Glucose, Whole Blood
EPIC: LAB5345, SOFT: GLUW
- Glucose, Whole Blood should ONLY be collected at the Royal Oak or Troy Hospital Campuses. Specimens should not be collected at any other Beaumont Laboratory drawsite, nursing home, or Outreach office.
- This test can be performed as either a fasting or random blood sugar.
Specimen Collection Criteria
Collect: One Dark Green-top Lithium Heparin tube. (Minimum Whole Blood: 1.0 mL)
Transport specimen STAT to the Laboratory after collection.
Specimen in which significant delays occur before arrival in the Laboratory (greater than 2 hours).
Inpatient Specimen Preparation
Transport the specimen STAT to the STAT Laboratory (Royal Oak) or Chemistry Laboratory (Troy).
Immediately analyze the whole blood specimen upon receipt in the Laboratory.
Specimen Stability for Testing:
Room Temperature (20-26°C or 68-78.8°F): 2 hours
Refrigerated (2-8°C or 36-46°F): Unacceptable
Frozen (-20°C/-4°F or below): Unacceptable
Specimen Storage in Department Prior to Disposal:
Specimens are disposed within 8 hours of testing.
Farmington Hills Chemistry Laboratory
Royal Oak STAT Laboratory
Troy Chemistry Laboratory
Sunday – Saturday, 24 hours a day.
Results available within 30 minutes of receipt in the Laboratory.
Fasting: 60-99 mg/dL.
Random: 60-139 mg/dL.
See Glucose assay.
- This assay is appropriate when rapid turn around time is important for patient management.
- If serum or heparinized plasma is left in contact with blood cells for extended periods, glucose will be metabolized. Glucose levels decrease by about 5-7 mg/dl per hour at room temperature in normal specimens containing normal numbers of RBC's and WBC's.
