Cash or insurance?
At the one hospital here that publishes insurer rates for this code, the cash price is below the highest rate a health plan has negotiated. If you have insurance but have not met your deductible, you usually pay your plan's negotiated rate, which falls somewhere in the "Insurers pay" column. Paying cash can cost less, but a cash payment usually does not count toward your deductible. Ask the hospital for both numbers before you book.
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.
