NYC Tuberculosis Testing: A Guide to the 2-Step PPD Test

Read Time: 2 minutes

If you’re concerned about tuberculosis (TB), you may be wondering if you should get a blood test to help diagnose the disease. At Nao Medical, we offer the 2-Step PPD Test, a skin test that can help detect TB in its early stages. Here’s what you need to know about this test and how we can help.

What is the 2-Step PPD Test?

The 2-Step PPD Test is a skin test that helps detect tuberculosis. It involves injecting a small amount of purified protein derivative (PPD) under the skin of your forearm. After 48-72 hours, a healthcare provider will check the injection site for a reaction. If there is a reaction, it means you have been exposed to TB bacteria at some point in your life.

Why is the 2-Step PPD Test important?

The 2-Step PPD Test is important because it can help detect TB in its early stages. Early detection is crucial for effective treatment and preventing the spread of the disease. If you have been exposed to TB bacteria, but do not have active TB disease, you may be a candidate for preventive treatment.
