If your Coumadin meter displays an “Error” message, first check the battery. Replace it with a fresh one. If the problem persists, ensure the test strip is correctly inserted and hasn’t expired. Refer to the device manual for detailed insertion instructions and expiration date location.
Incorrect Readings?
Inaccurate readings might stem from improper blood sample collection. Ensure you follow the manufacturer’s instructions precisely, including proper finger prick depth and adequate blood sample volume. Avoid squeezing the finger excessively; this can dilute the sample and yield inaccurate results. If the issue continues, try a different test strip from the same batch.
Calibration Problems?
Calibration issues are rare. If your meter consistently produces readings significantly different from your lab results, contact your physician or the manufacturer’s customer support for assistance. They may recommend recalibration or meter replacement. Keep records of your meter readings and lab results for troubleshooting.
Meter Not Powering On?
Beyond battery issues, a malfunctioning power switch can cause the device to fail to turn on. Examine the power switch for any visible damage or obstruction. If there’s damage, consider contacting the manufacturer for repair or replacement. Avoid using excessive force on any of the device’s components.
