Lifescan OneTouch Profile blood glucose monitor - Manual (Page 6)

PRECAUTIONS AND LIMITATIONS
• If you experience symptoms that are not consistent with your blood glucose results,
and you have carefully followed the procedure described in your owner’s booklet,
contact your healthcare professional immediately.
• DO NOT make significant changes to your medication program or ignore physical
symptoms without consulting your healthcare professional.
• If the message HI DANGER appears on the meter display, this indicates severe high
blood sugar (hyperglycemia); contact your doctor immediately.
• Note that extremes in whole blood hematocrits, above 60% or below 25%, can cause
false low results.
• Reducing substances, such as Vitamin C (ascorbic acid), have little effect on blood
glucose results when found in normal blood concentrations. However, abnormally
high concentrations of reducing substances in blood will cause false low test results.
• DO NOT use blood samples with preservatives that contain fluoride (in gray top test
tubes). You will get false low results.
• When testing, removal of the test strip prior to display of the blood glucose result
may give you a false result.
