Term Description

Because of the confusion that occurs in countries that report results as both decimal fraction and percent, this property was created to represent decimal fractions that are reported without units.

Part Description

LP16418-3   Hemoglobin Barts
Hemoglobin Barts is a relatively common hemoglobin variant consisting of four gamma chains. Hemoglobin Barts is an extremely high affinity hemoglobin that is not effective at delivering oxygen to tissues. Hemoglobin Barts is only seen during the newborn period and usually indicates that one or more of the baby's alpha-globin genes are deleted, resulting in alpha-thalassemia. Alpha thalassemia is caused by deletions of the alpha globin genes on chromosome 16. Normal patients have four copies of the alpha-globin gene, 2 on each chromosome. A silent carrier will have one deleted alpha gene and usually result in a benign condition. Alpha thalassmia trait occurs when there are two deleted alpha genes, resulting in mild or no anemia with microcytosis and hypochromia. Hemoglobin H disease results from the deletion of three alpha genes with resultant moderately severe alpha thalassemia. Most patients are anemic and display some degree of splenomegaly. Fetal hydrops syndrome occurs when all four alpha genes are deleted. Fetal hydrops is not compatible with life and death occurs in utero or during early infancy.Carrier states for alpha thalassemia are very common in the African, Meditteranean and Asian populations. In general, only the loss of one or two genes is seen in African Americans. Asian and Meditteranean populations may have all types of alpha thalassemia.
