AARFID - Mississippi Blood Bank Services (MBS) (via RFID Journal)
"Managing the inventory of blood products—MBS supplies blood to 50 hospitals and medical facilities throughout Mississippi—is a complex logistical process. For years, MBS has used bar codes and scanners to help automate processes and improve record
keeping. Yet, in an era of growing cost pressures and increased demand for blood, the 25-year-old organization has recognized that radio frequency identification can help it save dollars and lives..."
"...AARFID, a firm located in Eden, N.Y., specializing in assembling company-specific RFID solutions and systems integration. After several weeks of discussions, research and brainstorming with Chad Carpenter, president of AARFID, Patel and Carpenter agreed on a pilot using 1,000 units of blood products. The goal was to locate specific blood
products from trays stored inside the cooler using RFID interrogators and passive tags attached to the blood bags..."
"...First, MBS had to find a way to eliminate interference caused by the metal
trays holding the blood bags, which rendered reading the passive tags nearly impossible. Other electronic devices, including telephones, also caused interference problems. Eventually, after testing a variety of passive tags—ranging from 13.56 MHz 915
MHz—it became clear that the high water content of the blood, combined with the metal trays, would cause additional problems. As a result, MBS swapped the metal trays for plastic ones, moved phone locations and replaced any packing materials using
metal with plastic. "In some cases," says Carpenter, "we devised low-tech solutions to high-tech problems."
