Complete Microbiome Mapping (NutriPATH), NutriPATH

Optimal range:   0 - 5 x10^3 CFU/g

Klebsiella are non-motile, Gramnegative rods that belong to the Enterobacteriaceae family. Klebsiella bacteria are considered commensal but act as opportunistic bacteria in the GI tract. Klebsiellais a leading cause of hospital-acquired infections.

Klebsiella is part of the normal intestinal flora. The environment likely acts as a reservoir for human acquisition, either as colonization or infection. It is frequently found in water, sewage, soil, and plant surfaces.

Organix Comprehensive Profile - Urine, Genova Diagnostics

Optimal range:   0 - 1.5 mcg/mg creatinine

Kynurenate is product of the metabolism of L-Tryptophan and appears in urine in Vitamin B6 deficiencies. Your body needs vitamin B6 (pyridoxine) to utilize amino acids derived from dietary protein.

Nutritional Organic Acids (Urine) - DUTCH, Precision Analytical Laboratory – DUTCH Test Interpretation Guide

Optimal range:   0.8 - 4.5 ug/mg

Kynurenate is product of the metabolism of L-Tryptophan and appears in urine in Vitamin B6 deficiencies. Your body needs vitamin B6 (pyridoxine) to utilize amino acids derived from dietary protein.

Nutritional Organic Acids (Urine) - DUTCH, Precision Analytical Laboratory – DUTCH Test Interpretation Guide

Optimal range:   1 - 6.6 ug/mg

Kynurenate is product of the metabolism of L-Tryptophan and appears in urine in Vitamin B6 deficiencies. Your body needs vitamin B6 (pyridoxine) to utilize amino acids derived from dietary protein. Inadequate vitamin B6 is one factor that leads to increased concentrations of kynurenate and xanthurenate in urine. These products of amino acid breakdown cannot be further metabolized in the absence of vitamin B6.

3200 Metabolomix+ - FMV Urine, Genova Diagnostics

Optimal range:   0.44 - 5 Ratio

Because of the specific inflammatory component of quinolinic acid, as well as the potentially protective role of kynurenic acid peripherally, laboratories measure the ratio of kynurenic acid to quinolinic acid. This ratio can act as a measure of disturbed kynurenine pathway metabolism. It suggests that tryptophan is catabolized via the kynurenine pathway, rather than the serotonin pathway.

Metabolic Analysis Markers (Urine)

Optimal range:   0.44 - 5 Ratio

Kynurenic acid, which is derived from the processing of tryptophan, is converted to quinolinic acid in the presence of B6 or P5P. While kynurenic is calming, quinolinic is an excitotoxin that can over stimulate nerves.
