What's this test for?

This test is ideal if you've been exposed to someone with tuberculosis, work in healthcare or high-risk settings like nursing homes or correctional facilities, or are traveling from countries where TB is common. It helps detect latent TB infection before it becomes active disease, which is important for protecting yourself and others. Many people use this test for employment screening, immigration requirements, or simply peace of mind after potential exposure.

How should I prepare for this test?

No special preparation is needed for this test. You don't need to fast before your blood draw, and you can take your regular medications. Just show up to your appointment and the blood sample will be collected and processed within 16-48 hours while your white blood cells are still active.

What's included in this test?

Mitogen-Nil Nil Quantiferon(R)-Tb Gold Plus, 1 Tube Tb1-Nil Tb2-Nil

This advanced blood test measures your immune system's response to TB-specific proteins through interferon-gamma levels. It evaluates how your white blood cells react to TB antigens, which indicates whether you've been infected with tuberculosis bacteria. Unlike older skin tests, this blood-based approach is more accurate for people who've received the BCG vaccine and only requires one visit instead of two.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your TB test results mean and whether further evaluation is needed. These notes include personalized guidance on next steps, such as whether you need imaging tests, treatment for latent infection, or simply routine monitoring. You'll also get the standard lab report and can track your results over time using our trends feature, which is especially helpful if you need regular TB screening for work.
When will I get my results?
Your results are typically available within 1-3 business days after your blood sample is processed at the lab. The timing may vary slightly depending on the lab's processing schedule, but you'll be notified as soon as your results and doctor notes are ready to view.
Who should consider getting this test?
This test is recommended for healthcare workers, people who've had close contact with someone diagnosed with TB, immigrants from TB-endemic countries like those in Latin America, Africa, Asia, and Eastern Europe, and those working in high-risk environments like homeless shelters or prisons. It's also important for people with weakened immune systems or HIV who may be at higher risk of developing active TB disease.
What symptoms indicate I may need this test?
While latent TB infection typically has no symptoms, you should consider testing if you've been exposed to someone with active TB or have risk factors. Symptoms of active TB disease include persistent cough lasting more than three weeks, unexplained weight loss, night sweats, fatigue, fever, and coughing up blood, but this test helps detect infection before symptoms appear.
What is tuberculosis and why does it matter?
Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis that primarily affects the lungs but can spread to other organs. Many people have latent TB infection, where the bacteria are present but inactive and not contagious, while active TB disease makes you sick and can spread to others. Detecting and treating latent TB prevents it from becoming active disease, which is crucial for public health.
What does a positive result mean?
A positive result indicates your immune system has responded to TB proteins, suggesting you've been infected with tuberculosis bacteria at some point. This doesn't necessarily mean you have active TB disease, most positive results indicate latent infection where the bacteria are dormant. You'll need additional tests like chest X-rays and physical examination to determine if you have latent or active TB and whether treatment is needed.
How often should I get retested for TB?
Retesting frequency depends on your risk level and occupation. Healthcare workers in high-risk settings may need annual testing, while those in lower-risk positions might test every two years. If you've had a positive test before, you typically don't need retesting unless you develop symptoms, but if you continue to have TB exposure, your doctor may recommend periodic monitoring.
