9. Patients undergoing oxygen therapy may have inaccurate results.
10. Altitude up to 3050 meters above sea level has no effect on
readings.
11. Test results may be false if the patient is severely dehydrated or
severely hypertensive, in shock, or in hypoglycemic-hyperosmo-
lar state (with or without ketosis). Critically ill patients should
not be tested with home-use blood glucose meter.
12. Elevated cholesterol and triglyceride levels may interfere with
the way light is reflected producing erroneous meter results.
13. Recent studies have shown that EMI can cause electronic medi-
cal device performance degradation and could lead to inappro-
priate therapy.
14. Grossly lipemic (fatty) samples may interfere with some meth-
odologies. To be aware of such interferences, patients under the
supervision of their physician should have baseline glucose val-
ues established by a clinical laboratory method prior to start-
ing home glucose monitoring. These baseline values should be
checked periodically thereafter.
