Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Symptoms of severe metabolic acidosis
  • ✓Neurological impairment or developmental delay
  • ✓Unexplained lethargy or episodes of coma
  • ✓Elevated ammonia levels (hyperammonemia)
  • ✓Family history of N-acetylglutamate synthase deficiency or related metabolic disorders
  • ✓Suspected urea cycle disorder

In plain language

What this test helps you understand

This test helps identify mutations in the NAGS gene responsible for N-acetylglutamate synthase deficiency. Diagnosis is crucial for managing this metabolic disorder, which can cause severe health problems if untreated. It aids in understanding the genetic cause of symptoms and guiding appropriate medical care and dietary interventions.
The NAGS Gene N-Acetylglutamate Synthase Deficiency NGS Genetic DNA Test is a diagnostic tool used to identify metabolic disorders linked to N-acetylglutamate synthase deficiency. This condition affects the urea cycle and can lead to serious health issues if not diagnosed early. The test uses advanced Next-Generation Sequencing (NGS) technology to analyze the NAGS gene for specific genetic mutations. Early detection allows for timely management and treatment, potentially preventing severe complications associated with elevated ammonia levels. This test is particularly relevant for individuals presenting with symptoms suggestive of metabolic dysfunction or those with a family history of related disorders.

PreparationNo special preparation is typically required for this blood test. However, confirm with the laboratory for any specific instructions.
SampleBlood sample (usually collected in an EDTA tube). Confirm specific requirements with the laboratory before booking.
MethodologyNext-Generation Sequencing (NGS) of the NAGS gene.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test detects mutations within the NAGS gene. It may not detect all possible mutations, such as deep intronic mutations or large deletions/duplications, depending on the specific methodology used. A negative result does not completely rule out N-acetylglutamate synthase deficiency. Results should be interpreted in conjunction with clinical findings and other relevant tests.
