Evaluation of A Digital Hemoglobin Analyser In Comparison With Hematology Cell Counter

Abstract

Background: Haemoglobin estimation is an important screening test for blood donor. Despite
many methods available, each method has some advantages and disadvantages. Hemoglobin estimation by
digital hemoglobinometre proved to be a very reliable, sophisticated, appropriate and ideal especially for a
blood donation setup and also reliable in comparison to hematology analyser. Materials and Methods: A
study of 250 Single donor platelet donors to evaluate a digital haemoglobin analyser- Dolphin was done in a
tertiary cancer care centre from August 2019 to October 2019.and data were compared to sysmec KX 21
cell counter which is one of the most accurate method for haemoglobin testing. Results: Out of 250 donors
247 were male and 3 were female. Mean value of Dolhin (mean 14.8 g/dl ) was higher by 0.6 compared to
reference (mean 14.2 g/dl) but not statistically significant (P > 0.05). In comparison to cell counter Dolphin
proved to be the cost effective with sensitivity and specificity more than 93%.. R square value is 0.9897
which indicates high precision. Conclusion: Digital hemoglobinometre – Dolphin gives comparable results to
cell counter and hence proved to be reliable and cost effective. [Kusimgar R Natl J Integr Res Med, 2019;
