Collaboration Aims to Expand Access to Early Detection of Potential Disease Marker

Lucent Diagnostics, a brand of Quanterix Corporation (NASDAQ:QTRX), today announced a partnership with Life Line Screening (LLS), a national organization focused on identifying asymptomatic risks for chronic conditions in community health settings. Through the partnership, Life Line Screening will offer Lucent's non-invasive blood based biomarker test nationally, with programs in Florida, California, and Texas already underway. This partnership supports the goals of both organizations to provide non-invasive, easily accessible testing in the general public.

According to the Alzheimer's Association, an estimated 7 million Americans are living with Alzheimer's disease today, with another 6-7 million experiencing symptoms of Mild Cognitive Impairment (MCI). These figures underscore the urgent public health need for scalable testing options that can facilitate earlier identification of the disease in its most treatable phase.

"Too many chronic conditions go undetected until they become life-altering events," said Jim Waters, Chief Operating Officer at LLS. "By partnering with Lucent Diagnostics, we're able to continue to expand our mission of uncovering asymptomatic risks earlier and more equitably. This partnership has the potential to impact numerous lives by supporting more informed treatment pathways, and it's something we're excited to bring to communities across the country."

Now available to their network, LLS can continue its mission by bringing cutting edge blood tests in an accessible and convenient way. Through their mobile delivery model, LLS will provide testing opportunities in local venues such as community centers, churches, and senior centers. The results of these tests can then be shared to help primary care physicians facilitate early intervention and proactive lifestyle management for adults.

"Scientific rigor shouldn't stop at the laboratory door. Through LLS, Lucent Diagnostics is bringing validated, high-quality science into community testing networks, helping ensure that everyone has access to information for use by their physician and not only in a research setting. This is a critical step toward earlier, more reliable detection of Alzheimer's Disease," says Zachary Fernandes, Quanterix General Manager for Lucent Diagnostics.

Life Line Screening is a national provider operating in the 48 contiguous states. By hosting over 15,000 community events annually, they provide a scalable infrastructure that reaches individuals in both major metropolitan areas and underserved rural regions.
