Understanding Lab Tests for Leishmaniasis Recidivans
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Leishmaniasis recidivans is a rare, chronic form of cutaneous leishmaniasis caused by Leishmania parasites. This condition is characterized by recurring skin lesions that appear at the site of a previously healed infection, making accurate diagnosis essential for proper treatment.
Recommended Test
Leishmania Antibody (IgG)
This test measures IgG antibodies against Leishmania parasites in the blood. Elevated levels of these antibodies can indicate leishmaniasis recidivans, a chronic and recurrent form of cutaneous leishmaniasis where lesions repeatedly appear at the site of a previously healed infection. The presence of specific IgG antibodies helps confirm the diagnosis of this rare condition.

Diagnosing Leishmaniasis Recidivans
Due to its recurrent nature and similarity to other skin conditions, leishmaniasis recidivans requires specific laboratory testing to confirm the presence of Leishmania parasites or the body's immune response to them. Blood tests that detect antibodies can provide valuable diagnostic information.
Understanding the Test Results
The Leishmania antibody test detects the immune system's response to the parasite. Positive results, particularly elevated IgG levels, suggest current or past infection with Leishmania parasites. In the context of recurring skin lesions, this can support the diagnosis of leishmaniasis recidivans.
