Lyme IGXSpot

What this laboratory test evaluates

The IGXSpot test is an enzyme–linked immunospot assay that detects human T cells reactive to Borrelia/pathogen-specific antigens in vitro. It is recommended for the detection of very early and/or late Borrelia/pathogen infection and in seronegative patients’ whole blood samples. When combined with Lyme ImmunoBlot tests, this test provides information on the full spectrum of a patient’s immune response to infection and stage of disease.

How Sunridge uses laboratory information

Sunridge considers the medical question, symptoms, history, medications, prior results, and whether the finding could change care before recommending testing. A laboratory result is not interpreted in isolation and does not establish a diagnosis by itself.

Before requesting this test
