The HemoCue measures hemoglobin concentration by using photometry and reading the sample at two different wavelengths. This allows for accurate measurements even in patients with high white blood cell counts, as the method is not affected by the presence of other colored substances in the sample. The reaction does produce a colored complex, but this alone would not be enough to ensure accurate measurements in patients with high white blood cell counts. The use of a cuvette is also not necessarily relevant to the accuracy of the measurement in these patients.
