Abstract
Skin tests are utilized in the follow up of leprosy patients, constituting one of the parameters for the classification of the clinical forms of this disease, its prognosis and even for treatment indication and follow up. These tests have been developed in the first quarter of this century and are based on bacilli suspensions obtained from human lesions or from infected armadillos. In this paper, we review the characteristics of lepromin or Mitsuda antigen and other alternative tests. The potential of recombinant antigens in the preparation of skin tests is also highlighted as a future perspective for the preparation of improved, standardized and more specific reagents, in comparison from those tests obtained from human lesions or armadillos.
