Out of Range message
The result is above (up arrows) or below (down arrows)
the limits of the system’s measurement range, as described
in Appendix E, Performance Characteristics.
1. Check the source and result, and ascertain whether a
value outside the range is likely.
2. Check for sample movement during measurement.
3. Check the fluid in the sample path for bubbles.
4. Perform a wash.
5. Ensure that you use the correct sample collection
techniques and anticoagulant, as described in Sample
Collection Devices and Anticoagulants in Section 1.
6. Ensure that you use the recommended storage,
handling, and mixing techniques.
7. Retest the sample.

glucose or lactate result on
reports The system detects substances in the sample that may
interfere with glucose or lactate measurement.
1. Check the sample source and determine whether the
presence of an interfering substance is likely. See
Appendix E, Performance Characteristics, for a list of
interfering substances.
2. If the message appears on multiple patient samples
that do not contain interfering substances, replace the
appropriate biosensor, as described in Replacing the
Glucose and Lactate Biosensors in Section 3.
