Abstract

The diagnosis of the main hemoglobinopathies (HbS, HbC, HbE, heterozygous beta-thalassemia) is easy for laboratories using Hb electrophoresis and/or cation-exchange high performance liquid chromatography (CE-HPLC) methods. However, the diagnosis of alpha-thalassemias and of rare Hb variants is much more complex. Six French laboratories, forming together the "Pathologie héréditaire de l'érythrocyte" network, routinely practice the molecular diagnosis of hemoglobinopathies. These laboratories have shared their experiences to propose flowcharts for the phenotypical diagnosis and the molecular characterization of the main hereditary Hb pathologies. These flowcharts are applicable to any single patient with an adult erythropïesis (more than two-years-old), that is to say after the fetal to adult (gamma>beta) Hb commutation, when the HbF level is stabilized.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
