Hilgraeve, Inc. Announces DIANON Systems, Inc. Selects HyperSend for Secure Internet Delivery of Test Results
Service Delivers Secure Diagnostic Results to Physicians

Monroe, Mich., June 26, 2002 - Hilgraeve, Inc., a long-time leader in data communications software, announced today that DIANON Systems, Inc. (NASDAQ: DIAN) has selected the company’s HyperSend system as one of its tools for secure Internet delivery of medical diagnostic test results. DIANON Systems is a leading national provider of cancer and genomic diagnostic services. HyperSend will enable DIANON to “push” test information directly to physicians through the Internet – a secure and cost-effective alternative to faxes, teleprinters or physical delivery.

“DIANON recognized the growing demand for secure Internet delivery of diagnostic results,” said Steve Clayton, Sr. Vice President and CIO at DIANON. “We wanted a solution that would deliver test results to our clients’ offices securely and verifiably with the convenience and ease of use that email provides. After investigating several options, we selected HyperSend.”

Secure delivery of lab reports with HyperSend eliminates the cost, delay, and risk of faxing, teleprinting, and physical delivery, and is more convenient than portal solutions that require recipients to visit Web sites to pick up test results. Results are sent directly to referring physicians’ computers, and print out automatically without any effort on the part of recipients. Recipients get the convenience of both a hardcopy and electronic copy of test results. Medical labs enjoy reduced telecom, hardware, and courier expenses, plus peace of mind with a robust, HIPAA-ready system that verifies delivery to the correct party.

“The impending HIPAA regulations are very unsettling to many and for good reasons,” said Matt Gray, president and CEO of Hilgraeve. “Healthcare executives cannot be certain about the specific impact of the regulations on their organizations. Regardless of what the final regulations turn out to be, HyperSend provides medical labs with a flexible, easy-to-implement HIPAA-ready solution that lets them deliver test results through the Internet today, safely, securely and economically.”

HyperSend has been widely adopted in the healthcare industry as a secure method for exchanging patient-related information through the Internet. It uses highly regarded industry-standard encryption protocols that pass effortlessly through firewalls and ensure safe, reliable transfer of healthcare data of all kinds – lab reports, HL7 data, charting or claims information, even large medical images – among service providers, hospitals, medical practices, and healthcare business partners.

Designed for easy, economical deployment by healthcare organizations that serve dispersed communities of healthcare clients and/or professionals, HyperSend accomplishes secure data transfer without the expense of VPNs, WANs, or EDI. Its patent-pending client-server architecture can be installed across a whole community of users from a central location, without visiting each site; clients require only a computer and Internet connection.

HyperSend acts as a secure conduit for automated transfer of healthcare data regardless of format or size, and couples easily with legacy systems (LIS or POMIS), Web sites and portals. The system can be administered easily from a central location, and provides a complete audit trail of all data transfers.
