UPPSALA, SWEDEN, AND SALT LAKE CITY / ACCESS Newswire / February 3, 2026 / Sweden-based Rarity Bioscience today announced that ARUP Laboratories, a leading national reference laboratory and nonprofit enterprise of the University of Utah, has become the first commercial laboratory in the United States to validate and offer its groundbreaking superRCA^™ assay for research applications.

This milestone follows a year-long collaborative agreement between the two organizations, aimed at advancing high-sensitivity molecular diagnostics in clinical and research applications.

Developed by Rarity Bioscience, the superRCA^™ (Rolling Circle Amplification) assay delivers unparalleled sensitivity for mutation detection. The technology has significant implications for precision medicine, diagnostics, and clinical trials, enabling detection levels previously unattainable with conventional methods.

"Having a strong U.S. partner like ARUP is a major step forward for Rarity," said Linus Bosaeus, CEO of Rarity Bioscience. "Together, we can bring the benefits of superRCA to patients and researchers at scale, helping accelerate innovation in diagnostics and treatment monitoring."

ARUP Laboratories views the introduction of superRCA as a leap forward in diagnostic precision. "This is a very exciting technology," said Tracy George, MD, ARUP chief scientific officer and Innovation Business Unit president. "The sensitivity of superRCA opens new doors for earlier and more accurate detection of disease. The data is truly astonishing. We see this assay as a new tool for supporting precision medicine and improving outcomes in both clinical and trial settings."

The launch underscores both organizations' commitment to scientific innovation and improved patient care through advanced molecular solutions.
