Which TB Test Do You Need in Tucson?

Choosing the right TB test comes down to three questions: 

Can you come back for a second visit? Have you ever had a BCG vaccine, and how fast do you need to be cleared?

​

If returning 48 to 72 hours after placement is easy, the PPD skin test is the simplest and most economical option — just note that we do not place skin tests on Thursdays, since the reading would come due on a closed weekend. If a second trip is hard to fit in, the QuantiFERON Gold blood test settles everything in a single draw.

​

If you have ever received a BCG vaccine, a skin test can read as a false positive. QuantiFERON Gold is not affected by BCG, so it gives you a cleaner, more reliable result.

​

If your job, school, or program specifically calls for the 2-step PPD—common across many healthcare, caregiving, and program entries because it can reveal an older infection a single test might overlook—plan ahead, since the two placements are

 one to three weeks apart.

When a deadline is tight, QuantiFERON Gold is the fastest route to a documented result: no return visit, with lab results back in 48 to 72 hours.

Please note: PPD skin tests are not placed on Thursdays. The reading has to happen 48 to 72 hours after placement, and a Thursday placement would come due on the weekend when we are closed.

This applies to the single PPD and to both steps of the 2-step test. The QuantiFERON Gold blood test has no return reading, so it can be done any business day, including Thursday.

TB Testing FAQ

What does a positive TB test mean? A positive result means you have likely been exposed to TB at some point — not that you have active, contagious tuberculosis. Most positives are latent, meaning the bacteria are inactive. The next step is follow-up with a provider, usually a chest X-ray, to confirm whether any active infection is present.

Do I have to come back to get my skin test read? Yes — that return visit is required for a PPD. The injection has to be examined and measured by our clinical staff 48 to 72 hours after placement; a skin test read too early or too late isn't valid. If a single visit suits your schedule better, the QuantiFERON Gold blood test gives you clearance with no return trip at all.

How long is a TB test good for? Most employers, schools, and programs accept TB clearance for one year from the test date, though some settings require testing more often and others accept a recent baseline. Check what your specific form or policy states. If you need a fresh test or an annual renewal, we can run whichever version your requirement calls for.

Do you take insurance for TB testing? No — Quick Test is a direct-pay lab, so we do not bill insurance. That keeps pricing flat and your visit fast. We also accept FSA/HSA.
