What Happens If Your TB Test Is Positive? Next Steps in Torrance, CA

March 26, 2026

If you’ve just been told your TB test is positive, it’s completely normal to feel concerned.


One of the most common questions people ask is:


“Does this mean I have tuberculosis?”


The short answer: Not necessarily.


A positive TB test does not automatically mean you have active tuberculosis disease. In most cases, especially in workplace or school screenings, it means you may have been exposed to TB bacteria at some point in your life.


At Lifeline Walk-In Clinic in Torrance, CA, we provide walk-in TB testing and can guide you through next steps if your result is positive.

What Does a Positive TB Test Actually Mean?


A TB test — whether a skin test (PPD) or blood test (IGRA) — checks whether your immune system has been exposed to tuberculosis bacteria.


If your result is positive, it means:

  • Your body recognizes TB bacteria.
  • You were likely exposed at some point.
  • Further evaluation is needed.


It does not automatically mean:

  • You are sick.
  • You are contagious.
  • You cannot work or attend school.


The next step is determining whether you have latent TB or active TB.


Latent TB vs. Active TB


Understanding the difference is important.


Latent TB Infection (Most Common)


Latent TB means:

  • You have TB bacteria in your body.
  • You do not feel sick.
  • You have no symptoms.
  • You are not contagious.


Most people with a positive TB test have latent TB.


In many work or school situations, clearance can still be granted after additional evaluation confirms there is no active infection.


Active TB Disease (Less Common)


Active TB means:

  • You have symptoms.
  • The bacteria are actively multiplying.
  • You may be contagious.
  • Treatment is required.


Common symptoms of active TB include:

  • Persistent cough
  • Fever
  • Night sweats
  • Weight loss
  • Fatigue


If you do not have these symptoms, active TB is less likely — but evaluation is still required.


Do You Need a Chest X-Ray After a Positive TB Test?


In California, many employers and schools require a chest X-ray after a positive TB test.


The purpose of the chest X-ray is to:

  • Check for signs of active tuberculosis.
  • Confirm that you are not contagious.
  • Provide documentation for clearance.


If the chest X-ray is normal and you have no symptoms, you are typically considered to have latent TB.


This process is very common in California, especially in healthcare and school settings.


Can You Work or Go to School with a Positive TB Test?


In most cases — yes.


If evaluation confirms you have latent TB and not active TB:

  • You are not contagious.
  • You can usually work or attend school.
  • Clearance documentation can often be provided.


Each employer or institution may have specific requirements, so bringing your paperwork to your visit is helpful.


What If You Previously Tested Positive?


If you have had a positive TB test in the past:

  • You should not repeat a skin test.
  • A blood test may not be necessary if documentation is available.
  • Employers often require documentation of prior chest X-ray results.


Bring previous records if possible to avoid unnecessary repeat testing.


Do You Need Treatment for Latent TB?


Treatment decisions for latent TB depend on several factors, including:

  • Age
  • Risk factors
  • Immune system health
  • Healthcare provider recommendations


Some individuals may be advised to take medication to reduce the risk of developing active TB in the future.


Your provider can discuss whether treatment is recommended in your situation.


How Long Does the Follow-Up Process Take?


The timeline depends on:

  • When your positive test result is identified
  • Scheduling of chest X-ray
  • Employer or school documentation requirements


In many cases:

  • The TB test result is known quickly
  • A chest X-ray is completed soon after
  • Clearance documentation follows once active TB is ruled out


Planning early helps avoid delays in employment or school start dates.


Common Reasons for Positive TB Tests in California


A positive TB test may occur because:

  • You were exposed years ago without knowing it
  • You traveled to or lived in a country with higher TB rates
  • You received the BCG vaccine (skin test may react)
  • You work in healthcare or community settings


In many cases, exposure happened long ago and never caused illness.

When Should You Seek Immediate Care?


While most positive TB tests represent latent infection, seek medical evaluation promptly if you experience:

  • Persistent cough
  • Fever
  • Night sweats
  • Unexplained weight loss
  • Fatigue


These may be signs of active TB and require further medical attention.


Reassurance: A Positive TB Test Is Common


It’s important to remember:

  • Many people in California have positive TB tests due to prior exposure.
  • Most do not have active TB.
  • Proper evaluation allows you to continue working or attending school safely.


If you’re unsure what your result means, a provider can walk you through the process clearly and calmly.

Public Health Ending Clinic Services at 7 Locations Due to Funding Cuts

February 25, 2026
LOS ANGELES — The Los Angeles County Public Health Department is ending clinical services at seven of its 13 locations throughout the county. What You Need To Know Cuts result from significant fiscal challenges because of a more than $50 million cut in federal, state, and local funding According to the County Health Department, federal funding accounts for almost 50% of its budget Due to continued uncertainty, the statement released by the health department noted there could be additional service disruptions going forward The clinics that are stopping services offered things like vaccines and STD testing In a statement released by the health department, it cited significant fiscal challenges because of a more than $50 million cut in federal, state and local funding. Dr. Anulika Chilaka opened Lifeline Walk-in Clinic in Torrance a year ago, and she said privately owned clinics like hers will not be impacted by these cuts. “It is concerning when people are losing access to care. It is always concerning to anyone from a health care standpoint, but we want people to know we are here for you,” said Dr. Chilaka. According to the County Health Department, federal funding accounts for almost 50% of its budget. Because of a more than $50 million cut in federal, state, and local funding, the county will close locations starting on February 27. Due to continued uncertainty, the statement released by the health department noted there could be additional service disruptions going forward. Leaving family-owned clinics like Dr. Chilaka’s filling the gap. “We are open, we don’t have the same restrictions, we can do as much as we can, we can spend as much time with our patients, we can do more than perhaps some other places may be able to,” said Dr. Chilaka. In a statement sent to Spectrum News by LA County Supervisor Kathryn Barger, she said in part: “The Department of Public Health’s decision was based on low patient volume and the clinic’s limited scope of care. I will continue to monitor DPH’s closure plan to ensure patients are fully supported through referrals to nearby community-based clinics and other transition resources so they continue receiving the care they need.” The clinics that are stopping services offered things like vaccines and STD testing. According to the health department, these locations will still offer non-clinical services and programs.
