The 3 Best Tests for Useful Health Data in 2026
I think its fair to say that 2025 was the year that getting labs done went fully mainstream.
Health data had already become popular, especially amongst tech enthusiasts. And now blood testing has become democratized and the general public is realizing the value of testing various biomarkers.
Ive been telling people to get bloodwork done for the better part of a decade, so this was all a welcome change.
Especially in light of the wearables trend.c. Which wearables are fun to have, but not essential.
In contrast, knowing your heart health, organ health, metabolic health, mitochondrial health, and genetic baseline, that data can be life changing and it gives you objective health KPIs to improve.
If I wanted to get the most comprehensive view of my life and create a 1 year plan to improve and optimize, these are the 3 I would recommend
Yes, I am once again telling you, GET THIS TEST DONE.
I will frame it this way
All traditional blood tests measure consequences.
All the “biomarkers” that are looked at are time dependent proxies for how your body has been functioning in the past months (and years).
This is useful, without question. I am not saying its bad or not worth doing. Im pointing out that its innately reactive.
Genetic Testing is the Opposite, It reframes all your actions on health into a Cohesive whole
Genetics are your source code. Knowing your genetic propensity shifts you from a paradigm of reaction and correction to one of proactive alignment.
Knowing your genetics can validate and give context to your health struggles.
It reduces the “trial and error” process that has been the default.
Most health journeys are 90% experimentation. This can be fun, but it also can be a waste of time.
Time is our most precious commodity
DNA is a technological breakthrough. I have no idea why people would NOT want to have it done, unless they are afraid of what the rest results might tell them.
Once you get the test done, its DONE. Its not something you need to repeat again.
Can you get all these blood tests yourself? Of course. Im not claiming Function has proprietary special tests.
What function does do is organize the data magnificently, and allow you to track all your numbers over time, and flags ones that need improvement, and it EXPLAINS what they all mean.
You get an education, you save time, and you can make more informed decisions.
These little guys do everything
Christ Masterjohn is a friend of mine, and he is brilliant in what he created with the Mitome test. For the first time ever, we can measure the function of our mitochondria and how well they produce energy (ATP).
I concur with Chris’s perspective that aging is aging is, fundamentally, the decline of energy production.
After age 18, mitochondrial function drops by roughly 1% per year. By identifying and fixing your specific inefficiencies, you aren’t just “feeling better”, you are effectively slowing the biological clock.

By analyzing the function of your Electron Transport Chain (ETC), the actual machinery producing 90% of your energy, the Mitome test tells you exactly how your cells are performing right now
When you know your specific mitochondrial “type” or dysfunction pattern, you can stop guessing with supplements. You don’t just take “CoQ10” because a podcast told you to; you take it because your specific assay showed a blockage that CoQ10 clears. This precision does away with the guesswork around supplements and nutrition interventions.
What does having better functioning Mitochondria do you?
A LOT
Steady, all-day energy without crashes
Elimination of brain fog and improved mental focus
Optimized hormone production (Testosterone, Cortisol)
Enhanced fertility and reproductive health (Egg quality/Sperm motility)
Faster physical recovery and reduced muscle soreness
Increased resting metabolism and effortless fat burning
Greater resilience to physical and mental stress
