If you’re concerned about normal TB, you may be wondering whether you should get a 2-step PPD test. At Nao Medical, we offer urgent care services in NYC, including skin testing for TB. Here’s what you need to know about the 2-step PPD test and whether it’s right for you.
What is a 2-Step PPD Test?
A 2-step PPD test is a type of skin test used to check for TB infection. It involves two separate tests, each administered at least a week apart. The first test is used to establish a baseline, while the second test is used to confirm the results of the first test.
Who Should Get a 2-Step PPD Test?
A 2-step PPD test is recommended for people who are at higher risk of TB infection, such as healthcare workers, people who live or work in close quarters with others, and people who have recently immigrated from countries with high rates of TB. It’s also recommended for people who have had a negative PPD test in the past but are now being retested.
How is a 2-Step PPD Test Administered?
A 2-step PPD test is administered by injecting a small amount of PPD (purified protein derivative) under the skin of the forearm. The injection site is then checked after 48-72 hours to see if there is a reaction. If there is no reaction, a second test is administered at least a week later.
What Happens if You Test Positive?
If you test positive for TB infection, further testing will be needed to determine whether you have latent TB infection or active TB disease. Treatment may be recommended to prevent the infection from progressing to active disease.
