The Advanced Rheumatology Test for the Differential Diagnosis of SLE
AVISE CTD is an advanced autoimmune rheumatic disease test, powered by patented Cell-Bound Complement Activation Products (CB-CAPs), specifically designed to aid in the differential diagnosis of systemic lupus erythematosus (SLE).
THE BETTER COMPLEMENT TEST - Offering 22% greater sensitivity compared to low C3/C4.
The Advanced Rheumatology Test for the Differential Diagnosis of SLE.
There are many clinical scenarios that can benefit from the AVISE CTD test including:
- Patient Triage
- Assessment of ANA positive referrals
- Patients with clinical suspicion of a connective tissue disease but insufficient criteria for diagnosis
- Assessment of patients with overlapping symptoms
- Observation of Undifferentiated Connective Tissue Disease
- ANA positive fibromyalgia patients with clinical suspicion of underlying autoimmune inflammatory disease
AVISE CTD contains the patented SLE biomarkers, CB-CAPs, which help to offer a 22% greater sensitivity compared to C3/C4, and 48% greater sensitivity compared to anti-dsDNA.
Understanding how the AVISE Index Value is Calculated:
Accurate results depend on reliable test methods. That’s why AVISE CTD measures ANA by IFA using digital imaging as well as ELISA, and confirms positive ds-DNA results using immunofluorescence Crithidia assay.
All markers reported in AVISE CTD are carefully selected to provide maximum performance in the diagnosis of SLE and diseases that mimic lupus.
