Full blood count, haemoglobin, red blood cell count, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, nucleated red blood cells, white cell count, neutrophils, lymphocytes, monocytes, eosinophils, basophils, platelets.

Samples required

EDTA blood (purple cap/ black cap ring, 4 mL tube). Smaller tubes are available for paediatric samples.

Please send separate sample if requesting with Biochemistry EDTA tests (e.g. HbA1c)

Erroneous results can arise from aged samples (elevated mean cell volume), and contaminated samples (from drip lines).

Test indications

General first line screen depending on clinical presentation, covering a wide range of conditions including pre- and post-operatively, and investigation of anaemia.
