How to Schedule a TB Test at CVS

What you need to know about getting a TB test at CVS

CVS MinuteClinic locations offer tuberculosis (TB) skin tests, also called Mantoux tests or purified protein derivative (PPD) tests. You can walk in without an appointment at most locations, though scheduling ahead online or by phone usually means a shorter wait. The test itself takes about five minutes — a nurse injects a small amount of TB protein under your skin on your forearm — but you'll need to return 48 to 72 hours later so the nurse can read the results.

The cost varies by location and whether you have insurance, but uninsured patients typically pay $30 to $50 for the initial injection and reading combined. If you have insurance, your copay or coinsurance applies. Some CVS locations may not offer TB testing, so it's worth checking availability at your nearest store before you go.

Key Takeaways

• TB tests at CVS require two separate visits: one for the injection and one 48 to 72 hours later for the reading, and both must happen at the same location.
• You can walk in without scheduling, but calling ahead or booking online through the CVS website usually reduces wait time.
• Bring a photo ID and insurance card if you have one; the nurse will ask about your medical history and any previous TB tests.
• If you're allergic to latex, tell the staff when you arrive, as the test involves a needle and sometimes a bandage.
• A positive or indeterminate result does not mean you have active TB disease — it means you need a follow-up chest X-ray, usually ordered by your doctor.

How to schedule your TB test appointment

Start by visiting the CVS website and searching for MinuteClinic locations near you. Click on the location and scroll to "Services offered" to confirm TB testing is available. If you want to schedule in advance, select "Schedule an appointment" and choose the TB test option. You'll pick a date and time for your first visit (the injection), and the system will automatically reserve your return slot for the reading.

If you prefer to call, use the store locator to find the MinuteClinic phone number for your location. The staff can tell you wait times and book both appointments over the phone. Walk-ins are accepted at all MinuteClinic locations, but you may wait 30 minutes to an hour depending on how busy the clinic is that day.

What to bring and what to expect at your first visit

Bring a photo ID (driver's license, passport, or state ID) and your insurance card if you have one. The nurse will ask you several questions: whether you've had a TB test before, if you've ever been exposed to someone with TB, whether you have symptoms like a persistent cough or night sweats, and if you've traveled to countries where TB is common. Answer honestly — this information helps the nurse interpret your results correctly.

Wear loose, short-sleeved clothing or something you can roll up easily, since the injection goes on your inner forearm. The nurse will clean a small area of skin with alcohol, then inject the TB protein just under the surface. You'll see a small raised bump (called a wheal) appear immediately — this is normal and expected. The whole process takes about five minutes. You don't need to do anything special after the injection; you can go about your day normally.

The 48 to 72 hour wait and your second appointment

Your second appointment is scheduled automatically when you book the first one. It must happen between 48 and 72 hours after your injection — not before, not after. If you scheduled online, you'll receive a confirmation with both appointment times. If you walked in or called, ask the nurse to write down your return date and time before you leave.

Mark your calendar and set a phone reminder. If you can't make your scheduled reading time, call the MinuteClinic location as soon as possible to reschedule. Missing the window means the test is invalid and you'll have to start over with a new injection.

How the TB test result is read and what it means

At your second visit, the nurse will measure the size of the bump on your forearm using a ruler. The measurement is given in millimeters. A result is considered positive, negative, or indeterminate based on the size of the bump and your risk factors for TB. The nurse will tell you the result on the spot.

A negative result means you don't have TB infection. A positive or indeterminate result does not mean you have active TB disease — it means your immune system has been exposed to TB bacteria at some point. You'll need a chest X-ray to determine whether you have active TB or latent TB infection (where the bacteria are in your body but not making you sick). The MinuteClinic nurse will give you a form to take to your doctor or a local health department clinic to arrange the X-ray.

Cost and insurance coverage

Without insurance, expect to pay $30 to $50 total for both the injection and the reading. Some CVS locations charge per visit rather than as a package, so the cost might be split between your two appointments. If you have health insurance, your copay typically ranges from $0 to $50 depending on your plan. Call your insurance company or check your plan documents to find out what you'll owe.

If you're uninsured and cost is a concern, ask the MinuteClinic staff whether your local health department offers free or low-cost TB testing. Many do, though the wait may be longer than at CVS.

What to do if you test positive

A positive TB test result means you need a chest X-ray to see whether you have active TB disease or latent TB infection. The MinuteClinic will give you a referral form. Take it to your primary care doctor, an urgent care clinic, or your local health department — all can order the X-ray. If you have symptoms like a persistent cough, fever, or night sweats, tell your doctor right away; don't wait for the X-ray appointment.

Latent TB infection is not contagious and doesn't make you sick, but it can turn into active TB disease later in life. Your doctor may recommend preventive medication. Active TB disease is contagious and requires treatment with antibiotics for several months. Either way, the next step is always a conversation with your doctor, not a decision you make based on the skin test alone.

Frequently Asked Questions

Can I get a TB test at any CVS location?

TB tests are offered at CVS MinuteClinic locations, not at the pharmacy counter. Not every CVS has a MinuteClinic, so check the store locator on the CVS website and confirm TB testing is listed under services before you go.

What if I miss my second appointment for the reading?

The reading must happen between 48 and 72 hours after the injection. If you miss that window, the test is invalid and you'll need a new injection. Call the MinuteClinic as soon as you realize you'll be late and ask if they can fit you in before the window closes.

Do I need a doctor's order to get a TB test at CVS?

No. MinuteClinic offers TB tests without a referral or doctor's order. You can walk in or schedule on your own. If your doctor ordered the test, bring the order with you, but it's not required.

What if I'm pregnant or breastfeeding — is the TB test safe?

The TB skin test is considered safe during pregnancy and while breastfeeding because it doesn't involve a live vaccine. Tell the nurse you're pregnant or breastfeeding so she can note it in your record, especially if your result is positive and you need follow-up testing.

Can I shower or bathe between my two appointments?

Yes. You can shower, bathe, and get the injection site wet without affecting the test. Just don't scratch or rub the bump, and try not to cover it with a tight bandage or clothing that irritates the skin.
