Measuring molecules in context
Metabolomics studies small molecules in biological samples. Their patterns can reflect diet, metabolism, medication, microbial activity and other influences around the time of collection. No single sample provides an exhaustive or continuous reading of the body.
Genomics, clinical measurements and metabolomics answer complementary questions. Combining them may be useful, but more data do not automatically produce a more accurate prediction.
From analytical signal to biological meaning
An untargeted LC-MS analysis can produce many signals. A signal is not necessarily a uniquely identified metabolite, and an identified metabolite is not automatically a clinically validated biomarker. Collection quality, identification criteria, technical variation and validation all matter.
BioTwin’s publications describe individual profiling with dried blood spots and specific studies of breast-cancer classification and self-reported fatigue. Their results apply to the populations and methods studied. A retrospective association does not establish early detection in the general population, a cause of disease or the benefit of a screening program.
What the other data add
Wearables provide repeated observations of activity and physiology. Questionnaires document habits, symptoms and medication. Repeated samples add time. Together, these sources can help formulate and test hypotheses about individual variation.
Broader cardiovascular, neurological and endocrine applications require their own evidence and clinical validation. They should not be inferred from success on a different task.
TwinMe’s wellness interpretation remains separate from BioTwin’s medical research and authorized clinical pathways. A clinical use must be assessed for its specific indication, jurisdiction and setting.
