Featured autoimmune tests from Quest
Below are some of our tests for autoimmune diseases. Every one meets the very highest standards for clinical validation and actionability:
- 14-3-3 eta Protein detects an inflammatory mediator, 14-3-3 eta, known to contribute to the pathophysiology of rheumatoid arthritis. This new biomarker indicates more severe disease in both early and established disease
- Rheumatoid Arthritis Diagnostic Panel IdentRA™ with 14-3-3 eta uses a novel biomarker to detect rheumatoid arthritis (RA), erosive psoriatic arthritis in patients who may have psoriasis, or juvenile idiopathic arthritis. It may also help differentiate from other inflammatory conditions such as osteoarthritis, osteoporosis, gout, lupus, Sjögren’s syndrome and systemic sclerosis
- Inflammatory Bowel Disease Differentiation Panel helps distinguish ulcerative colitis from Crohn’s disease in patients with inflammatory bowel disease
- ANCA Screen uses ANCA antibodies to help diagnose systemic vasculitis and inflammatory bowel disease (IBD). C-ANCA helps diagnose granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). P-ANCA helps diagnose MPA and EGPA. Atypical P-ANCA helps differentiate IBD.
- Crystals, Synovial Fluid helps identify synovial fluid crystals that, when present, aid in the diagnosis of gout and pseudogout
- HLA B*5801 can indicate possible risk for severe skin reactions to allopurinol, a common treatment for gout
- Calprotectin, Stool detects intestinal inflammation. While not diagnostic, the test can help distinguish IBD from non-inflammatory disorders and, in some IBD patients, assess disease activity and severity
- Lactoferrin Quantitative Immunoassay helps distinguish active inflammatory bowel disease (IBD) from non-inflammatory irritable bowel syndrome (IBS)
