Yersinia enterocolitica Antibodies (IgG, IgA)
Clinical Use
Order TestUse
This test measures IgG and IgA class antibodies against Yersinia enterocolitica, which can aid in the diagnosis of infection or post-infectious complications. Results assist in identifying antibody presence, with IgG and IgA levels helping to distinguish between serologic responses and potential clinical manifestations such as reactive arthritis or other autoimmune sequelae.
