Lepromin skin test

Alternative names:

leprosy test

How the test is performed:

The test is usually done at the health care provider's office. The extract sample is injected just under the skin, usually on the forearm, so that a small lump pushes the skin up. The lump indicates that the antigen has been injected at the correct depth. The site is labeled, usually with an ink pen.

How to prepare for the test:

People with dermatitis or other skin irritations may have the test performed at different locations on the body.

If your child is to have this test performed, it may be helpful to explain how the test will feel, and even practice or demonstrate on a doll. The more familiar your child is with what will happen and why, the less anxiety he or she will feel.

How the test will feel:

When the antigen is injected, there is a slight stinging sensation where the needle is inserted. After the reaction begins, the area will probably itch or burn.

Why the test is performed:

Leprosy is a chronic and, if left untreated, potentially fatal infection by the bacterial Mycobacterium leprae. This test is a tool for your health care provider to clinically diagnose this disease.
