Healthcare Professionals: Follow the infection control procedures appropriate
for your facility.
WARNING: Patients receiving peritoneal dialysis using solutions containing Icodextrin
(e.g. Extraneal, Icodial) should not use the Accu-Chek Aviva Test Strip. It could cause an
overestimation of glucose results.
Decisions about whether to recommend alternate site testing (AST) should take into account
the motivation and knowledge level of the patient and his or her ability to understand the
considerations relative to diabetes and AST. If you are considering recommending AST for
your patients, you need to understand that there is a potential for a significant difference
between fingertip and alternate site blood glucose test results. The difference in capillary
bed concentration and blood perfusion throughout the body can lead to sample site-to-site
differences in glucose results. These physiological effects vary between individuals and can
vary within a single individual based upon his or her behaviour and relative physical condition.
Our studies involving AST of adults with diabetes show that most persons will find their glucose
level changes more quickly in the fingers’ blood than the alternate sites’ blood. * This is
especially important when glucose levels are falling or rising rapidly. If your patient is used to
making treatment decisions based upon fingertip readings, he or she should consider the delay,
or lag-time, affecting the reading obtained from an alternate site.
