I begged my doctor for a serum amino acid test. And the pattern Of high amino acids I had on a normal protein diet were trademark low BH4. All of these were high. Arganine, tyrosine and phenylalanine. And my tryptophan was normal. All of my branched-chain amino acids were high as well telling me I had a B6 deficiency.
