Hemoglobin analysis was performed at the station. The hemoglobin concentration was measured by taking one finger-prick blood sample from each pregnant woman using a HemoCue Hb 301. A prick was made on the tip of the middle finger after the site was cleaned with a disinfectant. The first drop of blood was cleaned, and the second drop was collected to fill the microcuvette which is then placed in the tank holder of the hemoglobin concentration measuring device. The performance of the meter was verified daily using a control standard to increase the reliability of the test. First, the microcuvette holder was pulled to its loading position and when the reader was ready to use capillary blood, the sample to be examined was filled in one continuous process. Within 10 min of filling, it was placed in the holder and pushed into its measuring position. Finally, after 15 to 60 sec, the result was displayed and recorded using WHO field survey recommendation techniques (9 (link)).
