Babesia duncani (WA1) Antibody (IgG), IFA
Also known as: WA 1 IgG Antibody, IFA, WA-1 IgG Antibody, IFA, Babesia duncani IgG Antibody
Use
This immunofluorescence assay (IFA) detects IgG antibodies to Babesia duncani (WA1), a tick‑borne protozoan that causes babesiosis with symptoms similar to B. microti, primarily in the Pacific Northwest. It provides evidence of exposure or infection and aids in differential diagnosis of febrile and hemolytic illnesses following tick bites.
Special Instructions
Not provided.
Limitations
A single negative IgG IFA result does not rule out Babesia infection. Cross‑reactivity with other Babesia species may yield false positives. Results should be interpreted alongside clinical context and may require additional testing (e.g., PCR or FISH) when suspicion remains high.
