About this service

Advanced laboratory test involving full sequencing of the GALT gene to detect genetic mutations causing galactosemia, providing a definitive diagnosis for suspected cases or family genetic screening.

Indications for Testing

Clinical symptoms suggestive of galactosemia in infants.
Confirmation of positive results from newborn screening programs.
Genetic screening for families with a history of galactosemia.

What Does it Measure?

The test analyzes the entire coding sequence of the GALT gene.
Identifies pathogenic mutations affecting galactose-1-phosphate uridylyltransferase activity.
Differentiates between classic galactosemia and milder variants like Duarte.

Importance of Early Diagnosis

Prevents liver damage and organ failure through immediate dietary intervention.
Assists in providing accurate genetic counseling for future pregnancies.
Ensures specialized medical follow-up to mitigate growth and cognitive delays.

What is included?

✓Blood sample collection
✓Full gene sequencing
✓Detailed genetic report

Conditions and notices

Fasting is not required
Previous medical reports are recommended if available

Frequently Asked Questions

Short answers to the FAQs published with this service.

• What is GALT gene sequencing?

It is a precise genetic test that examines the entire GALT gene for mutations causing galactosemia, providing a definitive diagnosis.

• Is fasting required for this test?

No, fasting is not required for genetic sequencing; the sample can be collected at any time.

• When will the genetic results be ready?

Due to the complexity of genetic sequencing, results typically take between 7 to 14 business days.

• Can this test be done at home?

Yes, blood sample collection for this test is available as a home service through our platform for your convenience.

• Why would a doctor order this test?

It is usually ordered to confirm a galactosemia diagnosis following newborn screening or if symptoms like jaundice and feeding issues appear.

• Is this test sufficient for a diagnosis?

Yes, gene sequencing is the most accurate method to identify causative mutations and confirm the specific type of galactosemia.
