An evaluation of the HemoCue for correcting the haemoglobin value of lipaemic samples.
HemoCue, an instrument for measuring B-haemoglobin, is described as correcting for the turbidity caused by high white cell counts or hyperlipaemia. It was evaluated for its ability to correct haemoglobin measurement for hyperlipaemia against a previously published method and found to perform adequately, but with a small constant positive bias.

The erroneous haemoglobin-hyperlipidaemia relationship.
Hyperlipidaemia, whether primary or secondary to parenteral feeding with intravenous lipid emulsions, causes the haemoglobin level to be erroneously high when measured spectrophotometrically. Contrary to a previous report, evidence is presented which suggests a relationship between the amount of the false rise in the haemoglobin level and the type and degree of hyperlipidaemia.
