Metabolomics is a branch of science concerned with the study of metabolic processes in the body through the analysis of metabolites. It involves the determination of specific chemical markers that are formed during reactions occurring in the cell in both physiological and pathological states. It allows the detection of metabolic changes resulting from:
  • diseases (oncological, metabolic, cardiovascular, neurodegenerative)
  • exposure to toxic or pharmacological substances
  • changes in diet
Metabolomics is one of the 'omics' fields of biology, alongside genomics, transcriptomics, and proteomics. The first publications in this field appeared in 2002, and it is currently developing rapidly.
Metabolomics uses various analytical methods such as mass spectrometry, gas, or liquid chromatography, which allow the identification of many metabolites and determine their quantitative changes, thus enabling a better understanding of processes occurring in organisms.
Thanks to the vast knowledge and dedication of the Research and Development Department, numerous proprietary methods have been developed and validated for routine diagnostic use. Some methods, such as the determination of tryptophan or arginine metabolite profiles, remain in the realm of scientific collaboration, as their clinical interpretation is not yet known despite our ability to measure them.
