Marek Diagnostics empowers you to identify and monitor your health through comprehensive lab work. Our self-service platform allows you to select from a catalog of pre-designed lab panels or build
your own.

We offer diagnostic lab testing for informational purposes only. If you are interested in personalized care and oversight from expert health coaches and partnered medical providers, enroll in Expert Guided Optimization with Marek Health.

If you choose Marek Health’s Guided Optimization program, our providers may gather information about your medical history and current health to provide services to you. This information is called
“Protected Health Information” or “PHI” and includes personal identifying information such as your name, birthdate, and contact information, as well as information about your health, medical conditions, treatment, and prescriptions. Your consultations with a Marek Health provider may establish a doctor/patient relationship.

Marek Diagnostics is exclusive for US residents at this time. Hawaii and US territories are excluded.

We are unable to offer our services to those outside of the continental US. Furthermore, we are unable to work with non-US citizens.

All clients must be able to provide a valid US driver’s license or state issued identification to perform diagnostic testing.

These requirements apply to diagnostics, lab reviews, consultations, and other ancillary services. There is no workaround for this policy. We are unable to recommend other services in your area. We apologize for any inconvenience.

Marek Diagnostics is partnered with the Laboratory Corporation of America (LabCorp) for phlebotomy services. Before placing an order, please ensure there is a convenient LabCorp location near you by using the LabCorp diagnostic lab locator.

Marek Health is partnered with Laboratory Corporation of America (LabCorp), the world’s leading healthcare diagnostics company, to ensure the most accurate results possible. Lab requisitions ordered via Marek Diagnostics must be fulfilled and analyzed by LabCorp. Marek Diagnostics is not partnered with Quest Diagnostics or any other laboratory. 

No. While you have the option of making an appointment for your blood draw, LabCorp welcomes walk-ins. The blood draw itself takes about 10 minutes.

If you would like to make an appointment, you can do so here. 

Lab results typically arrive within 14 business days after your blood draw but certain results may take longer, depending on the complexity of the assays. We will forward your results to you as soon as they are available. 

Many of our panels utilize advanced testing methodologies that require more time to process. Marek Diagnostics refuses to compromise on the validity and reliability of testing assays for the sake of faster turnaround. We pride ourselves on our commitment to providing accurate and high-quality results.

Marek Diagnostics has no control over the speed in which your results are finalized. Results are forwarded within 24 to 48 hours of their arrival at Marek Diagnostics. 

Your personal healthcare provider can help you interpret the results. Marek Diagnostics is not a medical provider and does not establish a doctor/patient relationship with you. We cannot diagnose, prescribe, or provide medical advice. Self-service diagnostics do not include a one-on-one review of your results from Marek Diagnostics.

If you do not have a personal healthcare provider and you are interested in reviewing your results with a medical provider and receiving expert oversight and coaching, enroll in Expert Guided Optimization with Marek Health. If you choose Marek Health’s Guided Optimization program, please be aware that your consultations with a Marek Health provider may establish a doctor/patient relationship.

Marek Diagnostics will not communicate with insurance companies.

Despite the many benefits derived from advanced diagnostics and early detection, insurance companies consider many diagnostic services to be elective. 

Some clients have had success using FSA or HSA accounts towards their bloodwork. Marek Diagnostics can provide copies of invoices and lab requisitions if needed. However, we cannot provide procedure codes (CPT) or diagnostic codes (ICD-10) as we are direct pay and cannot seek reimbursement from your insurance company. Additionally we will not create atypical invoices or delay payment or create installment plans.

Promotion details and disclaimers
Discount and promotion codes are one-time use only. Not valid on prior purchases. Offer may not be combined with any other sale, promotion, or discount code. Void where prohibited, taxed, or otherwise restricted. Customers are limited to one discount or promotion code in their lifetime. Promotions have no cash value. Marek Health has the right to modify any promotion at any time. Other restrictions may apply. Offers only apply to the United States unless otherwise noted.

We are unable to provide diagnostic codes as we do not interface with insurance. Marek Diagnostics is a direct pay service with the financial responsibility being the client.

Your lab requisition form is valid for 6 months from the date of your order. If for some reason you are unable to schedule your draw within that time frame, please reach out to our customer service department to receive an updated requisition form – free of charge.

  • Please print out your lab requisition form. Though a physical copy of the requisition is not required, we recommend bringing one to help troubleshoot any potential issues. Keep a digital copy readily available if needed.
  • Bring your US driver's license or state-issued ID. No additional payment, form of ID, or insurance information is necessary.
  • Ideally, perform your labs in a fasted state (8 hrs of no food/drink) and avoid strenuous exercise for 24 hrs prior to your blood draw. We recommend scheduling your lab draw in the morning.
  • Drink plenty of water. Phlebotomists often recommend drinking two glasses of water prior to your draw to ensure sufficient blood flow.
  • Cease biotin (vitamin B7) supplementation 72 hrs prior to your blood draw. High levels of biotin in the blood may interfere with certain lab assays causing inaccurate results. Note: your multivitamin or hair-skin-nails vitamin may contain biotin.

For menstruating women who are assessing hormonal function, labs are ideally drawn during the mid-luteal phase of the menstrual cycle to assess ovulatory health. 

This is typically 7 days after ovulation or 7 days prior to the initiation of menses. If you don’t already track your menstrual cycle, consider utilizing a free app like Flo or purchasing a menstruation diary.

Rest assured, most clients report the process is no more painful than a tiny pinch. Please let your phlebotomist know if you are susceptible to fainting, syncope, or vasovagal response.

  • Lab requisition form signed by a partnered medical provider within our network.
  • Blood draw and urine sample collection fees. 
  • All lab testing fees.

Marek Diagnostics may use your PHI to order, receive and review your lab panel results without your written authorization. Please refer to Marek Diagnostics’ Notice of Privacy Practices and Terms and Conditions for additional information on how we use and disclose your protected health information.
