Hemoglobin F level in different hemoglobin variants
BACKGROUND Fetal hemoglobin (HbF) levels in different hemoglobin variants in Osogbo, Nigeria, were estimated using two principal methods of estimation using existing information for HbF concentration and distribution of various hemoglobin variants in the area, as well as diagnosed cases of thalassemia. Two hundred and sixty samples collected from HbSS, HbSC, HbAA, HbAS, and HbAC subjects were a...
متن کاملMeasurement of methemoglobin in neonatal samples containing fetal hemoglobin.
Because of the potential for methemoglobinemia during nitric oxide therapy in newborns, methods are needed to accurately quantify methemoglobin (MetHb) in the presence of the high concentrations of fetal hemoglobin (Hb F), bilirubin, and lipids seen in these patients. Spectral differences between fetal and adult Hbs invalidate assumptions of conventional multiwavelength Hb photometry, so we eva...
متن کاملHemoglobin Switching in Humans
Background: Understanding the mechanism of developmental regulation of hemoglobin switching has scientific as well as clinical relevance because of the influence of fetal hemoglobin (HbF) production in adulthood on the clinical manifestation of thalassemia and sickle cell anemia. We have previously found that the normal developmental patterns of globin gene expression are recapitulated in an ex...
متن کاملMeasurement of Hemoglobin A1c
Evaluation of glycemia is used for the diagnosis and management of patients with diabetes. Glucose and hemoglobin A1c (HbA1c) provide complementary information and both are used to assess an individual’s glycemic status. The concentration of glucose in the blood indicates the subject’s glycemia at the time of blood sampling. However, blood glucose concentrations are modified by numerous factors...
