⚠️ Note: While Quest has locations in NY, NJ, and RI, Rejuvenate U is temporarily unable to process diagnostic test orders for residents of those states due to state regulations.

Lab work FAQs

Your lab results will typically arrive within two weeks, though processing time may vary based on the size and complexity of your panel. Rest assured, once your results are ready, they will be securely delivered to your email. No waiting rooms. No chasing paperwork. Just precision diagnostics at your fingertips.

Rejuvenate U is a cash-pay service. Our platform offers direct access to comprehensive testing without the limitations, denials, or delays imposed by insurance companies. If traditional insurance covered the kind of proactive, high-quality lab work we offer, Marek Diagnostics wouldn’t need to exist. 

However, many clients successfully use their HSA/FSA to cover their testing costs. Marek Diagnostics is partnered with TrueMed for convenient deployment of HSA/FSA funds at checkout.

Due to state regulations, Quest services are not available to residents of NY, NJ, or RI when ordered through our platform. If your address is in one of these states, you'll be notified at checkout and won’t be able to complete your order for restricted items.

You can still purchase:

  • Supplements, apparel, and other non-lab items

Not sure which items are restricted? The checkout system will alert you automatically, or you can contact our team for assistance.

If your panel Meets Treatment Requirements, you’re eligible to enroll into Guided Optimization, an exclusive program that connects you with:

  • Detailed, expert led lab analysis
  • A consultation with a Rejuvenate U coach and board-certified medical provider
  • A precision health optimization plan
  • Access to high-quality treatment options

If you’re unsure what to do with your results, Rejuvenate U is the bridge between lab results and achieving your goals.

No additional payment is required at the lab. Our expert-built panels include the venipuncture and if you’re building a custom panel or testing biomarkers individually, a $10 venipuncture fee will be automatically added at checkout.
