Fresh venous, capillary,arterial, or neonatal blood may be used. Caution should be taken to clear arterial lines beforeblood is drawn. Caution should be exercised in the interpretation of neonate blood glucose valuesbelow 2.8 mmol/L. Blood glucose determination with venous or arterial blood must be performedwithin 30 minutes of sample collection. Avoid air bubbles with the use of pipettes. Fresh venousblood specimens containing the anticoagulants EDTA or heparin are acceptable. Iodoacetate orfluoride/oxalate are not recommended.Decisions about whether to recommend alternative site testing (AST) should take into account themotivation and knowledge level of the patient and his or her ability to understand theconsiderations relative to diabetes and AST. If you are considering recommending AST for yourpatients, you need to understand that there is a potential for a significant difference betweenfingertip/palm and alternative site blood glucose test results. The difference in capillary bedconcentration and blood perfusion throughout the body can lead to sample site-to-site differencesin glucose results. These physiological effects vary between individuals and can vary within asingle individual based upon his or her behavior and relative physical condition. Our studies71
