Galactose Screening, Blood

The Galactose Screening blood test measures the levels of galactose in your blood.

This test helps determine if there is a deficiency or impairment in the body's ability to break down galactose. It is done for the following reasons:

• To screen newborns for galactosemia, as early detection and treatment can prevent serious complications.
• To diagnose galactosemia in individuals with symptoms such as poor feeding, vomiting, jaundice, lethargy, and liver problems.
• To monitor galactosemia patients who are on a special diet and treatment to ensure that their galactose levels are within the normal range.

The Galactose Screening, Blood test is recommended for individuals who have:

• A family history of galactosemia.
• Symptoms suggestive of galactosemia such as failure to thrive, vomiting, lethargy, and liver problems.
• Been identified through newborn screening tests as having an increased risk for galactosemia.

Elevated levels of galactose may indicate the presence of galactosemia.

This test involves drawing a small sample of blood from a vein in your arm using a needle and a syringe. You may feel a slight pinch as the needle is inserted, but the procedure is generally quick and painless.

• There are no specific dietary restrictions or fasting requirements for this test.
• Inform your doctor about any medications, vitamins, or supplements you are taking as they may affect your test results.

Please reach out to your healthcare provider for any specific requirements.

Other tests that may be ordered alongside the Galactose Screening, Blood test include:

• Genetic testing to confirm the diagnosis of galactosemia and identify specific gene mutations.
• Liver function tests to evaluate liver health and function in individuals with galactosemia.

Galactosemia screening, galactose blood test

Galactosemia is a rare genetic disorder that affects the body's ability to process galactose. It is caused by a deficiency of enzymes needed to break down galactose. If left untreated, galactosemia can lead to serious complications such as liver damage, cataracts, and developmental delays. Early detection through newborn screening and lifelong management is crucial for individuals with galactosemia.
