Galactosemia screen; GALT; Gal-1-PUT

Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight but may include:

• Excessive bleeding
• Fainting or feeling light-headed
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)

Early diagnosis is important, because the disease can be treated by removing dairy products from the diet.

Every state requires all newborns to be screened for this disorder. These screening tests are set to be very sensitive so they do not miss many infants with galactosemia. Because of this, false-positives can occur. If your child has an abnormal screening result, follow-up tests must be done to confirm the result.
