Understanding Lab Tests for Leishmaniasis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Leishmaniasis is a parasitic disease caused by protozoan parasites of the genus Leishmania, transmitted through the bite of infected sandflies. This condition can affect the skin, mucous membranes, and internal organs, making accurate diagnosis essential for proper treatment.
Recommended Test
Leishmania Antibody (IgG)
This blood test measures IgG antibodies specific to Leishmania parasites. High levels of these antibodies indicate either an active infection or past exposure to Leishmania parasites. This test is essential for confirming the diagnosis of leishmaniasis and helps healthcare providers determine appropriate treatment strategies.

Diagnosing Leishmaniasis
Because leishmaniasis symptoms can vary widely and may resemble other conditions, laboratory testing is crucial for confirming the presence of Leishmania parasites. Blood tests can detect antibodies produced by the immune system in response to the infection, providing valuable diagnostic information.
Understanding Test Results
The Leishmania antibody test detects the immune system's response to the parasites. Elevated IgG antibody levels suggest that the body has encountered Leishmania parasites, though additional clinical evaluation may be needed to distinguish between active and past infections and determine the most appropriate treatment approach.
Important Considerations
