Comments

This is a non-fasting test. 1. Give patient 75g glucose drink to be consumed in 5 mins. 2. Patient must not eat, drink or smoke during the test duration (water is permitted). 3. Collect sample at 1 hr post consumption of drink. If the patient vomits within the 1 hour challenge period or is 15 minutes late for testing, the test is cancelled and no specimen is collected. The patient is to be re-booked for another day. NOTE: No other glucose drink substitution is acceptable e.g. soft drink. LAB NOTES: If no fluoride oxalate is received, but there is a serum-gel tube coinciding with the GCT collection time, providing this sample is within appropriate stability time (i.e. must be spun within 3 hrs of collection): Mark the sample as urgent, label with '+GLU', spin and hand deliver to the Core Biochemistry scientist. If the 1hr sample is not received because the test has been cancelled, register request as SPECB.
