Description
Why It’s Done
The Galactose Total Test is done to:
• Screen for Galactosemia – a metabolic disorder where the body can’t break down galactose, found in breast milk and formula.
• Prevent Severe Complications – early detection allows for immediate dietary changes to prevent potentially life-threatening issues.
• Initiate Early Treatment – a galactose-free diet (usually avoiding milk and dairy) can help affected infants lead healthy lives.
Preparation
The test requires minimal preparation:
• Timing: Usually performed 24–48 hours after birth, ideally after the baby has had some milk feedings, so that galactose is present in the system.
• Sample Collection: A few drops of blood are collected via a heel prick and applied to a special filter paper for analysis.
• No special fasting or medication adjustments are required for the baby before the test
