Do Caregivers Need a TB Test, and How Often?
Most licensing states require TB screening before a caregiver's first visit. CDC dropped routine annual tests in 2019; states still set their own intervals.

Yes, in most licensing states. A caregiver must show they are free of active tuberculosis before the first client visit, usually with a skin test (TST) or blood test (IGRA), plus a chest X-ray if the test is positive. How often after that is set by your state. CDC’s 2019 guidance dropped routine annual testing for health care personnel without a known exposure, but Pennsylvania still requires an update every 12 months and California every two years.
What does CDC recommend for health care personnel?
Baseline screening at hire, no routine repeat testing, and testing again only after an exposure. The 2019 update from CDC and the National Tuberculosis Controllers Association, carried on CDC’s current screening pages, applies to “home-based health care and outreach settings,” so it covers home care aides.
| Step | CDC recommendation |
|---|---|
| Baseline, at hire | Individual risk assessment, symptom evaluation, and a TST or IGRA unless there is a documented prior positive |
| Positive result | Chest X-ray and evaluation for TB disease; offer treatment for latent infection |
| Routine repeat | Not recommended at any interval without exposure or ongoing transmission |
| After exposure | Symptom check and test now; if negative, retest 8 to 10 weeks after the last exposure |
| Untreated latent TB | Annual symptom screen, no repeat X-ray unless symptoms appear |
| Every year | TB education for all staff |
CDC says plainly that its recommendations do not override state regulations. Your licensing rule wins.
Which test should you use?
Either works, but the blood test needs one visit and no second step. CDC’s testing page notes a skin test must be read 48 to 72 hours after placement by a trained health care worker, so it takes two appointments. For adults who will be tested periodically, CDC recommends two-step skin testing at baseline: a second test 1 to 3 weeks after a negative first, unless there is a documented result from the past 12 months. An IGRA needs no two-step and is preferred for anyone who had the BCG vaccine, which covers many caregivers born abroad.
Neither test is required for someone with a documented prior positive. They need a risk assessment, a symptom screen and a chest X-ray, or proof of a normal one.
What do states actually require?
Screening before client contact is nearly universal in licensing states. The repeat interval is where they differ.
| State | Rule | Before contact | Repeat |
|---|---|---|---|
| Pennsylvania | 28 Pa. Code 611.56 | Proof of screening dated within the year before start, following CDC guidelines | Update at least every 12 months |
| California | HSC 1796.45 | Exam within 90 days before or 7 days after hire; aide cannot work until clearance is on file | At least every two years after a negative test; none after a documented positive with X-ray |
| Other states | Varies | Often required by licensing rule or Medicaid contract | Annual, risk-based, or none |
Pennsylvania’s rule also covers office staff and contractors who have direct consumer contact, not just aides. California’s requires the home care organization to keep the practitioner’s certificate on file and makes the exam a condition of continuing employment. See California HCA registration and our training requirements tool for your state.
What goes in the caregiver file?
The test date, type, result, who read it, and any X-ray report or clearance letter. If the state sets a repeat interval, record the next due date. For a positive result, keep the chest X-ray report and the clinician’s statement that the person is free of active disease, and do not test again. Treat TB results as confidential health information: store them with other medical records, apart from the general personnel file, and limit who can see them. See credential tracking and the onboarding checklist.
Who pays, and what does it cost the schedule?
The agency, almost always, and the two-visit skin test is the real cost. Paying for a required test is standard practice, and in some states time spent on a required pre-employment exam is compensable. The bigger cost is delay: a two-step skin test can take up to four weeks, a blood test a few days. Agencies that hire for a start date two weeks out use the IGRA and book it on offer day. Build the test into your hiring process so a new caregiver is not sitting unpaid while a shift goes unfilled.
How Caregiver Scheduling handles this
On Growth and up, credentials such as TB clearance are checked when you assign a visit, and an expired credential blocks the assignment before it’s made, so a missed renewal cannot put an aide in a client’s home. $199/month for up to 10 caregivers or $299/month for up to 50, free for 30 days.
FAQ
Do caregivers need an annual TB test? Not under CDC guidance, which recommends baseline screening and testing only after exposure. Some states still require annual or two-year updates, so follow your licensing rule.
Is a two-step skin test required? CDC recommends it at baseline when you use the skin test for people who may be tested again. A blood test needs no second step.
What if a caregiver has a positive test? They need a chest X-ray and a clinician’s clearance that there is no active disease. After that, no repeat tests, just an annual symptom check if latent infection goes untreated.
Who pays for caregiver TB tests? Usually the agency. Check your state’s rules on paying for required pre-employment exams.
