Comparison of Hb Sahli and Hb Electric Levels Using Autoanalyzer Devices in Clinics

Abstract

The aim of this research was to compare hemoglobin concentration measurements obtained using Sahli’s method, the electrical method, and an Autoanalyzer. An analytical comparative design with a cross-sectional approach was applied. The results showed that the average hemoglobin concentration measured by Sahli’s method was 12.87 g/dl, by the electrical method 12.68 g/dl, and by the Autoanalyzer 12.67 g/dl. The One-Way ANOVA test produced a p-value of 0.935 (> 0.05), indicating no significant difference among the three measurement methods. However, the electrical method showed the closest estimation to the Autoanalyzer results. Based on these findings, it is recommended that hemoglobin testing be performed immediately after the sample is obtained, ensuring results that accurately reflect the patient’s condition and minimizing the risk of false high or low values
