A tuberculosis test is used to determine whether a person has been infected with the bacteria that cause tuberculosis, also called Mycobacterium tuberculosis.
A person can have TB infection without feeling sick. This is commonly referred to as latent or inactive TB infection. People with inactive TB generally do not have symptoms and do not spread TB to others. Active TB disease is different and can cause symptoms and may be contagious when it affects the lungs.
TB testing is therefore not only for people who feel sick. Testing may also be recommended or required for people who have been exposed to TB, have certain risk factors, or need documentation for employment, school, healthcare training, travel, or immigration.
Many people search for a TB test in Las Vegas because they need documentation for a specific requirement.
Depending on the organization and your individual circumstances, TB screening may be requested for:
If you are getting tested for a specific requirement, bring any instructions or forms provided by your employer, school, program, or organization. Requirements can differ, so it is important to know which type of test and documentation they require.
There are two main types of tests used to detect TB infection:
The appropriate test depends on factors such as your medical history, previous TB testing, vaccination history, exposure risk, age, and the requirements of the organization requesting the test.
The TB skin test is also called the Mantoux test or PPD test.
During the test, a small amount of purified protein derivative is placed just under the skin of the forearm. A trained healthcare professional then reads the reaction after the required waiting period.
A TB skin test requires a return visit. The test should be read between 48 and 72 hours after placement.
If you are searching for a PPD test in Las Vegas, ask the organization requesting your screening whether a TB skin test is the specific test they require.
A TB blood test is known as an interferon-gamma release assay, or IGRA.
The test uses a blood sample to determine whether your immune system reacts to TB-related proteins.
TB blood testing may be particularly useful for people who received the BCG vaccine because TB blood tests are not affected by BCG vaccination in the same way that a TB skin test can be.
Commonly available IGRA tests include QuantiFERON-TB Gold Plus and T-SPOT.TB.
If your employer, school, healthcare program, or other organization specifically requires a TB blood test, confirm the required test before coming to the clinic.
Not every person needs the same TB test.
| TB Skin Test | TB Blood Test |
|---|---|
| Also called TST, PPD, or Mantoux | Also called IGRA |
| Uses a small amount of testing material under the skin | Uses a blood sample |
| Requires a return visit for reading | Blood is collected during one visit |
| Result is read after 48–72 hours | Laboratory processing is required |
| Can be affected by previous BCG vaccination | Not affected by BCG vaccination |
| Often used for routine screening | May be preferred for people who received BCG |
Your healthcare provider can help determine which testing method is appropriate for your situation.
If you receive a TB skin test, the process generally involves two visits.
During your first visit, a small amount of PPD is injected into the skin of the forearm.
The procedure takes only a short time.
You must return to the clinic 48–72 hours after placement so a trained healthcare professional can examine and measure the reaction.
This follow-up visit is an important part of the TB skin-testing process.
If you cannot return within the required timeframe, contact the clinic for instructions because the test may need to be repeated.
A TB blood test requires a blood sample.
Unlike a skin test, an IGRA does not require a patient to return 48–72 hours later for the test to be read. The blood sample is processed by a laboratory, and the turnaround time depends on the laboratory and test being performed.
If you are considering a TB blood test, ask about availability, processing time, and the documentation you need for your employer or school.
TB testing may be appropriate for people who:
You may need TB testing even if you feel completely healthy because inactive TB infection usually does not cause symptoms.
If you have recently spent time with someone who has active TB disease, contact a healthcare professional about whether testing is appropriate.
The timing of testing can matter after a recent exposure. Your healthcare provider may recommend an initial test and, depending on the circumstances, additional evaluation or repeat testing.
If you have symptoms that could indicate active TB disease, do not rely on a screening test alone. A medical evaluation may include a physical examination, TB testing, chest X-ray, and other laboratory testing when appropriate.
A positive TB skin test or TB blood test does not by itself establish whether you have active TB disease.
A positive result generally means that TB infection needs further evaluation.
Depending on your circumstances, a healthcare professional may recommend:
If you have a positive result, follow the healthcare professional’s recommendations for appropriate follow-up.
TB skin and blood tests are primarily used to identify TB infection. They cannot by themselves determine whether an infection is latent/inactive or active TB disease.
If you have symptoms of active TB disease or receive a positive TB test, additional medical evaluation may be needed.
Symptoms of active pulmonary TB can include:
If you have concerning symptoms, speak with a healthcare professional rather than relying only on a screening test.
Healthcare workers and students entering healthcare programs may have specific TB screening requirements.
Depending on the employer, facility, school, or applicable requirements, screening may involve a TB skin test or an IGRA blood test. Some healthcare personnel may also be required to complete two-step TB skin testing.
Nevada’s healthcare-facility TB screening guidance addresses TB screening requirements for healthcare workers, including two-step TST or IGRA testing in applicable circumstances.
If you are completing a healthcare program or beginning a healthcare job in Las Vegas, bring the testing instructions supplied by your school or employer so the appropriate testing and documentation can be arranged.
Students may need TB testing before entering certain healthcare, nursing, medical, education, or other programs.
Your school may specify:
Because requirements vary between programs, check your school’s instructions before testing.
Some employers require TB screening before employment or periodically as part of occupational health requirements.
If you need a TB test for work in Las Vegas, bring your employer’s testing instructions and any required paperwork.
This can help make sure the test and documentation match your employer’s requirements.
The BCG vaccine is commonly used in countries where TB is more common.
If you have received BCG vaccination, tell your healthcare provider before TB testing.
The CDC notes that TB blood tests are preferred for people who have received BCG because BCG vaccination can cause a false-positive TB skin test result, while TB blood tests are not affected by BCG vaccination.
Your healthcare provider can help determine which test is most appropriate for your circumstances.
The time depends on which type of TB test you receive.
The placement itself is quick, but the process requires a second visit 48–72 hours later for the result to be read.
A blood sample is collected during the visit and sent for laboratory processing. Results depend on the specific laboratory and test.
If you need your results by a particular date for work or school, ask about expected turnaround time before testing.
A TB skin test involves a small injection into the skin of the forearm. Most people experience only brief discomfort during placement.
You may notice a small area of swelling or irritation at the injection site. The reaction is evaluated by measuring induration rather than simply looking at redness.
If you have questions about what you should expect after the test, ask your healthcare provider.
