What it is

This blood test, known as an interferon-gamma release assay (IGRA), such as QuantiFERON, checks whether the immune system reacts to tuberculosis proteins. It is used to screen for TB infection, often for work, school or immigration, and replaces the skin test for many people.

What the price covers

The price usually covers the lab test only. The blood draw is often billed separately, and a chest X-ray after a positive result has its own charge.
