Mescreen is an at-home cellular energy test using a finger-prick dried blood spot. Your sample is analysed with a live-cell bioenergetics assay developed for NASA research (including the NASA Twins Study) to show how efficiently your mitochondria produce energy and handle stress. Use your results to tailor nutrition, supplements, training, sleep and recovery, and track progress over time. If your Mitochondria aren't optimal, neither is anything else.
At-home dried blood spot collection
Interactive dashboard showing your results in detail
20-minute results review with a mitochondrial specialist
Detailed action plan for the mitochondrial areas needing support
World’s first at-home mitochondria function test
Results in 20 to 24 days
From a finger-prick dried blood spot, your sample is run through a NASA Twin Study-validated live-cell assay to capture 11 core measures: Non-mito respiration, basal respiration, proton leak, ATP-linked respiration, spare capacity, glycolysis, oxidative phosphorylation, metabolic potential, ROS (oxidative stress), baseline network and stressed network. Use the results to fine-tune lifestyle, nutrition, supplements and recovery.
Mitochondria decline quietly. When cellular energy falls, you may feel flatter stamina, slower recovery, brain fog, poor sleep, cravings, or stubborn weight changes. Over time, lower energy resilience can support inflammation and raise risk for insulin resistance and metabolic syndrome.
