Test Overview & Methodology
The Galactosemia (GALT) Gene Mutation Detection Test is a definitive molecular diagnostic examination that identifies pathogenic variants in the GALT gene responsible for classic galactosemia. Using PCR and Sanger sequencing of genomic DNA extracted from a whole blood sample, it delivers laboratory-confirmed results within 15 business days to guide immediate metabolic management in neonates and at-risk family members.
| Feature | Our GALT Gene Test | Closest Alternative (Enzyme Assay) |
|---|---|---|
| Methodology | PCR + Sanger Sequencing (Gold Standard) | GALT Enzyme Activity (RBC) |
| Diagnostic Precision | 99.9% mutation-specific sensitivity | May be affected by transfusions, false positives |
| Turnaround Time | 15 Business Days (sample by 11 AM daily) | 7-10 days (limited by sample stability) |
| Clinical Utility | Carrier screening & definitive diagnosis | Biochemical suspicion only |
Physician Insight & Safety Protocols
"Timely genetic confirmation of pathogenic GALT variants is critical to prevent life-threatening neonatal metabolic crises. While this test provides precise molecular data, comprehensive clinical correlation with biochemical markers and dietary response remains essential for a safe management plan. I strongly advise discussing all results with your metabolic specialist or geneticist."

Advisory & Exclusion Criteria
Medication Advisory
Do not discontinue prescribed dietary or medication protocols without consulting your treating physician. Genetic testing is a diagnostic aid, not a replacement for clinical management.
Exclusion Criteria
- Blood transfusion within the last 120 days – donor leukocyte DNA may interfere with accurate genotyping.
- Inability of the patient or legal guardian to provide valid written informed consent.
- Incomplete or unsigned Genomics Clinical Information Requisition Form (Form 20).
Seek emergency medical attention if a neonate displays persistent vomiting, jaundice, lethargy, poor feeding, or signs of sepsis, as these may indicate an acute galactosemia crisis.
Patient FAQ & Clinical Guidance
1. What does the GALT gene mutation test detect?
This test identifies specific pathogenic mutations in the GALT gene that cause classic galactosemia. The assay sequences the entire coding region of the GALT gene to detect known variants such as Q188R and K285N. A positive result confirms the diagnosis, enabling immediate initiation of a galactose-restricted diet to prevent irreversible liver, brain, and ocular damage.
2. How is the sample collected and what preparation is required?
A certified phlebotomist collects 4 mL of whole blood in an EDTA lavender-top tube. No fasting or special preparation is needed. Our VIP mobile phlebotomy team will visit your home between 8 AM and 11 PM, ensuring the sample is maintained at 2-8°C during transport. The mandatory Genomics Clinical Information Requisition Form (Form 20) will be provided for you to complete during the appointment.
3. Who should consider this test and why?
Neonates with jaundice, vomiting, or failure to thrive, and families with a known history of galactosemia should prioritize this test. It is also recommended for parents planning a pregnancy who carry a known family mutation, or for diagnostic confirmation in newborns with positive newborn screening results. Early detection prevents acute metabolic crisis and long-term intellectual disability.
