Diagnose a broad range of metabolic disorders with a single test, Global MAPSTM

Let Global MAPS™ guide you to an answer.

Global MAPS™ is a large scale, semi-quantitative metabolomic profiling screen that analyzes disruptions in both individual analytes and pathways related to biochemical abnormalities. Using state-of-the-art technologies, Global Metabolomic Assisted Pathway Screen (Global MAPS™) provides small molecule metabolic profiling to identify >700 metabolites in human plasma, urine, or cerebrospinal fluid. Global MAPS™ identifies inborn errors of metabolism (IEMs) that would ordinarily require many different tests. This test defines biochemical pathway errors not currently detected by routine clinical or genetic testing.

IEMs are inherited metabolic disorders that prevent the body from converting one chemical compound to another or from transporting a compound in or out of a cell. These processes are necessary for essentially all bodily functions. Most IEMs are caused by defects in the enzymes that help process nutrients, which result in an accumulation of toxic substances or a deficiency of substances needed for normal body function. Making a swift, accurate diagnosis of an IEM and prescribing the appropriate diet or medication is critical in preventing brain damage, organ damage, and even death.

Global MAPS™ is a unique broad screening test that can detect disorders involving metabolism of amino acids, organic acids, fatty acid oxidation, vitamin cofactors, pyrimidine biosynthesis, creatine biosynthesis, and urea cycle metabolism, among other known disorders.
