Ship overnight frozen on dry ice Complete amino acid profile
Amino Acid Analysis, Special 4-5 drops of whole blood spotted on newborn screening filter paper card; air dried Ship by regular mail double enveloped and labeled Phenylalanine & tyrosine monitoring is provided for PKU patients
Metabolic Disease Profiles
(Mitochondrial Myopathy Profile or Myoglobinuria Profile or Glycogen Storage Disease Profile)
200 mgs. cardiac,  skeletal muscle, or liver tissue frozen in liquid nitrogen Ship overnight frozen on dry ice 50 mg. minimum for individual test requests; (Modified Mitochondrial Myopathy Screen requires 50 mgs. total)
