Yersinia enterocolitica Antibody, IgA by Immunoblot
Also known as: YER IGA
Use
Immunoblot can be used as an adjunct tool in the diagnosis of Yersinia enterocolitica infection. The presence of IgA and IgG antibodies to Y. enterocolitica Yop proteins can also aid in the diagnosis of post-infectious autoimmune disorders associated with Y. enterocolitica (e.g., reactive arthritis, erythema nodosum, Graves Disease, and Hashimoto thyroiditis).
Special Instructions
This test is performed using a qualitative immunoblot technique and is considered a laboratory-developed test (LDT). It is run in a CLIA certified laboratory and is intended for clinical purposes. Cross-reactivity with Borrelia burgdorferi, which can cause an arthritis indistinguishable from arthritis due to Y. enterocolitica, has been demonstrated.
Limitations
This test has not been cleared or approved by the US Food and Drug Administration. Results should be interpreted in the context of other clinical findings and laboratory data. Reactive results may occur due to cross-reactivity, so they should be considered in correlation with clinical findings.
