Junction Collaborates with GRAIL to Power Scalable Access to Galleri Multi-Cancer Early Detection Test

Digital health and clinical platforms can now operationalise Galleri seamlessly through Junction's ordering and diagnostic infrastructure.

Junction, the infrastructure platform for diagnostic testing and health data workflows, announced a collaboration with GRAIL to support scalable access to the Galleri multi-cancer early detection test across digital health platforms and clinical organisations.

Through Junction's diagnostic infrastructure, healthcare organisations can now integrate Galleri into their workflows with a unified ordering experience, embedded physician network, and streamlined operational support for complex testing.

The Galleri test is a blood test designed to detect a signal shared by more than 50 types of cancer, many of which lack recommended screening options today.

"As demand for proactive and preventative care grows, platforms need reliable infrastructure to operationalise advanced diagnostics at scale," said Maitham Dib, Junction's Founder. "Our collaboration with GRAIL helps bring Galleri into real-world care models more efficiently."

Organisations can now:

Order the Galleri test directly through Junction

Support multi-state clinical operations

Manage workflows for complex testing

Streamline patient and provider experiences

Provide enhanced physician follow-up calls with patients

"Single-cancer screenings are an important tool for detection and diagnosis of five cancers in the U.S, but 70 per cent of cancer deaths are caused by cancers without recommended screening tests. GRAIL is excited to collaborate with Junction to broaden access to the Galleri multi-cancer early detection test through a streamlined experience for healthcare organisations and prescribing providers," said Megan Hall, PhD, vice president of Medical Affairs at GRAIL. "Junction's infrastructure helps simplify the operational steps around offering Galleri, making it easier for providers to integrate the test into care delivery."

Junction provides the infrastructure that powers modern healthcare platforms. Through a single API, Junction enables digital health companies, healthcare providers, and technology platforms to integrate lab testing, wearable device data, and diagnostics directly into their products.

Junction's platform manages the operational complexity behind healthcare data — from ordering tests and coordinating specimen collection to receiving standardised results and streaming continuous device data — so teams can build patient experiences that are embedded, reliable, and scalable.
