This is nonsense and impracticable. If you look at any EQA scheme you will see at least a 1 mmol/L error between labs not to mention time sampling errors. Clinically it makes little or no sense. The rate of change of glucose does not require instant immersion in ice slurry and analysis within 30 minutes

If that cannot be achieved, a tube containing a rapidly effective glycolysis inhibitor, such as citrate buffer, should be used for collecting the sample. Tubes with only enolase inhibitors, such as sodium fluoride, should not be relied on to prevent glycolysis.
