Resources for Physicians
The metabolic laboratory routinely performs qualitative detection and quantitative determination of diagnostic markers based on a variety of chromatographic methods, particularly Gas chromatography/Mass spectrometry (GC/MS) and tandem Mass spectrometry (MS/MS).
We offer expert diagnostic testing of organic acidemias, fatty acid oxidation defects and amino acids. We are constantly adding new diagnostic tests that will help physicians in diagnosing and managing metabolic disorders. Consultative services are also available on request to physicians to aid in the proper management of these rare conditions.
