Glucose, Fasting
Test Name Glucose, Fasting
Specimen Type / Requirements Container Type = Gold (SST) Minimum Testing Volume = 1ml Serum Tube must fill to at least ½ or greater of its vacuum capacity
Specimen Handling Collection Instructions: Serum or plasma (heparin), free from hemolysis, collected with or without gel separator. If fasting specimen is requested, patient must be fasting for at least 8 hours Write your initials, date and time of collection on the collection label. Stability: Stable at room temperature for 8 hours and 3 days refrigerated at 2-8°C. Transportation: Transport at room temperature ASAP. Laboratory Staff Instructions: Spin sample if collection time and time sample gets to the core lab exceeds 2hrs. Separate serum after clotting or plasma from cells immediately to reduce loss of glucose through in vitro glycolysis. Sample Rejection Criteria: Grossly hemolyzed samples, Unlabeled or Not Sufficient Quantity Samples will be rejected
