Neutrophil-Associated Antibodies
Also known as: ANTI-NEU
Use
Support the diagnosis of immune neutropenia in various autoimmune disorders including Felty syndrome, SLE, and drug-induced neutropenia. May also help diagnose febrile transfusion reactions and isoimmune neonatal neutropenia caused by antibodies to neutrophil-specific antigens or HLA antigens.
Special Instructions
Not provided.
Limitations
A positive result is not definitive for specific anti-neutrophil antibodies since anti-HLA antibodies and immune complexes may also cause a positive result. Test results should be correlated to clinical history and other data for accurate diagnosis.
