Leprosy skin test
People who don't have leprosy will have little or no skin reaction to the antigen. Patients with a particular type of leprosy called lepromatous leprosy will also have no skin reaction to the antigen.
A positive skin reaction may be seen in patients with tuberculoid and borderline tuberculoid leprosy. Patients with lepromatous leprosy will not have a positive skin reaction.
