What is the TB Gold (QuantiFERON) Test?
The TB Gold (QuantiFERON) test, also known as an Interferon-Gamma Release Assay (IGRA), is a modern blood test used to detect Mycobacterium tuberculosis, the bacteria that causes Tuberculosis. Unlike the traditional Mantoux skin test, a TB Gold test in Kolkata is highly specific and is not affected by previous BCG vaccinations, making it the most reliable method for identifying both latent and active TB infections.
Why Choose TB Gold over the Skin Test?
This test offers several clinical advantages for patients and healthcare providers:
- High Specificity: It eliminates false-positive results often seen in individuals who have received the BCG vaccine.
- Single Visit: Unlike the skin test which requires a follow-up visit after 48-72 hours, the TB Gold test requires only a single blood draw.
- Objective Results: The laboratory analysis provides a precise numerical value, removing the "reader bias" associated with measuring skin bumps.
- Latent TB Detection: It is exceptionally effective at identifying "sleeping" or latent TB, allowing for preventative treatment before the disease becomes active and contagious.
