– Capillary (finger) test
– After completion of meal
– Check BG 1 Hr PP
– (or) every 15, 20 or 30 min until 2 consecutive BG drops occur
– No addl. Food/insulin until test is completed

Measurement of After-Meal PeaksMeasurement of After-Meal Peaks
• Glucowatch Glucowatch (Cygnus/Animas)(Cygnus/Animas)– Takes readings every 10
minutes, following 2-hr warmup
– Can download to computer or retrieve readings manually
– May “skip” readings during periods of rapid rise or fall

• CGMS (Medtronic)CGMS (Medtronic)– Worn for 72 hrs (or
more), then data is downloaded
– Meals should be entered as “events” while wearing
– Calculates 3-hr post-meal averages
