Níveis de vitamina B12 e parâmetros do hemograma em indivíduos atendidos em um laboratório de análises clínicas da Serra Gaúcha

Abstract

Introduction: Vitamin B12, essential for the human body, is obtained mainly from foods such as meat, fish and dairy products. Its deficiency manifests subtly mild symptoms, but can generate serious health problems, such as: megaloblastic anemia, digestive changes and neurological changes, among others. Objective: The present study sought to evaluate vitamin B12 levels and blood count parameters in individuals treated in a clinical analysis laboratory in Serra Gaúcha, in the state of Rio Grande do Sul, Brazil. The intention is to analyze the predominant changes and verify whether the literature findings are repeated in this population. Method: An analytical, descriptive and retrospective study was carried out from July 2022 to July 2024 in a database, observing the following parameters: age, sex, medication, vitamin B12, hemoglobin, mean corpuscular volume (MCV). Results: The data found predominantly presented normal values in the majority of individuals studied by sex and age. The elderly were the patients who had the highest percentage of vitamin B12 deficiency (2.1%) and 12% had anemia. Conclusion: It is necessary to further research on the subject, since in the current literature few studies and data were found on the prevalence of vitamin B12 deficiency associated with anemia.
