Amino Acids (Urine) by The Great Plains Laboratory
1-Methylhistidine
Optimal range: 70 - 280 qM/g creatinine
It is a component of the dietary peptide anserine. Anserine is beta-alanyl-1-methyl-L-histidine, and it is known to come from chicken, turkey, duck, rabbit, tuna and salmon.

Optimal range: 55 - 1100 qM/g creatinineAlanine
Optimal range: 130 - 600 qM/g creatinineAlpha-amino-N-butyrate
Optimal range: 5 - 72 qM/g creatinine
Alpha amniobutyric acid (AABA), also known as Alpha-amino-N-butyric acid (A-ANB), is an intermediate formed during the catabolism of methionine and threonine. Increases in AABA occur secondary to elevations of either methionine or threonine. AABA becomes propionic acid via alpha-ketobutyric acid in the presence of adequate amounts of thiamin, vitamin B2(as FAD), vitamin B3(as NAD), lipoic acid and magnesium. Deficiencies of any of these, or vitamin B6, could cause increases in AABA. Elevated or decreased levels of the amino acid may indicate a congenital enzyme defect.

Optimal range: 6 - 72 qM/g creatinine
Alpha-aminoadipic acid (a-Aminoadipic acid) is an intermediary metabolite of lysine (primarily) and of tryptophan.

Optimal range: 0 - 50 qM/g creatinineCitrulline
Optimal range: 1 - 30 qM/g creatinineCreatinine
Optimal range: 30 - 225 mg/dL
The urinary creatinine concentration (CC) represents the actual creatinine concentration in the specimen that was submitted.
Under normal conditions, the rate of excretion of creatinine is quite constant and highly correlated with lean body mass (muscle). However, the CC can vary significantly as a function of urine volume.
LEARN MORECystathionine
Optimal range: 8 - 50 qM/g creatinineCysteine
Optimal range: 25 - 73 qM/g creatinineCystine
Optimal range: 30 - 105 qM/g creatinineEthanolamine
Optimal range: 120 - 440 qM/g creatinineGamma-aminobutyrate
Optimal range: 0 - 7 qM/g creatinine
Gamma-aminobutyrate (GABA) is the major inhibitory neurotransmitter found in the CNS and, as such, is important for balancing excitatory action of other neurotransmitters.
LEARN MOREGlutamate
Optimal range: 10 - 52 qM/g creatinineGlutamine
Optimal range: 155 - 650 qM/g creatinineGlutamine/Glutamate
Optimal range: 3 - 120 RatioGlycine
Optimal range: 350 - 3500 qM/g creatinineHistidine
Optimal range: 350 - 1700 qM/g creatinineHomocystine
Optimal range: 0 - 1 qM/g creatinineHydroxyproline
Optimal range: 0 - 45 qM/g creatinine
Hydroxyproline is a collagen related amino acid. Hydroxyproline is a nonessential amino acid, which means that it is manufactured from other amino acids in the liver. Hydroxyproline is necessary for the construction of the body’s major structural protein, collagen. Hydroxyproline is present in essentially all tissues and all genetic types of collagen.

Optimal range: 56 - 320 qM/g creatinineTryptophan
Optimal range: 20 - 100 qM/g creatinineTyrosine
Optimal range: 28 - 120 qM/g creatinine
Tyrosin is the non-essential amino acid precursor for dopamine, norepinephrine and epinephrine. Tyrosine hydroxylase converts tyrosine into the dopamine precursor L-DOPA; BH4, Vitamin D and iron are cofactors for that enzymatic activity.
Tyrosine enhances cognitive performance, energy, and alertness, and improves memory after sleep deprivation.
