Understanding TB Testing: What You Should Know

Tuberculosis (TB) is a serious infection caused by bacteria that spreads through the air when a person with TB coughs, sneezes, or speaks. Understanding TB testing is an important part of public health. According to the CDC, about 7,000 cases of TB were reported in the United States in 2022. While this number has been declining for decades, TB remains a concern in certain populations and geographic areas.

TB testing detects whether someone has been infected with the TB bacteria. There are two main types of TB tests: the tuberculin skin test (TST), also called the Mantoux test, and blood tests that detect TB infection. The skin test involves injecting a small amount of purified protein derivative (PPD) under the skin on the forearm. A healthcare provider then checks the injection site 48 to 72 hours later to see if a reaction has occurred. Blood tests, including interferon-gamma release assays (IGRAs), measure how a person's immune system reacts to TB antigens.

People seek TB testing for different reasons. Some have symptoms like persistent cough lasting more than three weeks, chest pain, coughing up blood, fever, chills, or night sweats. Others may have been exposed to someone with active TB disease. Healthcare workers, people in correctional facilities, and those living in congregate settings often receive regular TB screening. Immigrants and refugees from countries where TB is common are also frequently tested.

The difference between TB infection and TB disease matters. TB infection means a person has been exposed to and carries the TB bacteria, but the bacteria are inactive and the person is not sick. TB disease occurs when the bacteria become active in the body, causing illness and symptoms. Only people with TB disease are contagious.

Takeaway: Learning why TB testing exists and how it works helps you understand what to expect if you decide to seek testing. Knowing the difference between TB infection and TB disease can also help you have better conversations with healthcare providers.

Where to Find TB Testing in Your Community

TB testing is available through many different locations and organizations across the United States. Health departments in every state and most counties operate TB control programs. These public health agencies provide TB testing and treatment services, often at no cost or low cost to patients. To find your local health department, you can search online using your county or city name plus "health department" or visit the CDC website, which maintains links to state health departments.

Community health centers offer TB testing as part of their primary care services. Federally Qualified Health Centers (FQHCs) are located in medically underserved areas and serve uninsured and low-income populations. You can search for FQHCs near you on the Health Resources and Services Administration website. These centers typically provide testing on a sliding fee scale based on income.

Hospitals and urgent care clinics throughout the country provide TB testing. Many people can walk in or call to schedule an appointment. If you have health insurance or a relationship with a primary care doctor, your regular healthcare provider can order TB testing and arrange for you to receive it. Private labs that perform TB blood tests sometimes offer testing at retail locations, which may be convenient for those who prefer walk-in services.

Workplace TB testing is common in certain industries. Healthcare facilities, nursing homes, schools, and prisons typically conduct TB screening for staff members and residents. Your employer may have information about how to receive testing through occupational health services.

Special populations have targeted TB testing resources. Immigration services sometimes require TB testing for visa applicants and refugees. International adoption agencies often arrange pre-arrival TB testing. Travel clinics can perform TB testing for people planning travel to high-risk countries. Homeless shelters and substance use disorder treatment programs frequently offer TB testing to their clients.

Takeaway: Start by identifying which type of location is most convenient for you—whether that's your local health department, your primary care doctor, a community health center, or a walk-in testing site. Different locations have different hours and services, so calling ahead is usually wise.

How to Locate and Contact TB Testing Services

Finding TB testing services in your area requires knowing which resources to contact. The most direct approach is calling your county or local health department. Health department TB clinics are specifically designed to test and treat TB and typically have staff experienced with TB-related questions. When you call, ask specifically for the TB control program or TB clinic. You can locate your health department's phone number by searching online for "[your county] health department" or visiting your state health department's website.

The CDC maintains a website with links to TB resources organized by state. This can help you connect to your state's TB program, which can then direct you to local testing sites. Some states have dedicated TB hotlines that answer questions and provide referrals to testing locations. The National TB Hotline, operated by the CDC, can also provide general information and referrals. Their number is 1-800-232-4636, and they can help direct you to services in your area.

Finding FQHCs requires using the official search tool on the HRSA website. You can search by entering your zip code and selecting "find a health center." Once you've identified centers near you, call to ask about TB testing availability and hours. Many FQHCs have websites listing their services and phone numbers for scheduling.

If you have health insurance, your insurance company's website or customer service line can help you locate in-network providers offering TB testing. You can also call your primary care doctor's office and ask about TB testing options. Hospitals often have scheduling lines where you can request a TB test through their laboratory or occupational health department.

Online directories for urgent care clinics, retail pharmacies offering testing services, and walk-in labs allow you to search by location and see hours of operation. Many of these services show pricing information upfront, which can help you compare options.

Takeaway: Keep a list of 2-3 testing locations and their phone numbers. This gives you backup options if your first choice is unavailable or has a long wait time. Write down your symptoms or reason for seeking testing so you can clearly explain this to whoever answers your call.

Understanding Costs and Payment Options for TB Testing

The cost of TB testing varies significantly depending on the type of test and where you receive it. Public health department TB clinics provide testing at no cost or very low cost to patients, regardless of insurance status. This is a fundamental part of TB control efforts, since identifying and treating TB cases benefits everyone in the community. If you're uninsured or have concerns about cost, health department clinics are typically your most affordable option.

Private healthcare providers' costs for TB testing depend on your insurance coverage and the facility. A tuberculin skin test through a private doctor typically costs between $15 and $50 for just the injection and reading fee, though your insurance may cover part or all of this. Blood tests for TB detection cost more, ranging from $50 to $200, depending on the specific test and facility. If you have health insurance, your cost may be much lower because of your plan's negotiated rates. Some insurance plans cover TB testing with no patient cost-sharing when ordered by your doctor as preventive care.

Federally Qualified Health Centers use sliding fee scales based on your household income and size. This means you pay what you can afford. Uninsured patients with low incomes often pay nothing or a very small fee. Centers receive federal funding to provide services regardless of a patient's ability to pay.

If you're concerned about cost, always ask about payment options before you go for testing. Health department clinics can tell you immediately that testing is free. Community health centers can discuss your income situation to determine your fee. Private facilities often offer payment plans or discounts for uninsured patients who ask. Some pharmaceutical assistance programs also help with costs for TB-related medical care.

Workplace TB testing is typically covered by your employer at no cost to you. Immigration-related TB testing fees vary but are sometimes included in visa or adoption fees, or may be covered by the immigration service or adoption agency.

Takeaway: Don't avoid getting TB testing because of cost concerns. Call 2-3 locations and ask about their pricing structure. If cost is a barrier, your local health department TB clinic should be able to test you at minimal or no charge.
