Test Directory - Haemoglobin (POCT)

POCT Equipment

HemoCue 201+

Clinical Indications

Production of rapid haemoglobin results may be used to evaluate anaemia and polycythemia.

Sample Type

Capillary whole blood (e.g. finger-prick).

Venous or arterial samples taken into EDTA, heparin or fluoride tubes.

Sample Container

None required for finger-prick samples.

Sample Volume

10 uL

Sample Handling

Samples must be analysed immediately.

Special Precautions

Bubbles in the measuring cuvette must be avoided.

Turnaround Time

A result is produced within 15 60 seconds

Reference Range

Adult male 13.0 18.0 g/dL

Adult female 11.5 15.0 g/dL

Limitations

Blood with a high lipid content (e.g. patients on Total Parenteral Nutrition) will give falsely high readings, and must be sent to the laboratory for testing.

Blood with a very high white cell count (>60 x 10.9/L) may give falsely high readings, and must be sent to the laboratory for testing.

Clinical diagnosis must not be made on the basis of a haemoglobin result obtained from the HemoCue 201+. All such interpretation must only be made on the basis of laboratory results.

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.
