FAQs

Q1: How long does it take to get results from the Memphis lab?

Turnaround time varies by test type. Routine tests (e.g., CBC, lipid panel, glucose) are typically available within 24–48 hours. Specialized tests (e.g., genetic panels, toxicology, autoimmune markers) may take 5–10 business days. Urgent or STAT tests ordered by a hospital can be processed in as little as 4–6 hours. You can check estimated timelines when viewing your test order on QuestMyResults.

Q2: Can I get my results over the phone without registering online?

Yes. You can call the toll-free number 1-866-497-7448 and provide your identifying information (name, date of birth, test date) to receive your results verbally. However, for privacy and security reasons, results cannot be emailed or texted unless you have registered for a secure online account.

Q3: What if my results are flagged as “abnormal” or “out of range”?

Lab results are interpreted in context. An “abnormal” result does not always indicate disease. Many factors — including diet, medication, hydration, or recent illness — can affect levels. Always discuss your results with your ordering provider, who can determine if further testing or treatment is needed. The support team cannot interpret results for you — they can only confirm what was tested and provide the report.

Q4: How do I request a copy of my lab report for legal or immigration purposes?

You must submit a written request with a signed authorization form and a copy of your government-issued ID. You can download the form from the Quest website under “Request Records.” Mail or fax your request to the address provided in Section 2. Processing takes 7–10 business days. Rush service is available for an additional fee.

Q5: Can I speak to a specialist in a specific field, like genetics or oncology?

Yes. While general customer service agents handle most inquiries, Quest Diagnostics offers a “Clinical Consultation Line” for providers and patients with complex results. Call 1-800-697-9500 and ask to be transferred to the Clinical Support Team. A board-certified pathologist or laboratory specialist is available during business hours to discuss your results in detail.

Q6: Is there a mobile app for tracking my Memphis lab results?

Yes. Download the “Quest Diagnostics” app from the Apple App Store or Google Play. The app allows you to view results, receive push notifications when results are ready, schedule appointments, and message your provider securely.

Q7: What if I believe there’s an error on my lab report?

Contact the toll-free number 1-866-497-7448 immediately. The support team can verify your information, check for clerical errors, and initiate a retest if necessary. If a technical or analytical error is confirmed, Quest Diagnostics will retest at no charge and notify your provider.

Q8: Do you accept insurance? How do I know if my test is covered?

Quest Diagnostics accepts most major insurance plans, including Medicare, Medicaid, and private insurers. To verify coverage, call the billing support line at 1-866-308-8161 and provide your insurance information. You can also use the “Check Coverage” tool on the Quest website before your test.

Q9: Can I get my results in Spanish or another language?

Yes. When you call support, request a Spanish-speaking representative. You can also download translated versions of common lab reports in Spanish, French, Mandarin, and Arabic from your QuestMyResults account. For other languages, translation services are available upon request.

Q10: Is the Memphis lab accredited for international standards?

Yes. The Memphis lab is accredited by CAP, CLIA, and ISO 15189 — the gold standards for clinical laboratories worldwide. Results from this lab are accepted by governments, insurers, and medical institutions across North America, Europe, and Asia.
