How Clinics Use MyAgingTests

Patients bring the questions. We help you bring the evidence.

Preventive Medicine

Epigenetic markers are modifiable, which means biological age is a treatable metric, not just a number. Use GrimAge and other validated clocks in wellness visits and give patients concrete evidence of whether their interventions are working.

  • Baseline biological age assessment
  • Quarterly or annual follow-up testing
  • Patient-friendly results reports
Longevity Clinics

When patients ask "is this working?", you need data. Epigenetic testing gives you a measurable endpoint for treatment protocols, and our Research Hub gives you the evidence base to design them.

  • Multiple epigenetic clock options
  • Intervention effectiveness tracking
  • White-label reporting options
Clinical Research

Run clinical trials with biological age as an endpoint. Our platform handles participant management, sample tracking, and data collection for IRB-approved studies.

  • Multi-site study support
  • Data export for statistical analysis
  • Audit trails and compliance reporting
Corporate Wellness

Partner with employers to offer biological age testing as part of corporate wellness programs. Demonstrate ROI with aggregate health improvements.

  • Group enrollment and management
  • Anonymized cohort analytics
  • Custom wellness challenges

No New Test Required

Already Have Blood Work? Turn It Into a PhenoAge Report

Your patients' existing lab results already contain what PhenoAge needs. Upload the panels you have on file and get a biological age report back. No kit to ship, no second blood draw.

Developed in the Horvath lab at UCLA

PhenoAge came out of the work of Morgan Levine with Steve Horvath in the Department of Human Genetics at UCLA's David Geffen School of Medicine. Horvath co-authored both the 2018 papers behind it, in Aging and PLOS Medicine, so it shares its lineage with the epigenetic clocks the Clock Foundation was founded to advance.

Among the most validated measures we have

The same team validated it in PLOS Medicine, in a nationally representative cohort of 6,209 US adults with up to 17 years of mortality follow-up. Each additional year of phenotypic age carried roughly a 9% higher risk of death from any cause, and the measure held up across age, sex and racial subgroups, and among people whose standard results all looked normal.

Low cost, and nothing new to order

Nine markers from routine panels most of your patients have had within the last year. No new equipment, no specialist assay, no change to your draw protocol, and no waiting on a lab. At $29 an analysis it is the least expensive way to put a biological age in front of a patient.

How clinics are using it

Baseline every new patient

Turn the intake bloods you already take into a starting number, on day one.

Show an intervention working

Re-run after a protocol change and show the direction of travel, not just a panel that moved.

Prioritise who needs attention

Separate two patients of the same age whose risk is nothing alike.

A gateway to deeper testing

An affordable first step for patients not yet ready to commit to epigenetic testing.

1

Upload the labs you already have

Drop in the lab's PDF, a photo of the printout, or a spreadsheet. Results from any lab work. There is nothing to order and nothing to wait for.

The nine markers, all from the same draw: albumin, creatinine, glucose, hs-CRP, lymphocyte percentage, mean cell volume, red cell distribution width, alkaline phosphatase, and white blood cell count.

2

Confirm the values

The biomarkers are read off the report and shown back to you. Correct anything that needs it, in either US or international units, before the report is produced.

3

Get the report

Biological age against chronological age, where the patient sits relative to their peers, and which markers are driving the result.

4

Analyze longitudinal effects across multiple tests

Run each draw a patient has on file and you have a series, not a snapshot. Track biological age across visits, see whether it is moving with or against chronological age, and show what changed after an intervention. Patients with years of past blood work have a trend line from day one.

Existing Labs

PhenoAge Analysis

$29/test

Priced per analysis, so you can start with a single patient or work through your whole roster.

  • No kit or blood draw
  • PDF, photo, or spreadsheet
  • Works with past results
  • Reports in your dashboard

What the panel needs

Nine standard markers, typically a CBC with differential, a metabolic panel, and an hs-CRP from the same draw.

Frequently Asked Questions

What is biological age?
Biological age reflects how old your body actually is at a cellular level, based on biomarkers like DNA methylation patterns. Unlike chronological age (years since birth), biological age can be influenced by lifestyle, environment, and genetics. Two people of the same chronological age can have very different biological ages.
How is the test performed?
Our at-home collection kit uses a simple finger-prick blood sample. The kit includes everything you need with easy-to-follow instructions. Once collected, you ship it back using the included prepaid label for DNA methylation analysis.
How long until I get results?
Results are typically available within 3-4 weeks after your sample arrives at our lab. You'll receive an email notification when your results are ready to view in your secure online portal. Priority processing is available with our Complete Panel package.
Can I reduce my biological age?
Yes, and that's what makes epigenetic testing fundamentally different from genetic testing. Your DNA sequence is fixed, but your epigenetic patterns respond to how you live. Published research shows that changes in diet, exercise, sleep, stress management, and targeted interventions can measurably reduce biological age. Our platform helps you identify which changes have the strongest evidence and track whether they're working for you.
Can I upload my patients' existing epigenetic test data?
Yes! If your patients have had methylation array tests from TruDiagnostic, Elysium, or another provider that uses Illumina arrays, you can bulk-upload their raw IDAT files for free GrimAge compatibility evaluations. No new tests needed. Request the data files from the original provider and upload them here.
