clean the arm area with an antiseptic solution. After that, he will tie a band on the arm to make your veins more visible. 
• Next, the healthcare provider will insert the needle into the vein to collect the sample. You might feel a slight prick when the needle is inserted. 
• After blood sample collection, the phlebotomist will put a bandage or cotton gauze over it to stop bleeding. 
• The IGRA test will not take more than a few minutes. The lab will share the test results within three days of sample collection. You will be able to download test results online.

What do the IGRA Test reports indicate?

The IGRA Test results will be available in 3 days of sample collection. The test results may vary from lab to lab. However, the IGRA test results may show the following interpretations-

• The positive IGRA results mean that you are likely to be exposed to TB at some point. This could be latent TB or past infection.

• The negative IGRA result means low infection of TB, or TB bacteria, is not likely present in the body. 

• If the test results are uninterpretable, the result is invalid or borderline. 

The TB blood test does not diagnose TB. It only reflects that the person is infected with Mycobacterium Tuberculosis bacteria. Consult your test reports with your doctor to confirm TB disease. You must consult your test reports with your doctor as they may advise you on the best based on your medical history and risk factors. 

Furthermore, you should undergo follow-up tests and other clinical assessments if your TB blood test results are positive. A follow-up test may include a health review, a physical examination, and a chest X-ray.

What are the common symptoms of TB?

In some people, TB might be asymptomatic or latent, which means it does not show symptoms. However, people who have active TB may exhibit the following symptoms-

• Persistent cough 
• Fatigue and low energy
• Low-grade fever
• Night sweats
• Loss of appetite and weight loss
• Experiencing chills. 

These symptoms can vary between people and seem like other diseases. If you need more clarification about the symptoms, consult your doctor for a proper diagnosis.

Who should take the IGRA Test?

Some people must take the IGRA test-

• People having close contact with someone with active TB
• People who live in high-risk areas
• Healthcare workers, homeless shelter residents
• People with compromised immune systems
• People who have received the BCG vaccine

Consult your doctor to determine if an IGRA test is right for you. They can assess your risk factors and recommend the most appropriate action.

Knowing Your TB Risk: The Importance of the IGRA Test

The IGRA blood test helps detect past exposure to TB bacteria and determine whether the bacteria are inactive and not contagious. Early detection of latent TB allows for appropriate treatment time and helps prevent the bacteria from becoming active and infectious. A positive IGRA result requires further testing, such as chest X-rays or sputum analysis, to determine if the TB infection is active.

Moreover, a positive IGRA doesn't mean you're sick. With proper treatment, latent TB can be effectively managed. Consult your doctor and take an IGRA test to confirm your condition.
