TB Testing for Work and School

Why employers and schools require TB testing

TB screening is a common requirement for jobs and programs where people are in close contact for long periods. Health care settings, schools, childcare centers, and congregate living facilities often ask for proof of screening before a start date. The goal is to find any TB infection early and to protect both staff and the people they serve.

Requirements vary. Some organizations accept a recent negative result, while others ask for testing within a set window before you begin. Ask your employer or school exactly which test they accept and how recent the result must be.

Which TB test is usually used

Two screening options are widely used, and both can satisfy most requirements.

The blood test is often preferred because it needs only one visit and is not influenced by BCG vaccination, which many people outside the United States have received. Some settings still use the skin test, so confirm what your organization accepts.

Who typically needs TB clearance

Requirements differ by role and location, but these groups are often asked to test:

• Hospital and clinic staff, including students in clinical rotations
• Childcare and school employees and volunteers
• Nursing home and long-term care workers
• First responders and public safety personnel
• Correctional and shelter staff
• Anyone newly arriving from or traveling to higher-risk regions for a program

If you are unsure whether your role requires testing, your employer or school health office can confirm the policy.

How to order and where to get tested

Self-pay testing lets you order a TB blood test online and visit our partner lab, a CLIA-certified lab, for a blood draw. Most states do not require a separate office visit to order. You pay a set price up front and receive confidential results in a secure account, which you can print or share with your employer or school.

Bring a photo ID and, if your organization provides one, their screening form. The blood test needs only one visit. If a skin test is required instead, plan for a second visit so the site can be read within the correct time window.

How much does TB testing cost

Self-pay TB blood testing commonly costs about $80 to $200, depending on the lab and your location. A skin test is often cheaper, but it requires a return visit for the reading, which can add travel and time off work.

Some employers and schools cover the cost, so ask about reimbursement before you pay. If you pay yourself, confirm the total before ordering. Pricing is fixed and does not depend on your insurance status.

How to prepare and how long results take

No fasting is needed for a TB blood test. The blood draw takes only a few minutes. Results are usually available within two to five business days, and you can share them directly with the organization that requested them.

If a skin test is used, the reading must be done within a specific window, often two to three days after placement. Missing that window means the test may need to be repeated.

Handling a positive result at work or school

A positive TB screening result does not automatically mean you have active TB disease. Most positive screens reflect a latent infection that cannot be spread to others. A clinician will typically check for active disease with a physical exam, imaging, or other tests before clearing or referring you.

Report the result to your employer or school health office as directed. In most cases a documented follow-up plan is enough to satisfy the requirement. Some organizations also accept a signed declination form for people who decline testing, though this varies by policy. If you have a history of a positive TB test, the health office may ask for documentation of prior follow-up instead of a new test. Keeping your records in one place saves time when a new job or program asks for proof. Results can be shared securely online, so you do not need a second trip to pick up paperwork.
