A 2-step TB test in Tucson is two PPD skin tests placed one to three weeks apart — the standard many hospitals and healthcare programs require for new staff and students. Walk-ins welcome.

Why Two Placements Give a More Accurate Result
If you were exposed to TB long ago, your immune system can respond weakly to a single skin test and read negative when it should not. The first placement reminds your immune system of that earlier exposure, and the second — set one to three weeks later — elicits a stronger, more accurate response. That pattern is why hospitals, nursing programs, home health agencies, and long-term care employers ask for it as your baseline screening.
Each visit takes about 15 minutes from the time you sit down, and your first placement can happen the same day you walk in.
Your 2-Step TB Skin Test Timeline in Tucson
Plan for four short visits across one to three weeks.
Visit 1—Day one. Walk in, and we place your first PPD; it takes about 15 minutes from start to finish.
Visit 2 — 48 to 72 hours later. We read and document the results of that first placement, both when it is placed and when it is read.
Visit 3 — One to three weeks after Visit 1. We place your second PPD.
Visit 4—48 to 72 hours after Visit 3. We read the second placement and hand you signed documentation for your employer, school, or compliance portal.
Because each reading has to land on a day we are open and we are closed weekends, we do not place TB skin tests on Thursdays—that keeps your reading off the weekend.
Who Needs a 2-Step TB Test in Tucson?
The 2-step is almost always a first-time, baseline requirement rather than an annual one. You'll usually be asked for it when starting a healthcare or caregiving job, entering a nursing or allied-health program, or onboarding with a hospital, home health agency, or long-term care facility. Once your baseline is on file, most employers and schools only require a single TB test each year after that. We place 2-step tests for people across Tucson, Marana, Oro Valley, Catalina Foothills, Sahuarita, and Vail, with documentation formatted for upload to school and employer portals.
2-Step TB Skin Test FAQ
Do I need a 2-step TB test every year? No. The 2-step is a one-time baseline, usually required only when you first start a job or program. After it's documented, most employers and schools accept a single annual TB test going forward — either a one-step PPD or a QuantiFERON Gold blood test — rather than repeating the full series each year.
Do you take insurance for the 2-step TB test? No — Quick Test is a direct-pay lab, so we do not bill insurance. That keeps your pricing flat and visits fast, with no claims or referrals to wait on.
Can I switch to the blood test if four visits won't fit my schedule? Yes. If the multi-week schedule is a problem, the QuantiFERON Gold blood test meets the same requirement in one visit, with no return reading and results in 48 to 72 hours. Confirm your employer or school accepts a blood test in place of the 2-step—most do—and we can draw it the same day.
