Hemoglobin Analysis in the First Year of Life.

摘要: Background and Objectives: In newborns infants during their first year of life, there is a dynamic change in the fraction hemoglobin (Hb). To apply Hb analysis as phenotypic diagnosis thalassemia infants, we need normal values each for reference. Methods: Seventeen cord bloods from deliveries were collected analysis. One hundred thirty seven pediatric outpatient clinic recruited categorized by ages into series short periods (month + 2 weeks). Both alpha beta carriers detected excluded. Samples with an level less than 10.0 g/dL also The proportion A ( b ), d F g ) was obtained high performance liquid chromatography analyzed according to its periods. Results: There 90 (58.4%) specimens left evaluation. percentage A, , gradually changed increasing age. 21.14 7.04% (mean SD) blood increased substantially 83.38 1.31% at sixth month. sustained thereafter. incremental pattern similar A. value 0.32 0.19% beginning reached plateau 2.78 0.25% started 78.39 7.59% decreased rapidly 6 months. Conclusions: data possibly can be applied quick guidance interpretation life.
