Organic Acid Analysis

Test Information

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.

Turnaround Time

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

gas-liquid chromatography/mass spectroscopy (GC/MS)

Specimen Requirements

At least 10 ml of random catch urine is requested for this test.
