Getting a tuberculosis (TB) test shouldn't require a frustrating maze of phone calls or surprise bills. If you need a screening for a new job, nursing school clinicals, or volunteer work, your local retail pharmacy clinic offers a streamlined path. At select Walgreens locations housing retail health clinics, a standard TB skin test generally costs between $30 and $75 out-of-pocket, depending on regional pricing and whether you need a separate placement and reading fee.
Understanding how retail health screening works helps you avoid the common trap of missing the mandatory return window, which voids the test and forces you to start over. Let's break down the actual expenses, the clinical process, and how to verify availability before you walk out the door.
The True Cost of Tuberculosis Testing at Walgreens
When paying out-of-pocket without health insurance, expect predictable flat-rate pricing at retail clinics located inside select Walgreens stores.
- TB Skin Test (PPD / Mantoux): Typically ranges from $30 to $65 for the placement, with some locations charging a separate nominal fee (around $30) for the mandatory 48-to-72-hour reading. Always ask if the quote covers both visits.
- Insurance Coverage: Many commercial health insurance plans cover occupational or educational screening if ordered or administered through an approved in-network provider. However, many retail clinics operate independently or require specific network tiers, so call the number on the back of your insurance card beforehand.
- Hidden Costs: If your skin test comes back positive, Walgreens clinics cannot provide the necessary chest X-rays or specialized management on-site. You'll incur additional costs when referred to an urgent care center or primary care physician for follow-up imaging.

How the Walgreens TB Testing Process Works
A standard tuberculosis skin test—officially known as the Mantoux tuberculin skin test—requires two separate, mandatory in-person appointments. You cannot complete this process in a single trip.
Step One: The Injection (Placement)
During your first visit, a nurse practitioner or physician assistant reviews your health history, examines your forearm, and injects a small amount of purified protein derivative (PPD) just beneath the top layer of skin. This creates a small, pale bump or wheal. The appointment takes about 15 minutes.
Step Two: The Return Visit (Reading)
You must return to the exact same clinic location 48 to 72 hours later. A clinician inspects the injection site for induration (a hard, raised area). Measuring this localized immune reaction determines your result. If you return outside the 72-hour window—such as arriving on day four—the test is invalid, and you must pay for a completely new test and restart the timeline.

Skin Tests vs. Blood Tests: What to Know
While Walgreens clinics primarily administer the traditional two-visit skin test, it's worth understanding your options if your employer accepts alternatives.
- PPD Skin Test: Inexpensive and widely accepted, but vulnerable to false positives if you received the BCG tuberculosis vaccine commonly administered outside the United States.
- IGRA Blood Tests (QuantiFERON-Gold): Requiring only a single lab draw with no return visit required for reading, blood tests are unaffected by the BCG vaccine. However, they are generally more expensive ($100 to $200+) and typically require an independent commercial laboratory like Quest Diagnostics or Labcorp rather than a standard pharmacy retail counter.
Common Mistakes to Avoid
- Assuming Every Walgreens Has a Clinic: Many Walgreens stores are retail pharmacies only and do not feature staffed healthcare clinics. Always use the online scheduler to filter for locations with active clinical providers.
- Booking on a Thursday or Friday: Because the skin test must be read within 72 hours, getting an injection on a Thursday afternoon often means the reading window falls on a Sunday when the retail clinic might be closed. Schedule your placement early in the week (Monday or Tuesday).
- Scratching or Covering the Injection Site: Don't scratch, pick at, or put tight adhesive bandages over the PPD wheal. Normal washing is fine, but keep the area gentle and undisturbed.

Frequently Asked Questions
Can I walk into Walgreens without an appointment for a TB test?
While some locations accept walk-ins depending on daily clinician availability, booking an appointment online through the Walgreens health portal is strongly recommended to guarantee you are seen within operating hours.
What happens if my TB skin test is positive?
A positive skin test does not automatically mean you have active, contagious tuberculosis disease. It indicates you have been exposed to the bacteria at some point. You will need a follow-up chest X-ray and a medical evaluation through a primary care doctor or local health department to rule out active infection.
Will insurance cover a TB test for employment?
Coverage varies wildly by provider and employer plan rules. Some insurance plans classify occupational screenings as a mandatory out-of-pocket expense unless explicitly ordered by a primary physician for diagnostic medical reasons rather than administrative compliance.
Does the TB skin test hurt?
You will feel a brief pinch and sting as the PPD solution is injected intradermally, followed by temporary localized itching as a small bump forms. The discomfort subsides within minutes.
