Glucose
Order Code: GLU
Epic Lab Code: LAB82
Order Form: A-1a General Lab or Epic Req
Chemistry
6240 RCP
356-3527
Specimen:
Plasma
Collection Medium:
Plasma Separator Tube
Alternate Collection Media:
Call laboratory for additional acceptable specimen collection containers.
Minimum:
3 mL in light green top tube or 1 microtainer
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Analytic Time:
1 hour (upon receipt in laboratory)
Reference Range:
65-99 mg/dL Critical value (1 month-adults): <50 mg/dL and >450 The Expert Committee on the Diagnosis and Classification of Diabetes has defined impaired fasting glucose as greater than or equal to 100 mg/dL but less than 126 mg/dL. (Diabetes Care 28 (Suppl 1) S41, 2005) Pediatric Reference Ranges: Age Range Units 0-1 month 40-99 mg/dL 1 month-adult 65-99 mg/dL Critical value (0-1 month): <40 mg/dL and >300
Comments:
Falsely low values may occur in specimens which are not separated promptly from RBC's.
Test Limitations:
Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL). Hemolysis: No significant interference up to an H index of 1000 (approximate hemoglobin concentration 1000 mg/dL). Lipemia (Intralipid): No significant interference up to an L index of 1000 (approximate triglycerides concentration 2000 mg/dL). There is poor correlation between turbidity and triglycerides concentration.
Methodology:
Hexokinase/UV test
CPT Code:
82947
