Two ways to test for TB

  • PPD skin test (TST) — a small injection under the skin; you return in 48–72 hours to have it read. Often required as a two-step for healthcare and school settings.
  • TB blood test (IGRA / QuantiFERON) — a single blood draw, no return visit needed, and not affected by prior BCG vaccination. Ideal when you can't come back in 2–3 days.

Not sure which one your employer or school requires? Bring the paperwork and we'll match it exactly — and if you need it fast, the blood test gets you cleared without a second trip.

Who needs a TB test

  • Healthcare & senior-care workers — hospitals, clinics, home health, assisted living
  • Food-service & food-processing employees
  • School staff, teachers & volunteers
  • New hires where the employer requires TB clearance
  • Students entering nursing, CNA, and allied-health programs
Testing a whole crew? We set employers up on an account for TB testing, plus titers and respirator fit testing — see occupational health. Call (559) 272-7953.

Documentation you can hand right over

When your test is complete and read, we provide clear documentation of the result that satisfies employer, school, and licensing requirements. Pair it with a pre-employment drug test and knock out your whole onboarding in one visit.

Part of full occupational health

TB testing is one piece of the workforce-health services we provide. We also handle titers (immunity checks), vaccinations, respirator fit testing and audiograms — see occupational health.

Answers

Frequently asked — TB Testing

Do I need to come back for a TB skin test?

Yes — a PPD skin test must be read 48–72 hours after it's placed, so it takes two visits. If you can't return in that window, the single-visit TB blood test (IGRA) is the better option.

What's the difference between the TB skin test and blood test?

The skin test (PPD) is an injection read 2–3 days later; the blood test (IGRA/QuantiFERON) is one blood draw with no return visit and isn't affected by prior BCG vaccination.

How much does a TB test cost?

TB skin tests start around $35; the TB blood test costs more due to lab processing. We'll confirm the exact price before you come in.

Can you test my whole staff for TB?

Yes. We set employers up on an account for TB testing along with titers and respirator fit testing for your whole staff.

Do you provide documentation for my employer or school?

Yes. We provide clear result documentation that satisfies employer, school, and licensing requirements.
