The Hb values obtained by the hemocue hemoglobinometer were found to be higher than the actual Hb value by 1.5 g/dl. On the contrary, some studies [12] have demonstrated that Hemocue system is comparable to other standard laboratory techniques for hemoglobinometry and also that discrepancies of more than 1 g/dl between Hemocue and Coulter are uncommon.
Other investigators have found Hemocue – Hb values to be higher when compared to other standard methods [13].
