Hemoglobin barts
Hemoglobin Barts (pronounced: hee-muh-gloh-bin baarts) is a form of hemoglobin that is found in abnormal amounts in newborns, especially those of Southeast Asian descent. It is named after St. Bartholomew's Hospital in London where it was first identified.
Etymology
The term "Hemoglobin Barts" is derived from the name of St. Bartholomew's Hospital in London, where the condition was first identified. The term "hemoglobin" is derived from the Greek words "haima" (blood) and "globin" (a type of protein).
Definition
Hemoglobin Barts is an abnormal form of hemoglobin that is produced in excessive amounts in the fetus and newborn. It is characterized by the presence of four gamma chains, instead of the normal two alpha and two beta chains. This results in a form of hemoglobin that has a high affinity for oxygen, which can lead to tissue hypoxia.
