Frequently asked questions

How does this test relate to my overall health?
This test focuses on genetic mutations that may influence how your body handles fluids and electrolytes. If mutations are found, they could help explain symptoms like kidney issues, fluid imbalances, or other related health concerns. Consult your healthcare provider to discuss how these findings may impact your care plan.
What if my test results are positive for a mutation?
A positive result means you have a genetic change in the SLC26A4 gene. This may require further evaluation by a genetic specialist or genetic counselor to understand its implications for your health. They can provide guidance on management, monitoring, or potential treatments tailored to your specific mutation.
Do I need to do anything special after the test?
No special actions are required after the test. Follow-up may include additional tests, consultations, or lifestyle recommendations based on your results and healthcare provider’s advice.
