- Advanced detection: By interrogating genes for complex variants, we can identify the underlying causes of conditions that may otherwise be missed.
CLINICAL EXPERTISE
- Thorough analysis: We classify variants according to our custom adaptation of the most recent guidelines. We then leverage our rich internal database for additional interpretation evidence.
- Customized care: Our experts review all test results and write reports in a clear, concise, and personalized way. We also include information for research studies in specific clinical situations.
- Impactful discovery: Our researchers continue working to find answers even after testing is complete.
