Mitochondria are tiny structures inside almost every cell in your body. They turn the food you eat and the oxygen you breathe into ATP, the energy your cells run on. A single cell can contain hundreds to thousands of them.

Almost everything your body does, from moving and thinking to recovering after a workout, runs on cellular energy, and mitochondria produce most of it. They also help manage oxidative stress and support communication between cells, so how well they work plays a big part in how energized you feel day to day.

Most routine blood tests look at markers circulating in your blood, not at how your cells actually make energy. mescreen™ looks at mitochondrial function directly, giving you a personal baseline you can track over time as you adjust sleep, nutrition, exercise or supplements with your provider.

Age, sleep, physical activity, nutrition, stress and overall lifestyle can all influence how efficiently your mitochondria work. That's why many people retest after making changes, to see how their cellular energy responds.

mescreen™ is for adults who want to understand their cellular energy, set a baseline to track over time, or see how lifestyle changes show up at the cellular level. Healthcare practitioners also use mescreen™ with their patients.

Many wellness tests look at genetics, hormones or general biomarkers. mescreen™ measures how your mitochondria are actually functioning, then pairs your report with a one-on-one consult so you understand what your results mean.

mescreen™ measures 13 core aspects of your mitochondrial function, meaning how well your cells produce and manage energy, from a small blood sample. Your results are summarized in four report areas and reviewed with you in a one-on-one consult.

No. mescreen™ is for general wellness and informational purposes only. It isn't intended to diagnose, treat, cure or prevent any disease, and it has not been reviewed by the FDA. Talk with your physician before changing medications, diet or exercise.

Your sample is analyzed in a laboratory using scientific methods from published NASA research, and every result goes through laboratory validation and quality checks before your report is released. mescreen™ is a wellness test, not a diagnostic test, so your results are best used as a baseline you track over time and discuss with your provider.

No prescription is needed to order a mescreen™ test.

Your kit should arrive within 7 days of your order. Collection takes under 10 minutes. Once your sample arrives at the laboratory, results are generally ready within 2–3 weeks.

The at-home collection takes less than 10 minutes and is simple to complete.

You’ll receive your comprehensive results and mescore™ within 2-3 weeks of our lab receiving your sample.

A 20-minute one-on-one session with a mescreen™ expert who explains your results and provides personalized recommendations.

No. mescreen™ is not covered by insurance.

When you're starting or adjusting a plan with your practitioner, retesting every 3–4 months is common. Once your plan is settled, many people test every 6–12 months.

Your individual results stay private to you. We don't sell your test results or use them for advertising, and you decide who else sees them, such as your own provider. See our Privacy Policy for details.

Delivered vs. Received

There is typically a delay between the time a sample is marked as "delivered" on the tracking information and the time it is scanned as “received” by the lab. Occasionally, this delay can take up to 2 weeks. A kit is marked as “received” by our system when it is physically opened at the lab and the kit barcode is scanned - this process is referred to as accessioning.

It is not unusual for kits shipped at the same time to be received at the lab at different times. You will receive an email when our laboratory completes the accessioning process and scans your kit barcode. The status of your sample will also update on your profile homepage.

If the laboratory receives a sample kit that has not yet been registered to an account, the kit barcode and registration instructions will be sent to the email address associated with the order.
