The QuantiFERON Test (QTF), also known as the blood tuberculosis (TB) test, is designed to detect Mycobacterium tuberculosis infection. This test is typically done when an employer suspects TB or requires health clearance. Results are usually available within 1-2 days, depending on the lab.
When Is the QuantiFERON Test Used?
The QuantiFERON test is ordered in several scenarios:
- Suspected TB Infection: When there is a clinical suspicion of TB.
- Positive TB Skin Test: To confirm the results of a positive TB skin test.
- Vaccinated Individuals: Even if a person has been vaccinated against TB, this test can provide accurate results.
Understanding the Results
- Positive Result: Indicates either an active or latent TB infection. Further tests are needed to determine the necessity of treatment.
- Follow-Up Tests: If lung infection is suspected, additional tests such as a chest x-ray, sputum smear and culture, or lung scan can be performed. The bacteria can also affect other parts of the body, including the spine, brain, bones, joints, lymph nodes, liver, spleen, intestines, kidneys, bladder, skin, and blood.
Treatment for TB
If TB infection is confirmed, it is commonly treated with antibiotics such as:
- Isoniazid
- Rifampin
- Ethambutol
Treatment can take several months to complete, depending on the severity and location of the infection.
