Some clinics, especially in urban areas, offer free TB skin testing, but may require patients to make appointments prior to arriving, since testing is not always offered all day. The NYU Langone Medical center's website lists local clinics in New York that provide free TB tests.
Most national pharmacy chains give patients the ability to book appointments online, including CVS, Walgreens and Walmart. These tests, although not free, are inexpensive, often starting at around $28, as of 2015. Some pharmacies discount the fees even further if a patient meets the criteria in order to qualify for free or reduced cost testing.
