Reviews
What people praise
Affordable individual lab tests
Customers buying individual tests praise Marek’s pricing and the ability to order the bloodwork they want without adding a separate consultation to the purchase.
Stories
Ashley Rothstein
Building tests around her own health questions
Ashley used Marek to combine a comprehensive blood panel with additional markers and build custom panels for her husband. After three rounds of ordering and Labcorp visits between them, she found the process useful for accessing tests she wanted to explore beyond routine checkups.
ash-eats.comCorey Haines
Using repeat bloodwork to follow a broader care plan
Corey used bloodwork through Marek’s wider clinical program to identify priorities and revisit them over time. Alongside consultations and a broader treatment plan, repeat testing showed changes in several markers, helping him see where his routine was progressing and what still needed attention.

$149FAQs
Is the optional review a physician consultation?
The panel’s optional review is a health-coach session with a custom analysis report. It does not establish an ongoing treating-clinician relationship.
