Troubleshooting
Unexpected Results
When results do not reflect the patient’s condition, repeat the test using a fresh cartridge
and sample. If results are still suspect, test the lot of cartridges in use with i-STAT control
solutions. If the controls are in range, there may be an interfering substance in the
sample. Check the Cartridge and Test Information sheets for the test in question. Test by
another method to verify the result. If the controls are out of range there may be a
problem with that particular cartridge lot. Use another lot number or repeat the test using
another method, and refer to Support Services Information in the Technical Bulletin
section of the i-STAT 1 System Manual.
Startup Messages
The handheld performs self-checks when it is turned on. If a condition that should be
corrected in the near future, but that will not affect results, is detected, a warning is
displayed. The operator presses the 1 key to access the Test Menu. The analyzer can be
customized to lock out the operator until the corrective action is taken.
