What's this test for?

This test is ideal if you're experiencing a persistent cough, unexplained weight loss, night sweats, or fatigue that won't go away. It's also a smart choice if you've been in close contact with someone diagnosed with tuberculosis, work in healthcare, travel frequently to areas where TB is common, or need TB clearance for a job, school, or immigration requirement. The test helps identify whether your body has been exposed to the bacteria that causes tuberculosis, even if you don't have active symptoms.

What happens after I get my results?

Your results will show up in your account as either Positive or Negative, with a clear explanation of what that result means. If your result is positive, the report will explain that follow-up steps like a chest X-ray or additional evaluation are typically needed to check for active disease versus a past exposure. If it's negative but you have ongoing symptoms or new exposure, retesting later may be worthwhile. You can download a standard lab report from your account anytime, and if you test again in the future, you'll be able to track results over time using the trends feature.

Who should consider this test?

Anyone with a known or suspected exposure to tuberculosis should consider this test, including household contacts of someone with active TB. Healthcare workers, people who live or work in shelters or correctional facilities, and those who have traveled to or lived in countries with high TB rates are also good candidates. It's also commonly required for school, employment, or immigration health screenings.

What symptoms indicate I may need this test?
Watch for a cough lasting three weeks or longer, coughing up blood, chest pain, unexplained weight loss, fatigue, fever, or night sweats. These symptoms can point to active TB disease, but many people with TB infection have no symptoms at all. If you've had close contact with someone diagnosed with TB, testing is worth doing even without symptoms.
How often should I retest?
If you had a recent exposure to someone with active TB, testing is usually done right away and sometimes repeated 8-10 weeks later, since it can take time for your body to show a detectable response. People in high-risk jobs like healthcare may retest annually as part of routine screening. If you have no new exposures and a past negative result, you likely don't need to retest unless your risk situation changes.
What should I do if my results are abnormal?
A positive result means your body has likely been exposed to TB bacteria at some point, but it doesn't tell you whether the infection is active or dormant. The next step is usually a chest X-ray and possibly a sputum test to check for active disease. If you have symptoms like a persistent cough or fever along with a positive result, seek medical care promptly since active TB is contagious and treatable.
What causes a false or unclear result?
Certain conditions, like a weakened immune system from illness or medication, can sometimes affect how your body responds and lead to an unclear result. Recent infections, some vaccines, or lab handling issues can also occasionally influence accuracy. If your result is indeterminate, retesting is usually recommended rather than assuming the result is final.
What is TB infection and why does it matter?
Tuberculosis is a bacterial infection that usually affects the lungs and spreads through the air when an infected person coughs or sneezes. It matters because TB can exist in a dormant, non-contagious state for years before potentially becoming active and serious if untreated. Catching an infection early, even without symptoms, allows for simple treatment that prevents it from progressing to active, contagious disease.
How can I lower my risk of TB exposure?
Avoid prolonged close contact with anyone known to have active, untreated TB, and make sure indoor spaces you spend time in have good ventilation. If you work in a high-risk setting like a hospital or shelter, follow recommended masking and screening protocols. Keeping your immune system strong through good sleep, nutrition, and managing chronic health conditions also helps your body fight off infection if exposed.
What's the difference between TB infection and TB disease?
TB infection (sometimes called latent TB) means the bacteria are in your body but inactive, causing no symptoms and no risk of spreading to others. TB disease means the bacteria are active and multiplying, which can cause symptoms and is contagious. This test detects exposure to the bacteria, but additional evaluation like imaging is needed to tell the two apart.

What this means

A negative result means no evidence of immune response to TB bacteria was found, suggesting you likely have not been infected with tuberculosis. A positive result would indicate your immune system has reacted to TB antigens, pointing to exposure at some point in time. This test alone can't tell whether an infection, if present, is active or dormant.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
