How does a QuantiFERON test work?
A QuantiFERON TB test is a simple blood draw. The blood is then tested in a laboratory to measure the strength of the blood’s reaction to tuberculosis bacteria, thus determining whether a person has been infected with TB bacteria.
Cases of positive TB test results require a follow-up chest x-ray for visual confirmation. The QuantiFERON blood test represents industry-standard testing for TB screening. However, false positives may occur. Consequently, the only way to confirm active tuberculosis in a patient is through a chest x-ray.
Chest x-rays are available to all patients who have a positive PPD skin test or QuantiFERON test result at Mobile Health.
Why choose a QuantiFERON tb test?
A QuantiFERON tb test has the advantages of requiring only one visit to a clinic and also of having a reduced likelihood of false negative/false positive readings as compared to a PPD implant. Also, this test is one of two Interferon-Gamma Release Assays (IGRAs) whole-blood tuberculosis tests approved by the FDA.
Potential drawbacks to the QuantiFERON tb test include the expense and the possibility of inaccurate readings among persons with reduced immune system performance.
