erythroblastosis
Noun: A blood disorder characterized by the abnormal presence of erythroblasts (immature red blood cells) in the circulating blood. This condition is typically associated with hemolytic disease, often due to blood group incompatibility between a mother and fetus.
The term is used in medical contexts to describe a specific pathological state of the blood. * The pediatrician diagnosed the newborn with erythroblastosis fetalis. * Erythroblastosis is a serious condition that requires immediate medical intervention.
- Erythroblastosis fetalis: This is the most common specific usage, referring to the hemolytic disease in a fetus or newborn, most frequently caused by Rh factor incompatibility.
- The mother's Rh-negative status put the baby at risk for erythroblastosis fetalis.
- Erythroblast (noun): An immature, nucleated cell that develops into a red blood cell.
- Erythroblastotic (adjective): Pertaining to or affected by erythroblastosis.
- The erythroblastotic infant was treated with phototherapy.
- Hemolytic disease of the newborn (HDN) (This is a broader term that often encompasses erythroblastosis fetalis).
The term "erythroblastosis" has a highly specialized meaning in hematology and pathology. It does not have common idiomatic or figurative uses. Its core meaning is consistently tied to the pathological presence of immature red blood cells in the bloodstream.
