Abstract
Abstract: This article aimed to analyze the prevalence of heterozygous carriers of hemoglobin S in blood donors at the Amapá State Institute of Hematology and Hemotherapy (HEMOAP). The variables ethnicity, gender in the periods of 2016 and 2017, made available by the Hemovida blood bank management system of the Ministry of Health, were analyzed. The results obtained through the analyzes in 2016 and 2017 were 1.75% and 1, respectively. 3%, the data revealed that the prevalence among these donor carriers is higher in males of mixed race. Additionally, patients with sickle cell trait are asymptomatic and are clinically and hematologically normal, being able to donate blood. It is concluded that the frequency of sickle cell trait in HEMOAP underlines the importance of carrying out research on sickle cell carriers in blood centers, with the purpose of improving the quality of transfused blood to the recipient and health guidelines for the donor.
