How it works

You're measuring two different things, so it takes two samples: a blood draw for where your levels are now, and a saliva sample for your genetics.

Purchase your tests

After checkout, you'll get an email with your lab order form, next steps, and tips for collecting your samples.

Complete your blood draw

Visit a Quest location near you to give your blood sample. Results come back in about 14 business days.

Complete your saliva kit

We'll mail you a collection kit. Provide your saliva sample at home and mail it back in the prepaid packaging. Results take about 2 to 3 weeks.

Lab work FAQs

Please read our FAQs page to find out more.

How quickly will my lab results arrive?

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.

Does Marek Diagnostics accept insurance?

Marek Diagnostics 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.

Why can’t I order labs in New York, New Jersey, or Rhode Island?

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.

My panel Meets Treatment Requirements — what does that mean?

Marek Diagnostics is an extension of Marek Health, the leading health optimization platform designed to turn your results into informed action. 

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 Marek Health 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, Marek Health is the bridge between lab results and achieving your goals.

Do I need to pay a separate fee at the lab to get my blood drawn? 

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.
