Common questions.
How long does a TB skin test take?
The injection takes about 5 minutes. You must return 48–72 hours later to have the result read. If you need a single-visit option, ask about the QuantiFERON blood test instead.
Can I get same-day results?
Skin test results require a return visit in 48–72 hours. The QuantiFERON blood test is a single visit; results are typically available within 1–3 business days.
Do you provide a clearance letter for my employer?
Yes. We provide official written clearance letters accepted by most employers, schools, and immigration authorities.
What if my test comes back positive?
A positive result doesn't necessarily mean active TB. We'll order follow-up testing (chest X-ray, additional blood work) and refer you to the appropriate specialist if needed.
Do I need an appointment?
Walk-ins are welcome during open hours. Calling ahead at 240-332-4439 ensures minimal wait time, especially if you need results by a specific date.
