Galactosemia screen; GALT; Gal-1-PUT
The normal range is 18.5 - 28.5 U/g Hb (units per gram of hemoglobin).
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.
An abnormal result suggests galactosemia. Further tests must be done to confirm the diagnosis.
If your child has galactosemia, a genetics specialist should be consulted promptly. The child should immediately be placed on a no-milk diet. This means no breast milk and no animal milk. Soy milk and infant soy formulas are generally used as substitutes. For more detailed information, see the article on galactosemia.
