Mitochondrial Testing, Compared

How does mescreen™ compare to other tests?

Your cells run on the electron transport chain — four enzyme complexes and 100+ components that turn food and oxygen into energy. Most tests check a handful of genes or enzymes to infer function. mescreen™ measures the actual function and efficiency of that system, in real time, from a simple blood sample.

Results indicate dysfunctional mitochondria
Measures Oxygen Consumption Rate (OCR)
Measures Extracellular Acidification (ECAR)
Measures ROS production
Low intra-person variability

Technology developed for NASA

Genetic/DNA tests (e.g. SelfDecode) and microbiome tests (e.g. Viome) report predisposition or microbial composition — not the real-time functional output of your mitochondria. They fall under the "Genetic Testing" category above.

Legacy enzyme tests vs. functional measurement

Tests like Mitome™ and MitoSwab™ focus on a limited subset of enzymes. mescreen™ measures integrated function and efficiency across all complexes.

The Mitome / MitoSwab approach

Assesses the biochemical integrity of ~4–5 enzyme targets out of the 100+ components in the electron transport chain.

Doesn't measure electron flowNo direct assessment of electron transport or oxidative phosphorylation efficiency.
!Sample variabilityBased on cheek-cell samples, which can vary due to rapid cellular turnover.
Longer waitUp to 6 weeks for results, from a narrower functional dataset.

The mescreen™ advantage

Assesses integrated mitochondrial function and efficiency across all complexes, using peripheral blood as a systemic biological sample.

Dynamic measurementEvaluates cellular energy metabolism through live measures like OCR and ECAR.
Systemic viewA dynamic assessment of electron transport chain function and cellular energy balance.
Faster turnaroundResults generally available within 15–20 days of sample receipt.
