Everything You Need to Know About the TB Skin Test in NYC

Have you been in close contact with someone who has tuberculosis (TB)? Or do you have a weakened immune system and are worried about your risk for TB? If so, getting a TB skin test is a good first step in protecting yourself and your community. In this blog post, we’ll cover everything you need to know about the TB skin test in NYC, including what it is, how it’s done, and where you can get it.

What is a TB skin test?

A TB skin test, also known as a Mantoux test, is a diagnostic tool used to determine if you have been exposed to TB bacteria. The test involves injecting a small amount of purified protein derivative (PPD) into your skin, usually on your forearm. After 48-72 hours, a healthcare professional will examine the injection site for a raised, red bump, known as an induration.

If you have been exposed to TB bacteria, your body will have an immune response, resulting in an induration at the injection site. However, it’s important to note that a positive TB skin test does not necessarily mean you have active TB disease. Further testing, such as a chest X-ray or sputum test, may be needed to confirm a TB diagnosis.

Who should get a TB skin test?

The Centers for Disease Control and Prevention (CDC) recommends that certain people get a TB skin test, including:

  • People who have been in close contact with someone who has active TB disease
  • People with weakened immune systems, such as those with HIV or who are taking immunosuppressive medications
  • Healthcare workers who work in high-risk settings
  • People who live or work in congregate settings, such as prisons or homeless shelters

Q: What should I do if my TB skin test is positive?

A: If your TB skin test is positive, it means you have been exposed to TB bacteria at some point in your life. However, it does not necessarily mean you have active TB disease. Further testing, such as a chest X-ray or sputum test, may be needed to confirm a TB diagnosis. Your healthcare provider will work with you to determine the best course of treatment, which may include antibiotics to prevent the development of active TB disease.

Q: Is the TB skin test painful?

A: The TB skin test involves a small needle prick, which may cause some discomfort or a slight burning sensation. However, most people find the test to be relatively painless and well-tolerated.

Q: How long does it take to get the results of a TB skin test?

A: The results of a TB skin test are typically read 48-72 hours after the injection. You will need to return to the healthcare provider who administered the test to have the results interpreted.

Q: Are there any side effects of the TB skin test?

A: In some cases, the TB skin test may cause a mild allergic reaction, such as redness, swelling, or itching at the injection site. More serious side effects are rare, but may include a severe allergic reaction or a skin infection.

Remember, getting a TB skin test is an important part of preventive care, especially if you are at higher risk for TB.
