Test Directory - Glucose (POCT)

POCT Equipment

Abbott Xceed Pro Meter.

Clinical Indications

Production of rapid blood glucose results may be used to determine the presence of hypo- or hyper-glycaemia, and to monitor blood glucose levels in diabetic patients.

Please note that diagnosis of Diabetes Mellitus must not be made on the basis of a glucose result obtained from any blood glucose meter. All such interpretation must only be made on the basis of laboratory results.

Sample Type

Capillary whole blood (e.g. finger-prick) or heparinised venous/arterial whole blood.

Sample Container

None required for finger-prick samples.

Sample Volume

0.6 uL

Sample Handling

Samples must be analysed immediately.

Special Precautions

The patient's finger must be washed before finger-pricking to avoid contamination from glucose in food.

Turnaround Time

A result is produced within 20 seconds.

Reference Range

Fasting 2.5 6.0 mmol/L
Random 2.5
7.8 mmol/L

Limitations

Serum or plasma samples cannot be used.

For glucoses <16.7 mmol/L the acceptable haematocrit range is 20 70%
For glucoses >16.7 mmol/L the acceptable haematocrit range is 20
60% 

Paediatric results <3.8 mmol/L need to be checked using a different method (e.g. on a blood gas analyser or by the laboratory).

Use of alcohol wipes interferes with the analysis.

Finger-prick samples are not suitable for use in severe dehydration/ peripheral shutdown.

Results falling outside of the range 3.0 20.0mmol/L should ideally be checked with a laboratory measurement using a venous sample.

Time Limit for Additional Tests

Finger-prick samples can only be used once.

If the test result is questionable or if clinical signs and symptoms appear inconsistent with the test result, re-test with a fresh sample or confirm the result by sending a sample to the laboratory.

Training

The test should only be carried out by a trained member of staff. If you have not been trained please see your ward based link nurse or contact the POCT team (x 8382) for training.
