Preliminary screening of amino acids excretion in the urine of newly born babies.

The paper attempts to characterize the qualitative as well as quantitative estimations of aminoacids in the urines of new born babies using two dimensional paper chromatography. The objective of this investigation was to know the extent of amino acid defects in these samples and to correlate such defects with the physical abnormalities in infants. Based on the overall results, it is inferred that phenylalanine excreted in the urine gave a positive response with PKU test and some particular amino acids are identified and estimated in the urine of new born babies to confirm the diagnosis of phenylketonuric patients.
