Step 2: Complete your lab draw

Most appointments take 15-20 minutes. An experienced phlebotomist will draw blood samples covering 80+ biomarkers across 13 different health panels. 


How to prepare:

You’ll receive clear instructions via email on how to modify food, drink, or supplements before your lab draw. On the day of your appointment, you just need to bring a copy of your lab requisition and photo ID.

Step 3: Get your results

After your labs are processed and reviewed, your results will be delivered through our secure online portal.


A deep dive into biomarkers:

For each biomarker, you’ll get detailed notes for explaining what it measures, how it fits into the broader picture of your health, how symptoms may manifest, what might be causing issues, and supplements that may help.

Step 4: Add-on Clinical Review Visit

Our Clinical Review Visit is where Longevity Labs becomes more than a lab test. Your board-certified Parsley clinician reviews your results in the context of your symptoms, history, and goals, then gives you a clear, personalized action plan for your health.


Why this experience makes all the difference:

Turn your labs from numbers into action. Our functional medicine clinicians are uniquely qualified to interpret your advanced labs results and guide your next steps.
