Cash or insurance?
At 2 of 2 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 2 it is below every plan's rate.

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.
