Collection Instructions

Draw fasting sample before giving the Glucose solution (Glucola). In addition to the specimen being sent to lab: If glucose meter is used in your area, follow your glucose meter procedure. Perform a fasting glucose on the glucose meter as a courtesy draw so procedure may be started.

1. If the glucose meter result is >140 mg/dL (greater than 140 mg/dL) DO NOT proceed with the tolerance. Send the blood sample to laboratory and have them run the
sample STAT. If the lab result is >140 mg/dL notify the ordering physician to determine if the tolerance test should be performed.
