Electochemical principle of Biamperometry
Heparinzed whole blood can also be sent to lab if capillary puncture is not possible ( ex: burned extremities or patient has a line to avoid repeated punctures). Glucose by meter levels that are >450 mg/dL ( > 300 mg/dL for NICU patients) will be confirmed via a whole blood specimen analyzed on the EML.
Reference range: 60-110 mg/dL; 30-90 mg/dL (Neonate)
