How to Schedule a PPD Skin Test at Walgreens

What a PPD appointment at Walgreens involves

A PPD (purified protein derivative) skin test at Walgreens is a tuberculosis screening where a nurse injects a small amount of PPD solution under your skin, usually on your forearm. You return 48 to 72 hours later so the nurse can measure any bump or reaction at the injection site. The test itself takes a few minutes each visit, and Walgreens pharmacies with in-store clinics can perform both the injection and the reading.

You do not need a doctor's order to book a PPD at most Walgreens locations, though some require one depending on state law and the specific store's policy. Call your local Walgreens pharmacy ahead to confirm whether they offer PPD testing and whether you need a referral. If your location does not offer it, the pharmacy staff can often direct you to a nearby clinic or urgent care that does.

The cost varies by location and whether you have insurance. Walgreens typically charges between $15 and $30 for the test if you pay out of pocket, though some insurance plans cover it fully or in part. Ask about the price when you call to schedule, and bring your insurance card if you have one.

Key Takeaways

• A PPD test requires two visits to Walgreens: one for the injection and one 48 to 72 hours later for the nurse to read the result.
• Most Walgreens pharmacies do not require a doctor's order, but you should call ahead to confirm your location offers PPD testing.
• The test costs $15 to $30 without insurance, though your plan may cover it partially or fully.
• You will receive a written result at your second appointment, which you can share with your doctor or employer.

How to schedule your first appointment

Call the pharmacy department at your local Walgreens directly rather than using the main customer service line. The pharmacy staff can tell you immediately whether they perform PPD tests and what days and times are available. Have your insurance information ready if you have it, and let them know you need both the injection visit and the follow-up reading appointment.

When you call, ask the pharmacist or technician whether your location requires a doctor's order. Some states and individual Walgreens locations do require one, in which case you will need to contact your primary care doctor or an urgent care clinic to request the order before your appointment. The order is usually a simple one-line note that the provider can fax directly to Walgreens.

Book both appointments at the same time if possible. The pharmacy will schedule your injection visit and automatically reserve your follow-up reading appointment 48 to 72 hours later. Write down both dates and times, or ask if Walgreens will send you a text or email reminder.

What to bring and how to prepare

Bring your photo ID and insurance card to your first appointment. If your location required a doctor's order, confirm with the pharmacy that it has been received before you arrive. Wear a short-sleeved shirt or something you can roll up easily, since the injection goes on your forearm and the nurse needs clear access to that area.

There is no special preparation needed before a PPD test. You can eat and drink normally, take your regular medications, and go about your day. Avoid scratching or covering the injection site between your two visits, as this can affect the reading. If you have a bandage on, the nurse will remove it before measuring the reaction.

If you cannot make your follow-up appointment within the 48 to 72 hour window, call the pharmacy as soon as you know. A reading outside this timeframe may not be accurate, and you may need to repeat the test. Walgreens can usually reschedule you quickly if you call ahead.

What happens during your visits

At your first appointment, the nurse will clean a small area on your forearm with alcohol and let it dry. She will then inject a tiny amount of PPD solution just under the skin using a small needle. You will feel a slight pinch, and a small bump (called a wheal) will appear immediately at the injection site. This bump typically fades within a few hours, but the PPD remains in your skin.

The nurse will mark the injection site with a pen or tell you exactly where it is so you can find it at your follow-up visit. She will give you written instructions on how to care for the site and what to watch for. Do not wash off the mark, and avoid putting lotion, sunscreen, or bandages over the area unless the nurse tells you to.

At your second appointment 48 to 72 hours later, the nurse will examine the injection site and measure any hardness or swelling with a ruler. She will record the measurement in millimeters. A larger reaction may suggest tuberculosis infection, while no reaction or a very small one typically means you do not have TB. The nurse will give you a written result to take home.

Understanding your PPD result

Your result will show a measurement in millimeters of any hardness (induration) at the injection site. The meaning of that number depends on your risk factors and medical history. A measurement of 5 mm or larger is often considered positive, but some people with certain risk factors are considered positive at 10 mm or 15 mm. The nurse will explain what your specific result means.

A positive PPD does not automatically mean you have active tuberculosis. It means your immune system has been exposed to TB bacteria at some point. Your doctor will likely order a chest X-ray to determine whether you have active disease or latent infection. A negative result means no TB exposure was detected.

Keep your written result in a safe place. You may need to show it to your employer, school, healthcare provider, or immigration office. If you lose it, call the Walgreens pharmacy and ask for a copy — they keep records of all PPD tests performed.

What to do if your location does not offer PPD testing

Not all Walgreens pharmacies perform PPD tests. If yours does not, ask the pharmacy staff whether they can refer you to a nearby location that does, or whether they know of an urgent care clinic or community health center in your area that offers the test. Many urgent care clinics can perform PPD testing without an appointment or with a short wait.

Your primary care doctor's office may also offer PPD testing, or they can order it through a lab. This route typically takes longer to schedule but may be covered more fully by your insurance. If you need the test quickly for work or school, urgent care is usually the fastest option.

Frequently Asked Questions

Can I get my PPD result the same day?

No. The test requires two separate visits: one for the injection and one 48 to 72 hours later for the reading. The delay allows time for your immune system to react to the PPD. You cannot get an accurate result on the same day.

What if I miss my follow-up appointment?

Call Walgreens as soon as you realize you have missed it. A reading more than 72 hours after injection may not be reliable, and you may need to repeat the entire test. The pharmacy can usually reschedule your reading within a day or two if you call promptly.

Is a PPD test the same as a TB blood test?

No. A PPD is a skin test; a TB blood test (such as the QuantiFERON-Gold test) is drawn from your arm. Both can screen for TB exposure, but they work differently. Ask your doctor or Walgreens which test you need, as some employers or schools require a specific type.

Do I need a doctor's order for a PPD at Walgreens?

It depends on your state and the specific Walgreens location. Call ahead to ask. If one is required, your doctor or an urgent care clinic can provide it quickly, often by phone or fax.

Will my insurance cover a PPD test at Walgreens?

Many insurance plans cover PPD testing, but coverage varies. Call your insurance company or ask Walgreens when you schedule to find out whether you will owe a copay or if the test is fully covered. Out-of-pocket cost is typically $15 to $30.
