Patient or order-specific updates may be requested directly and seamlessly from your Northstar Provider Portal. Alternatively, you may also contact Client Services at (833) 537-1819 or email support@northstaronc.com with the requested updated and patient/order details.
Please note that for compliance reasons, certain updates may require confirmation from the ordering provider or supporting documentation.
For Patients
Your healthcare provider will review your results with you once testing is complete. Results are sent directly to your provider for interpretation and discussion.
For billing or insurance inquiries, please contact our Patient Billing Team at (650) 501-0994.
Once your provider places your order, our team carefully begins testing your sample as soon as it arrives at our laboratory. Every step is handled with precision and care, and your results are securely sent to your provider once testing is complete.
Typical turnaround time is about a week from the date the sample is received at our laboratory. Some cases may vary depending on the type of test or documentation needed.
