TB Testing and Rehab Admission

You are afraid a TB test will keep you out of treatment. Ask which test, who reads it, and what happens if the result is still pending.

Need help with this? Talk to someone now. Free and confidential. For you, or for someone you're worried about.

Key takeaway

You are afraid a tuberculosis test will close the door, or that a positive line means you are contagious. Block-grant programs must offer TB counseling, testing, and referral. A positive test usually means infection and needs more evaluation. Tonight, ask which test this program uses and what happens while you wait.

You are afraid a tuberculosis test will keep you out of treatment, or that a positive line means you are contagious in the group room. Often the test is a funding rule at some programs, and a positive result still needs a clinician, not a closed door.

If you cannot breathe, are coughing blood and collapsing, or will not wake, call 911. For a mental health crisis, call or text 988.

Ask which test, and what happens while you wait

Programs that receive substance use block-grant funds must make tuberculosis counseling, testing, and referral available to each person in treatment. The program can provide the services or arrange them with another public or nonprofit provider. If it lacks capacity and turns someone away who needs TB treatment, it is supposed to refer that person to another provider of those services. A private program that does not receive those funds is outside that rule. Tonight, ask whether this program uses the funds, which test it requires, who reads it, and whether you can start the rest of care while a result is pending.

A blood test needs one visit. A skin test is read by a trained worker 48 to 72 hours later. The blood test is preferred for people age 5 and older who received the BCG vaccine. Do not score the spot yourself. If you already have written proof of a previous positive result or of treatment for TB disease, bring the paper. Most people who were positive stay positive, and another test usually does not help.

The wider exam before detox and what happens on day one are separate from this test. A urine drug screen does not diagnose TB. Do not stop a prescribed medicine so a file looks simpler. What to bring includes that list.

A positive test is infection until a clinician says more

A positive blood or skin test usually means infection. Inactive TB, also called latent infection, has no symptoms and cannot be spread. Without treatment it can become active disease. The evaluation can include a chest radiograph. Some people with TB disease have a negative test, so symptoms should not wait on the line.

A bad cough lasting 3 weeks or longer, chest pain, or coughing up blood or sputum can be active disease in the lungs. Weakness, weight loss, fever, and night sweats can come with it. Contact a clinician or the local health department. Active disease is reported to public health. That report is not permission for a program to tell your employer you are in substance use treatment. Privacy rules cover the treatment record.

Common Questions

Does every rehab have to give me a TB test before I walk in?

Not as a rule for every private program. Programs that receive substance use block-grant funds must make tuberculosis services routinely available to each person in treatment, directly or through another public or nonprofit provider. Those services are counseling, testing, and referral for medical evaluation and treatment. A program that does not receive those funds is outside that sentence. Ask this program what it requires.

What are the two tests CDC describes?

A TB blood test, also called an IGRA, uses one blood draw. A TB skin test, also called a Mantoux or PPD test, is read by a trained health worker 48 to 72 hours later. The blood test is preferred for people 5 and older who received the BCG vaccine. The skin test is an acceptable alternative when a blood test is unavailable, too costly, or too burdensome. Do not read the spot yourself.

Does a positive test mean I have active TB and cannot be admitted?

A positive blood or skin test usually means TB infection. More evaluation, including a chest radiograph, is needed to rule out TB disease. Inactive TB, also called latent infection, causes no symptoms and cannot be spread. It can become active disease later if it is not treated. Some people with TB disease have a negative test, so symptoms should not wait on that result.

Which symptoms should not wait?

Active TB in the lungs may cause a bad cough lasting 3 weeks or longer, chest pain, or coughing up blood or sputum. Other symptoms include weakness or fatigue, weight loss, loss of appetite, chills, fever, and night sweats. Contact a clinician or the local health department and ask about testing. If you are coughing blood and you cannot breathe, or you collapse, call 911.

How is this different from a urine drug screen?

A urine screen is a clinical check for substance use during treatment. Tuberculosis testing is a separate infectious-disease question. A drug screen does not diagnose TB, and a TB test does not prove abstinence. Neither result is a reason to stop a prescribed medicine on your own. Bring the list of medicines you already take.
