If you live in New York City, you may be wondering if you should get a tuberculosis (TB) test. TB is a serious bacterial infection that can affect the lungs, but it can also affect other parts of the body. It’s important to get tested if you think you may have been exposed to TB or if you have symptoms such as coughing, chest pain, or fever.
At Nao Medical, we offer a 2-step PPD test for TB. This test is more accurate than a single PPD test and is recommended for healthcare workers, people who live or work in high-risk settings, and those who have had a positive PPD test in the past.
What is a 2-Step PPD Test?
A 2-step PPD test involves two PPD skin tests given one to four weeks apart. The first test is read 48-72 hours after it is given, and if it is negative, a second test is given. The second test is read 48-72 hours after it is given. If both tests are negative, it is unlikely that you have TB infection.
Why is a 2-Step PPD Test Recommended?
A 2-step PPD test is recommended for people who have never had a PPD test before or who have not had a PPD test in the past year. This is because some people may have a false-negative result on their first PPD test, meaning that they have TB infection but the test does not show it. A second test can help detect TB infection that may have been missed by the first test.
Should You Get a 2-Step PPD Test?
If you are a healthcare worker, work or live in a high-risk setting, or have had a positive PPD test in the past, you should get a 2-step PPD test. Even if you do not fall into these categories, you may still want to get tested if you think you may have been exposed to TB or if you have symptoms such as coughing, chest pain, or fever.
