Fast, Secure, and Fully Automated Delivery of Laboratory Results at ZLZ

Central Laboratory Zurich (ZLZ) is a state‑of‑the‑art medical laboratory operating 24/7 and serving leading clinics, hospitals, and medical practices across the Zurich region. Known for its high diagnostic standards and ability to process large testing volumes, ZLZ plays a critical role in ensuring timely, accurate, and secure laboratory services for thousands of patients every day.

The Challenge

ZLZ needed a way to deliver sensitive laboratory results quickly, securely, and without manual intervention. The urgency intensified during the COVID‑19 pandemic, when turnaround time became mission‑critical for both patients and healthcare providers.

The existing processes could not provide the necessary speed, automation, or reliability under extreme testing volumes. To address this, the laboratory required a digital workflow capable of delivering results to the correct patient, operating reliably at scale, ensuring full anonymity and data protection, adapting quickly to evolving needs, and being implemented within an exceptionally short timeframe.

The Solution

To meet ZLZ’s urgent needs, Xpert implemented an automated results‑delivery workflow and brought it into productive use within just 12 days.

The system was designed to handle extreme testing volumes reliably, deliver each result to the correct recipient, and maintain strict data‑protection standards. A fully anonymized process ensures that no personal data is stored, while PDF reports are automatically removed after a defined retention period. The solution consistently supported high throughput during the pandemic and ensured secure, uninterrupted operations.

  • Send personalized SMS messages with secure access links.
  • Authenticate patients using anonymized unique identifiers.
  • Process several hundred laboratory results per hour reliably.
  • Transmit all laboratory data in fully anonymized form.
  • Delete PDF reports automatically after 96 hours.
  • Operate securely without storing personal information.
