About Impaired Glucose Tolerance

Impaired Glucose Tolerance is a prediabetic state of hyperglycemia that is associated with insulin resistance and an increased risk of cardiovascular disease.1 The condition occurs when blood glucose levels remain high for an extended period after oral ingestion of glucose but are not high enough to be diagnosed as type 2 diabetes. Impaired Glucose Tolerance can be assessed with a single fasted blood draw by measuring a panel of selected metabolites comprised of two small organic acids (α-hydroxybutyric acid (AHB) and 4-methyl-2-oxopentanoic acid (4MOP)), two lipids (oleic acid and linoleoyl glycerophosphocholine (LGPC)), a ketone body (β-hydroxybutyric acid (BHBA)), an amino acid (serine), a vitamin (pantothenic acid (vitamin B5)), and glucose.2

Metabolomics reveals biological insights otherwise unseen. For a successful metabolomics study, both small molecule discovery and the ability to dig deeper into specific biomarkers of interest are needed to uncover actionable insights that propel new therapeutic developments. A specific combination of liquid chromatography-mass spectrometry (LC-MS) technology and biochemical expertise is required to identify these biomarkers of interest and develop assays that are sensitive enough to explore them fully.

At Metabolon, we understand the crucial role glucose tolerance plays in diabetes, and we’ve established best-in-class expertise to assess this condition. This panel focuses on specific metabolites and their pathways that impact glucose tolerance. This panel can be used to track biomarkers and enhance biological understanding across preclinical and clinical research.

Impaired Glucose Tolerance Targeted Panel Applications


Diabetes is a serious metabolic condition affecting more than 37 million Americans and 460 million people worldwide according to the most recent report from the Centers for Disease Control. Despite being a worldwide epidemic, much remains unknown about individual risk factors for diabetes development, and research is currently being done to identify new and effective treatments for diabetes at all stages. By facilitating the assessment of specific metabolic pathways impacted by diabetes, targeted metabolomics can be a critical tool used to identify biomarkers of disease development for early intervention and novel targets to control disease progression, as well for the development of new pharmaceuticals with specific mechanisms of action.



Dysregulated metabolism is essential for the growth and proliferation of individual cancer cells, but the physiology of the patient is as much a part of the equation as the tumor. Metabolomics can both identify cancer-specific drug targets and assess the patient’s phenotype more broadly, addressing key questions such as: Who will respond to the therapy? How can we expand the pool of responders? How can we predict adverse events? Overall, metabolomics informs decision-making and positions development programs for success by providing a functional readout of the molecular phenotype.

Cardiovascular Diseases

Heart disease is a leading cause of death worldwide, and there are numerous factors that lead to this and other cardiovascular diseases (CVD). Metabolomics can illuminate cardiovascular disease at multiple levels. In preclinical studies, such as with cardiomyocytes or heart tissue from model organisms, understanding mitochondrial function, energetics, and redox status can drive critical insights into disease mechanisms. In human studies, metabolomics offers the opportunity to account for well-established CVD risk factors such as cholesterol and complex lipids, while simultaneously profiling thousands of other biochemicals in an unbiased fashion to enable the discovery of novel disease mechanisms and biomarkers.
