Background: In any blood bank, screening for anemia by hemoglobin level measurement is an essential step preceding blood donation. Aim: This study aimed to determine the accuracy of hemoglobin measurement by finger stick using the portable hemoglobin photometer (PHP) CompoLab TS (Fresenius Kabi GmbH). Methods: We recruited a total of 270 randomly selected blood donors in the blood bank of Princess Iman research and laboratory sciences Center at the Jordanian Royal Medical services between October 2018 and February 2019. Capillary samples were collected by finger sticking and hemoglobin concentrations were measured by CompoLab TS (Fresenius Kabi GmbH). Reference venous hemoglobin levels were measured using the automated Sysmex XN1000 analyzer. Results were analyzed using Microsoft Office Excel 2007. Results: Among the 270 subjects in this study, the mean (SD) of capillary PHP hemoglobin and venous Sysmex hemoglobin were 15.56 (1.79) and 15.10 (1.72) g/dL, respectively. Pearson's correlation coefficient (r = 0.93) suggests a strong positive correlation. The bias (limits of agreement) was 0.47 (-0.79, 1.72) g/dl and the accuracy in donor categorization was 96.7%. Conclusion: The PHP categorized blood donors to high accuracy and the correlation between its hemoglobin concentrations and those of the automated hematology analyzer was excellent with a small overestimation over reference . Therefore, we recommend the use of PHP as a suitable screening method for anemia at our blood bank. Abbreviations: PHP = portable hemoglobin photometer.
