What is the QuantiFERON Test?
The QuantiFERON test is a blood test that is used to screen for tuberculosis.
The QuantiFERON test was approved by the FDA in 2001 to help detect latent Mycobacterium tuberculosis infections.
How does the QuantiFERON test work?
The QuantiFERON Test is a type of Interferon-Gamma Release Assay, or IGRA, test. This test helps check for the
presence of a response to Mycobacterium tuberculosis.
Why do people get the QuantiFERON test?
Many people test positive for tuberculosis on the standard medical skin test. Unfortunately, there is a high
rate of false positives, usually because of prior vaccination with the Bacille-Calmette-Guerin (BCG) vaccine
administered for tuberculosis protection. Until the advent of blood tests like the QuantiFERON test, people
with a positive TB skin test who needed TB clearance would be required to get a chest x-ray (often annually).
What are other advantages to the QuantiFERON test?
The QuantiFERON test only requires a single visit whereas a PPD, also known as a TB skin test, requires 2
visits (placement and read). Depending on the lab, results for the QuantiFERON test can often be
obtained in 48 hours.
What are disadvantages of a QuantiFERON test?
The test requires a blood draw. Also, the blood has to be handled in a special way or else the QuantiFERON
test has to be repeated. Finally, acceptance of this test is not fully mainstream yet although
acceptance is increasing.
How much does a QuantiFERON test cost?
The cost of the QuantiFERON test ranges widely. Test costs can range from $150 to $500+.
Do I need to prepare in any special way for a QuantiFERON test?
No, and fasting is not required.
