Blood-based Mitochondrial Bioenergetic Profiling
Blood-based mitochondrial bioenergetics profiling is a minimally invasive, inexpensive, high throughput, rapid blood-based test to measure and monitor mitochondrial bioenergetic capacity. This test is being developed for presymptomatic risk determination and can be used as a screening tool across a broad array of age-related diseases including presymptomatic Alzheimer’s disease.
Researchers at Wake Forest Baptist Medical Center have developed a blood-based assay for measuring systemic bioenergetic capacity and mitochondrial function.
Simultaneous respirometric analysis of multiple blood cell types can provide up to 42 individual parameters that make up an individual’s bioenergetic profile.
The resulting profile reports on an individual’s bioenergetic capacity, providing a comprehensive, objective index of systemic mitochondrial health. This information can be used to assess health risks, support early diagnosis of diseases and inform on the prognosis of patients and their physiological ability to benefit from intervention. This informs clinical decisions regarding patient prognosis and recovery from specific interventions or care plans.
Traditional, tissue-based assessments of mitochondrial function are invasive, and the specific respirometric parameters associated with systemic bioenergetic decline are poorly defined. For these reasons, the clinical utility of mitochondrial respirometry has been limited.
Since the clinical assessment of mitochondrial function can be used for diagnostic and prognostic applications, as well as to test and develop pharmacological interventions aimed at improving mitochondrial function, a reliable, high throughput and non-invasive test has become a necessity.
