CPT® Code 82760

The CPT® Code 82760 refers to a laboratory test specifically designed to measure the level of galactose, which is a simple sugar molecule integral to the composition of lactose, a more complex sugar typically found in dairy products and infant formulas. This test is particularly significant in the context of diagnosing conditions related to galactose metabolism. Elevated levels of galactose in the blood, a condition known as galactosemia, or in the urine, referred to as galactosuria, can indicate potential metabolic disorders. These elevated levels may arise from an inherited genetic disorder affecting the enzyme Galactose-1-phosphate uridyltransferase, which is crucial for the proper metabolism of galactose. While testing for elevated galactose levels serves as a useful screening tool, it is important to note that it should not be relied upon as a definitive diagnostic measure for genetic disorders associated with galactose metabolism, such as Galactokinase deficiency (GALK), Galactose-1-phosphate uridyltransferase deficiency (GALT), or Epimerase deficiency (GALE). Additionally, elevated galactose levels may also be observed in other medical conditions, including severe hepatitis, newborn biliary atresia, and, in rare cases, galactose intolerance. The test is performed by obtaining a blood sample through a separately reportable venipuncture, while urine samples can be collected via random voiding or catheterization. The analysis of both plasma and urine samples is conducted using kinetic spectrophotometry, a method that allows for precise measurement of galactose levels.
