Annex 1 : Information for Healthcare Professionals
Decisions about whether to recommend alternative 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 signicant dierence between ngertip and alternative
site blood glucose test results. The dierence in capillary
bed concentration and blood perfusion throughout the
body can lead to sample site-to-site dierences in glucose
results. These physiological eects vary between individuals
and can vary within a single individual based upon his or
her behavior and relative physical condition. Our studies
involving AST of adults with diabetes show that most
persons will nd their glucose level changes more quickly in
the ngers’ blood than the alternative 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 ngertip readings, he or she should
consider the delay or lag-time, aecting the reading
obtained from an alternative site.
