The test requires blood, extracted DNA, or one drop of blood on an FTA card.
Do I need to fast before the test?
No, fasting is not required for this genetic test.
What do the results mean?
Results indicate whether pathogenic mutations in the GNAL gene are detected, which can confirm a diagnosis of dystonia and guide treatment.
Can the test detect all mutations in the GNAL gene?
The test is comprehensive but may not detect all possible genetic variants; clinical correlation is recommended.
Who should consider this test?
Individuals with symptoms of dystonia, family history of movement disorders, or unexplained neurological issues should consider this test.
How accurate is the test?
The test uses advanced NGS technology for high accuracy, but results should be interpreted by a healthcare professional in the context of clinical findings.
