6. Hematocrit: Test strip results are not significantly affected by
hematocrits in range of 30% to 55%. Hematocrit levels less than
30% may cause incorrect high readings and hematocrit levels
greater than 55% may cause incorrect low readings. If you do
not know your hematocrit level, consult your healthcare profes-
sional.
7. Patients undergoing oxygen therapy may have inaccurate results.
8. Altitude up to 3050 meters above sea level has no effect on read-
ings.
9. 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.
10. Increased cholesterol and triglyceride levels may interfere with
the way light is reflected producing erroneous meter results.
