My supervisor is seeking information about compatibility with either the Tango or the Echo and HCLL. Are they bidirectional? Are you interfaced with your LIS? Is there a software bug with the Echo that requires you to load only 4 specimens at a time and wait for them to process before adding more? Can you comment on the instruments reliability and down time issues? How timely is the service response? How long does it take to get STAT test results? How much tech time is spent attending to the instrument? Is it really walk-away? Does it save you about one tech during your day shift? We would appreciate the opportunity to talk with users as we make our decisions to purchase Blood Bank automation, so any help you could give us would be great. You can contact Audrey Faust, Central Laboratory Supervisor, 608-258-6903 or Barb Utphall, Blood Bank Technical Specialist, 608-258-6927. Thank you!
