Sonora Quest Laboratories Partners with Exagen to Provide Solutions to Arizona Rheumatologists and their Patients

PHOENIX (October 13, 2020)Sonora Quest Laboratories, the market share leader in diagnostic laboratory testing in Arizona, has announced an exclusive partnership with Exagen Inc. (Nasdaq: XGN), an organization dedicated to transforming the care continuum for patients suffering from debilitating and chronic autoimmune diseases. The partnership will expand access to Exagen’s AVISE portfolio of innovative products to rheumatologists and their patients in Arizona.

AVISE guides providers and rheumatologists in the optimization of the patient care journey through the differential diagnosis, prognosis and management of complex autoimmune diseases. 

“There is an overlap in health care disparities between the patient population at risk for Rheumatoid Arthritis, other autoimmune diseases, and COVID-19,” said Christina Noble, Chief Growth Officer, Sonora Quest Laboratories. “Offering access to Exagen’s AVISE portfolio on an in-network basis provides patients with expanded access to facilities and services, and enables rheumatologists to improve patient care with an earlier, more accurate diagnosis. With COVID-19 still a serious concern, this offering could not be timelier.”

Experts believe that the more underlying health conditions a person has, the higher their chance of having serious complications from COVID-19. In an effort to reduce the number of visits to the doctor’s office many physicians are requesting Exagen testing ahead of the consultation to more quickly identify the underlying autoimmune conditions and implement a patient management plan to address and monitor the patient’s progress for improved outcomes. 

More than 80 diseases occur as a result of the immune system attacking the body’s own organs, tissues, and cells. Some of the more common autoimmune diseases include type 1 diabetes, rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease. The AVISE portfolio offers a unique opportunity to positively impact the health disparities for at risk patients of autoimmune diseases.

“Exagen is excited to partner with Sonora Quest to offer this advanced testing solution to its provider and patient networks,” said Exagen President and CEO Ron Rocca. “The AVISE suite of tests is one of the most innovative on the market and our goal is to positively impact patient outcomes and ultimately save more lives.”
