Official Description

Galactose

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The laboratory test for galactose levels is indicated in several clinical scenarios, particularly when there is a suspicion of metabolic disorders related to galactose. The following conditions may warrant this testing:

  • Galactosemia - A genetic disorder characterized by the inability to properly metabolize galactose, leading to elevated levels in the blood.
  • Galactosuria - The presence of galactose in the urine, which can indicate metabolic dysfunction.
  • Inherited genetic disorders - Conditions affecting the enzymes involved in galactose metabolism, such as GALK, GALT, and GALE deficiencies.
  • Severe hepatitis - A liver condition that may result in elevated galactose levels due to impaired liver function.
  • Newborn biliary atresia - A condition in infants that affects bile flow and can lead to metabolic abnormalities.
  • Galactose intolerance - A rare condition where the body cannot properly digest galactose, potentially leading to elevated levels.

2. Procedure

The procedure for testing galactose levels involves several key steps to ensure accurate results. The first step is the collection of a blood sample, which is performed through a venipuncture. This process involves inserting a needle into a vein, typically in the arm, to draw blood. It is important that this venipuncture is reported separately for billing purposes. In addition to the blood sample, a urine specimen is also required for testing. This can be obtained either through random voiding, where the patient provides a sample at any time, or through catheterization, which involves inserting a catheter into the bladder to collect urine directly. Once the samples are collected, they are subjected to analysis using kinetic spectrophotometry. This method allows for the precise measurement of galactose levels in both plasma and urine samples. Kinetic spectrophotometry works by measuring the change in absorbance of light as the reaction involving galactose occurs, providing a quantitative assessment of its concentration. This analytical technique is crucial for determining whether the galactose levels are elevated, which can indicate potential metabolic disorders.

3. Post-Procedure

After the galactose testing procedure, there are no specific post-procedure care requirements mentioned. However, it is essential for healthcare providers to monitor the patient for any potential reactions to the venipuncture, such as bruising or discomfort at the site of blood draw. The results of the galactose level test should be interpreted in conjunction with clinical findings and other diagnostic tests to provide a comprehensive assessment of the patient's metabolic status. Follow-up may be necessary to discuss the results and any further testing or interventions that may be required based on the findings.
