Serum biomarker panel testing is proposed to inform the differential diagnosis of connective tissue diseases (CTDs) that share similar symptoms. Biomarkers are "chemicals" or proteins found in blood, urine or tissue that can indicate both normal and abnormal processes. Systemic lupus erythematosus (SLE) and other connective tissue diseases (e.g., rheumatoid arthritis, Graves disease, Hashimoto disease, Sjögren syndrome, antiphospholipid syndrome, polymyositis and dermatomyositis) can be difficult to diagnose because individuals often present with diverse, nonspecific symptoms that overlap. Currently, differential diagnosis depends on a combination of clinical signs and symptoms and individual laboratory tests. Recently, laboratory-developed, diagnostic panel tests with proprietary algorithms and/or index scores for the diagnosis of SLE and other CTDs have become commercially available.
There is one multi-biomarker test available proposed to aid in the diagnosis of SLE and other connective tissue diseases. This panel, Avise CTD (Exagen Diagnostics), contains 22 different tests. It combines two smaller panels, a 10-marker panel that incudes common SLE tests, as well as cell-bound complement activation products (known as Avise Lupus) and a 12-marker panel that focuses on CTDs other than SLE (known as Avise CTD). Avise CTD includes nuclear antigen antibodies markers to help distinguish CTD, a rheumatoid arthritis panel to rule-in or rule-out RA, an antiphospholipid syndrome panel to assess risk for thrombosis and cardiovascular events, and a thyroid panel to help rule-in or rule-out Graves disease and Hashimoto disease.

Serum biomarker panel testing with proprietary algorithms and/or index scores for the diagnosis of systemic lupus erythematosus and other connective tissue diseases is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
No controlled studies were found in the published literature that validates the clinical utility of assessing multiple biomarkers simultaneously.
