Frequently asked questions
Is ATP (plasma) high or low in ME/CFS?
Reduced. Studies summarised in the OSMF atlas report lower ATP (plasma) in ME/CFS than in healthy controls. Source: Saito et al. 2024.
What symptoms is ATP (plasma) associated with in ME/CFS?
The cited literature associates this marker with Energy deficit. These are population-level associations and do not mean the marker causes the symptoms.
Which test measures ATP (plasma)?
It is measured as a blood test (serum / plasma / whole blood). Many of the cited studies used research-grade assays, so clinical availability may vary.
Is one abnormal ATP (plasma) result diagnostic of ME/CFS?
No. No single biomarker is diagnostic of ME/CFS. ATP (plasma) findings come from group comparisons, overlap considerably between patients and controls, and vary with study design, timing and comparison group. A result should be interpreted by a clinician alongside symptoms, history and other tests.
Is ATP (plasma) specific to ME/CFS?
No. The same marker is also reported in Long COVID in this atlas, so it reflects shared biology (for example inflammation or vascular stress) rather than a condition-specific signature.
