TB GOLD PLUS (IGRA)

The TB Gold plus test is a modern molecular diagnostic test used to determine Mycobacterium tuberculosis (TB bacteria) quickly and accurately. Unlike traditional sputum microscopy which has many drawbacks, this test uses advanced technology to identify TB and drug resistance within a few hours.

The TB Gold plus test is an important tool for the identification of tuberculosis in patients who have sneezing, sudden weight loss, fever or drug resistant problem. As India is among the developing nations where TB is a great burden to healthcare, the government has launched various health schemes to end TB in India before 2030 which is the sustainable development goal to eliminate it. Early detection helps to prevent the spread of TB and make things easier for treatment of TB patients. The price of doing this test is around INR 2700 to INR 4000.

What Is the TB Gold plus Test?

The TB Gold plus test, also called Interferon-Gamma Release Assay (IGRA), is a blood test used to detect infection with Mycobacterium tuberculosis, the bacteria that causes tuberculosis.

Unlike traditional skin tests, TB Gold plus does not require multiple visits and is not affected by prior BCG vaccination. It measures the immune system’s response to TB proteins in the blood.

This makes it highly useful for detecting latent TB infection — a stage where a person carries the bacteria but has no symptoms and is not contagious.

Why is the TB Gold plus Test Important?

1. Detects Latent TB Infection

In major cases, TB patients do not show symptoms. However, the bacteria become active in later stages, particularly if immunity weakens.

2. Helps Prevent Active TB Disease

Determining the TB early decreases the risk of complexity, which may damage lungs and other organs adversely.

3. Useful for High-Risk Individuals

Doctors often recommend this test for:

• Healthcare professional
• Weak immune systems persons
• Individuals in contact with TB patients
• Undergoing immunosuppressive therapy

4. Accurate Even After BCG Vaccination

TB Gold plus avoids this issue and provides more reliable results.
