LOINC description : This test measures the phenylalanine to tyrosine ratio in children who have been diagnosed
with phenylketonuria and are on a therapeutic diet for their condition. The parent
of the patient collects the dried blood spot specimen at home and sends it to the
laboratory. This ratio is used together with the phenylalanine and tyrosine levels
to monitor the patient's progress. Note: different locations use different monitoring
analytes. In some states, tyrosine and phenylalanine levels are used in conjunction
with the succinylacetone level instead of the phenylalanine to tyrosine ratio.;
