Optimal range: 0 - 6.2 mmol/mol
The marker, 3-methylglutaconic acid in high values indicates a reduced ability to metabolize the amino acid, leucine. This abnormality is found in the genetic disease, methylglutaconic aciduria and in mitochondrial disorders.
Optimal range: 0 - 4.5 mmol/mol creatinine
The marker, 3-methylglutaconic acid in high values indicates a reduced ability to metabolize the amino acid, leucine. This abnormality is found in the genetic disease, methylglutaconic aciduria and in mitochondrial disorders.
Optimal range: 0.38 - 2 mmol/mol creatinine
The marker, 3-methylglutaconic acid in high values indicates a reduced ability to metabolize the amino acid, leucine. This abnormality is found in the genetic disease, methylglutaconic aciduria and in mitochondrial disorders.

3-Methylhippurate is a Xylene Metabolite.
Xylene is found in many solvents (paints, perfumes, etc.). Used in insecticide\pesticide application. Metabolized to Methylhippurate, which is measured in urine.
Optimal range: 0 - 74 mcg/g
Methylhippuric Acids (MHAs) are metabolites of xylene (dimethylbenzenes).
Xylenes are widely used as solvents in products including paints, detergents, pesticides, fuel, perfumes, and exhaust fumes.
The main effect of inhaling xylene vapor is depression of the central nervous system (CNS), with symptoms such as headache, dizziness, nausea, and vomiting.
Long-term exposure may lead to irritability, depression, insomnia, agitation, extreme tiredness, tremors, hearing loss, impaired concentration, and short-term memory loss.
A condition called chronic solvent-induced encephalopathy, commonly known as "organic solvent syndrome" has been associated with xylene exposure.
Optimal range: 60 - 1500 qmol/24 hours
Both 1-methylhistidine and 3-methylhistidine are histidine metabolites which have been proposed as markers of meat intake. Note that some confusion exists in the literature regarding the numbering of atoms in the imidazole ring of histidine – 1 versus 3 – and thus, there is caution with interpretation and clinical significance of these two markers.
3-methylhistidine is a constituent of actin and myosin, the contractile proteins of skeletal muscles. Urinary excretion of 3-methylhistidine may be a result of muscle breakdown or consumption of meat fibers. Unlike 1-methylhistidine, 3-methylhistidine has been shown to increase in fasting states indicating catabolism of muscle tissue. Therefore, this marker is more variable with regards to animal protein consumption.
Optimal range: 12 - 41 mmol/mol creatinine
Both 1-methylhistidine and 3-methylhistidine are histidine metabolites which have been proposed as markers of meat intake.
