AVISE CTD
The Advanced Rheumatology Test for The Differential Diagnosis of SLE
AVISE CTD is an advanced autoimmune rheumatic disease test specifically designed to aid physicians in the differential diagnosis of systemic lupus erythematosus (SLE). AVISE CTD is the only diagnostic test powered by patented Cell-Bound Complement Activation Products (CB-CAPs), stable biomarkers of complement activation, to help physicians better assess patients with suspected SLE.
What assays are included in AVISE CTD:
AVISE CTD contains the patented Lupus (SLE) biomarkers, CB-CAPs, which help to offer a 22% greater sensitivity compared to C3/C4, and 48% greater sensitivity compared to anti-dsDNA
Clinical Utility: AVISE CTD Test Report
There are many clinical scenarios that can benefit from the AVISE CTD test including:
- 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
State-of-the-art Methods:
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.
AVISE CTD is composed of an advanced two-tier lupus test assessment to help provide physicians the information needed to make a confident lupus diagnosis.
