Persistent tyrosinemia detected by thin-layer chromatography. The Southeast Asian Journal of Tropical Medicine and Public Health. 1999 ; 30 Suppl 2(): 151http://imsear.searo.who.int/handle/123456789/35275The Southeast Asian Journal of Tropical Medicine and Public Health.Screening for tyrosinemia is not routinely performed worldwide. Using a low expense thin-layer chromatography (TLC) for amino acids we detected a high frequency of transient tyrosinemia with secondary hyperphenylalaninemia in some newborns. Serum follow up showed the need to introduce adequate therapy in these babies.engChromatography, Thin LayerHumansInfant, NewbornNeonatal ScreeningPhenylalanine --bloodTyrosine --bloodTyrosinemias --diagnosisJournal Article
