Special Instructions

In situations of decreased peripheral blood flow, fingerstick blood testing may not be appropriate, as it may not reflect the true physiological state. Examples would include, but are not limited to: severe dehydration caused by diabetic ketoacidosis or the hyperglycemic hyperosmolar nonketotic state, hypotension, shock, decompensated heart failure NYHA Class IV, or peripheral vascular disease. Clinical judgment is advised when interpreting ACCU-CHEK results on the critically ill patient. Patient’s hematocrit should be between 10% and 65%. As a matter of good clinical practice, caution is advised in the interpretation of neonate glucose values below 50 mg/dl. Galactose > 15 mg/dl can give falsely elevated test results. Glucose values in neonates demonstrating symptoms of galactosemia should be confirmed with a laboratory reference. Lipemic Samples with Triglycerides >1800 mg/dL may falsely elevate glucose results. Intravenous administration of ascorbic acid which results in blood concentrations of ascorbic acid >3 mg/dl will cause overestimation of blood glucose results
