Evaluation of the neonatal screening in the identification of hemoglobin s: biological collection

Background: The aim of this manuscript was to evaluate the neonatal screening in the identification of hemoglobin S specifically the biological collection in the state of Mato Grosso do Sul, Brazil, in the period from 2011 to 2015. Methodology: This is a descriptive study that analyzed information about the National Neonatal Screening Program for hemoglobinopathies contained in the database of the Research Institute, Study and Diagnostics of the Association of Parents and Friends of the Exceptional in Mato Grosso do Sul, Brazil. The variables studied were the year of cancellation of the sample; total number of screenings; number of samples canceled due to failures in the collection of the screening; reasons for cancellation of samples; number and results of new samples resulting from cancellation. For the interpretation of the studied variables, we used the descriptive statistical analysis. Results: The failures identified in the neonatal screening are related to the collection technique, sample with more than 30 days of harvest and those in duplicate. Of the total of the canceled samples 55% were collected again. Conclusion: The neonatal screening process requires careful monitoring due to the complexity of sickle cell disease. Permanent education actions are suggested to health professionals, as well as research that identifies the determinants for the National Neonatal Screening Program in Mato Grosso do Sul to reach the 100% coverage ratio.
