Ehrlichia & Anaplasma Elispot

Overview

The Ehrlichia & Anaplasma EliSpot test assesses T-cell mediated immune responses to Ehrlichia and Anaplasma antigens using a venous blood sample. EliSpot technology evaluates cellular immune activity, which can be particularly relevant in individuals who do not mount a measurable antibody response.

Clinically, this test may be useful when exploring symptoms that follow tick exposure and are suggestive of tick-borne infection. Cellular immune testing can provide complementary information to antibody-based IgG or IgM testing by focusing on active T-cell responses.

Practitioners typically interpret results alongside symptom history, exposure risk, timing of illness and other laboratory findings. When reviewed in context, the test can support informed discussions with clients about immune responses related to Ehrlichia and Anaplasma exposure.
