Summary: | Background: Glycolysis is not completely or predictably inhibited by the
glucose preservative currently in use, with glucose values falling by as much as 0.5
mmol/L during a 2-4-h period after sample collection. Immediate centrifugation of all
samples is also impractical and therefore misdiagnosis of disease can occur,
especially if more emphasis is being placed on fasting glucose for the diagnosis of
diabetes.
Methods: Glycolysis at room temperature was evaluated over time using
glyceraldehyde alone as well as in conjunction with standard antiglycolytic
agents.
Results: Glyceraldehyde alone does not inhibit glycolysis completely.
The combination of 11mmol/L glyceraldehyde, 119 mmol/L sodium fluoride and 21.7
mmol/L potassium oxalate gave the best antiglycolytic results. The glucose values
measured in samples stored at room temperature for 48 h was no different from those
measured in samples centrifuged immediately after venepuncture and this is clinically
superior to conventionally used sodium fluoride and potassium oxalate.
Conclusion: Plasma glucose concentrations obtained from blood collected
into tubes containing glyceraldehyde, sodium fluoride and potassium oxalate will more
closely reflect those of the patient at venepuncture. |
