Clear answers to common genetic-testing questions.
Practical information for patients, families and referring clinicians. For advice specific to you, speak with your treating clinician or contact GeneMetrics.
What people ask us most.
Testing can be technically complex. The explanation should not be.
What is non-invasive prenatal testing (NIPT)?
NIPT is a screening test that analyses cell-free DNA in a pregnant person’s blood to estimate the chance of selected chromosome conditions. It is a screening test, not a diagnostic test.
When can NIPT be performed?
Timing depends on the specific test. Many NIPT options can be performed from around 10 weeks of pregnancy. GeneMetrics confirms eligibility for the selected test before sample collection.
Does a high-chance NIPT result confirm a condition?
No. A high-chance screening result should be discussed with the treating clinician and may require diagnostic confirmation using an appropriate invasive test.
What is carrier screening?
Carrier screening looks for inherited variants associated with selected recessive or X-linked conditions. It can be considered before or during pregnancy and may help inform reproductive planning.
Can GeneMetrics help with fertility-related genetic testing?
Yes. GeneMetrics offers access to selected reproductive and fertility-related genetic and molecular investigations. The most appropriate test depends on clinical history and the question being investigated.
Do you offer hereditary cancer genetic testing?
GeneMetrics can facilitate hereditary cancer genetic testing when clinically appropriate. Because test selection and interpretation can be complex, results should be reviewed in clinical context and genetic counselling may be recommended.
What is pharmacogenomic testing?
Pharmacogenomics examines genetic variants that can influence how some medicines are metabolised or how a person may respond to them. Results should be interpreted by a qualified clinician alongside medical history and other factors.
Where are tests performed?
Depending on the investigation, samples may be processed locally or through selected specialist reference laboratories. GeneMetrics can explain the testing pathway, sample requirements and expected turnaround time for the specific test requested.
How long do results take?
Turnaround time varies by test and laboratory. GeneMetrics will provide the expected range for the selected investigation before testing. Complex or confirmatory testing may take longer.
Can a clinician refer a patient directly?
Yes. Referring clinicians can use the clinician portal to request access. Clinical functions are enabled only after professional verification.
How are my results shared?
Clinical results are never published on the public website. Patient and clinician access is separated from public content and requires verified identity.
Do you test children?
Some genetic tests may be appropriate for children when there is a clear clinical indication. Testing of minors requires appropriate consent and should be guided by a qualified clinician.
