Organic Acids

Test description Organic acids are involved in many metabolic processes within the cell. With certain genetic disorders, there may be abnormal concentrations of organic acids that are present in blood or other body fluids. Organic acid analysis is usually carried out on urine since many of the abnormal compounds will not be observed in other tissues.
Indications Disturbances of organic acid metabolism may be suspected in infants or children with feeding difficulties, failure to thrive, growth delay, developmental delay, seizures, unusual body odor, hypotonia and/or hyperammonemia.
Methodology Analysis will be done by gas-liquid chromatography/mass spectroscopy (GC/MS) with identification of elevated and/or abnormal organic acids. For some organic acids, quantitation is offered.
Associated Tests Organic acid analysis is also part of our Biochemical Genetics Profile.
