Facilities may require different types of TB screenings and have specific documentation standards. Below are the most common tests and what to expect:
PPD (Tuberculosis Skin Test):
A small amount of purified protein derivative (PPD) is injected under the skin of your forearm. The test must be read in person 48–72 hours later.
Negative: No swelling or induration.
Positive: Swelling or induration of 5–9mm.
Note: This test requires two visits to the clinic.
Quantiferon (QFT-Gold):
A blood test that measures your immune system's T-cell response to Mycobacterium tuberculosis.
Requires a blood draw
Typically takes several days to result
T-SPOT:
Another blood test that measures sensitized T-cells in response to TB infection.
Requires a blood draw
Typically results in 24–48 hours
❗Important: If any test comes back positive, a chest X-ray will be required to rule out active TB. This is why it’s crucial to complete your health orders as early as possible.
Once your Compliance Coordinator sets up your Onboarding Checklist, you’ll be able to view the facility’s specific TB screening requirements. Your Coordinator will also reach out via Inbox to send any necessary health orders.
You'll take these orders to a clinic to complete the tests. If the clinic is part of our partner network, you’ll typically receive an invoice and won’t need to pay out of pocket. If you are required to pay upfront, you can submit a reimbursement request for eligible expenses.
