CPT® Code 82776

Galactose-1-phosphate uridyl transferase (GALT) is a crucial enzyme that plays a significant role in the metabolism of galactose, a sugar found in various foods. This enzyme facilitates the conversion of dietary galactose into glucose, which is essential for energy production within the body's cells. When GALT is absent or deficient, it leads to a condition known as classic type galactosemia, which is a hereditary disorder inherited in an autosomal recessive pattern due to mutations in the GALT gene. The absence of this enzyme can result in serious health issues, particularly in newborns, making early detection vital. The CPT® Code 82776 specifically refers to a screening test for the presence of GALT, which is typically performed as part of a broader panel of tests aimed at identifying metabolic disorders in newborns. This screening is essential for early diagnosis and management of galactosemia, allowing for timely interventions to prevent potential complications associated with the disorder.
