1. If the patient exhibits the following symptoms, it may be the case that no correct values can be ob-
tained:
• Acute dehydration
• Acute hypotension (low blood pressure)
• Shock
• Hyperosmolar hypoglycaemic condition (with or without ketosis)
2. Lipaemic samples: Cholesterol levels up to 500 mg/dL (13 mmol/L) and triglycerid levels up to
1,000 mg/dL (11.4 mmol/L) do not influence the results. Severely lipaemic blood samples were
not tested with the Beurer
GL48/GL49
blood glucose measuring system; therefore, using the
device with these samples is not recommended.
3. In the case of severely ill patients, blood glucose monitors for home use should not be used.
4. The effect of interfering substances on the measurements depends on the concentration in the
blood. The maximum concentrations of certain substances listed below do not significantly influ-
ence the measurements.
