Because of the enormous number of these diseases the wide range of systems affected badly, nearly every "presenting complaint" to a healthcare provider may have a congenital metabolic disease as a possible cause, especially in childhood and adolescence. The following are examples of potential manifestations affecting each of the major organ systems. Diagnostic
Dozens of congenital metabolic diseases are now detectable by newborn screening tests, especially expanded testing using mass spectrometry. gas chromatography–mass spectrometry-based technology with an integrated analytics system, which has now made it possible to test a newborn for over 100 mm genetic metabolic disorders. Because of the multiplicity of conditions, many different diagnostic tests are used for screening. An abnormal result is often followed by a subsequent "definitive test" to confirm the suspected diagnosis. Common screening tests used in the last sixty years:

Ferric chloride test (detects abnormal metabolites in urine)
Ninhydrin paper chromatography (detects abnormal amino acid patterns)
Guthrie test (detects excessive amounts of specific amino acids in blood) The dried blood spot can be used for multianalyte testing using Tandem Mass Spectrometry (MS/MS). This given an indication for a disorder. The same has to be further confirmed by enzyme assays, IEX-Ninhydrin, GC/MS or DNA Testing.
