Secaucus, NJ, Nov. 01, 2017 (GLOBE NEWSWIRE) -- Quest Diagnostics (NYSE: DGX), the world’s leading provider of diagnostic information services, announced today that it will present results of five studies at the 2017 American College of Rheumatology (ACR) Annual Meeting, November 3 – 8, 2017 in San Diego.
The studies evaluate a broad range of laboratory technologies and best practices for aiding the diagnosis of several autoimmune disorders. These include testing for 14-3-3η (eta), a novel protein marker for rheumatoid and potentially other forms of arthritis. Quest Diagnostics was the first provider to offer 14-3-3η testing in the United States, which it now offers individually and as part of the IdentRA® panel.
"Rheumatic conditions affect nearly 46 million Americans, but they can be very complicated to diagnose,” said Stanley J. Naides, MD., FACP, FACR, Medical Director, Immunology, Quest Diagnostics, and lead author or co-author of all five studies. “Laboratory testing is increasingly essential to the management of autoimmune disease, as reliable and efficient diagnosis can often lead to interventions early in disease progression when the potential for a favorable outcome is greatest. At the American College of Rheumatology meeting, we look forward to shedding new light on the best diagnostic approaches for evaluating a broad range of these disorders.”
In recent years, the company has introduced several other services that aid the diagnosis of autoimmune disorders, such as inflammatory bowel disease, myositis, systemic sclerosis, PD-L1 monocyte expression for predicting disease activity in patients with systemic lupus erythematosus, and a new genetic marker, HLA-B*58:01, for evaluating risk of severe cutaneous adverse skin reactions (SCARs) to allopurinol. Later this quarter, the company expects to introduce a new service that performs IdentRA testing in combination with the Antinuclear Antibodies (ANA) by Indirect Immunofluorescence Assay (IFA) Cascade (also known as multi-tiered reflex testing), for a comprehensive approach to aiding differential diagnosis of the eight most common rheumatic diseases with one blood draw.

Among the data being presented at this year's annual meeting are:
Sunday, November 5, 9:00 – 11:00 A.M. (Poster Session)
A study performed to survey laboratory practices in ANA testing and a study to determine laboratory practices in interpreting and reporting ANA IFA pattern and compare them against guidelines. ANA testing is used to detect autoantibodies that attack components of a cells' nucleus and cytoplasm, and aids in determining if a patient has autoantibodies that may suggest an autoimmune disorder, such as systemic lupus erythematosus (often simply called lupus), Sjögren syndrome, and systemic sclerosis.
Tuesday, November 7, 9:00 – 11:00 A.M. (Poster Session)
Two studies evaluating the presence of 14-3-3η (eta) in patients with juvenile idiopathic arthritis. 14-3-3η has diagnostic potential in inflammatory arthritis and rheumatoid arthritis
Tuesday, November 7, 4:30 – 6:00 P.M. (Oral Session)
A study to determine whether apoptotic bodies (ApoBods) containing virally modified dsDNA from Parvovirus could induce autoimmunity in an animal model. Anti-dsDNA testing may be used to evaluate an individual for signs of lupus, and some research suggests a connection between the disorder and human parvovirus B19.
