5-Hydroxyindoleacetic (5-HIAA) (Males Age 13 and Over)

Organic Acids Test (OAT) - Nutritional and Metabolic Profile, Mosaic Diagnostics

Optimal range:   0 - 2.9 mmol/mol creatinine

5-Hydroxyindoleacetic acid (5HIAA) is a breakdown product of serotonin that is excreted in the urine. Serotonin is a hormone found at high levels in many body tissues. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors.

Organic Acids Test (OAT) - Nutritional and Metabolic Profile, Mosaic Diagnostics

Optimal range:   0 - 28 mmol/mol creatinine

A metabolite produced by Aspergillus and possibly other fungal species in the GI tract. Prescription or natural antifungals, along with high-potency, multi-strain probiotics, may reduce overgrowth levels.

5-Hydroxymethyl-furoic acid

Organic Acids, Vibrant Wellness

Optimal range:   0 - 13.4 mmol/mol

5-Hydroxymethyl-furoic Acid is a naturally occurring human urinary metabolite, a nematicide, a bacterial xenobiotic metabolite and a fungal metabolite. It is a metabolite produced by Aspergillus and possibly other fungal species in the GI tract. Consider a Gut zoomer or fungal antibodies test in order to determine the root cause. It was first identified in the urine of a leukemic patient who was excreting an abnormal amount of its glycine derivative. Multi-strain probiotics can be supplemented to improve the condition.

5-Methyl Tetrahydrofolate

Folate Metabolism Profile (NutriPATH), NutriPATH

Optimal range:   6.6 - 39.9 nmol/L

Folates function as cofactors in the transfer and utilization of one carbon groups. These reactions are essential for the production of purines and pyrimidines for DNA synthesis. Folates also play a major role in the regeneration of methionine from homocysteine. In pregnancy, poor body stores of folates may lead to neural tube defects, such as spina bifida.

5-OH-indoleacetic Acid

Metabolic Analysis Markers (Urine)

Optimal range:   3.8 - 12.1 mmol/mol creatinine

5-OH-indoleacetic Acid is a breakdown product of serotonin that is excreted in the urine. Serotonin is a hormone found at high levels in many body tissues. Serotonin and 5-OH-indoleacetic Acid are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors.

5-OH-indoleacetic Acid

Metabolimix+, Genova Diagnostics

Optimal range:   3.8 - 12.1 mmol/mol creatinine

5-OH-indoleacetic Acid (5-HIAA) is a downstream metabolite of serotonin, which is formed from the essential amino acid tryptophan. Most blood serotonin and urinary 5-HIAA comes from serotonin formation outside of the CNS, primarily the liver and enterochromaffin cells in the gastrointestinal tract. Serotonin is further metabolized by monoamine oxidase to become 5-HIAA.

5-Oxoproline

Organic Acids, Comprehensive, Quantitative, Quest Diagnostics

Optimal range:   8 - 69 mmol/mol creatinine

Pyroglutamate (or 5-Oxoproline) is an intermediate in the glutathione metabolism and a marker of glutathione deficiency.

58 KD (IGG) Band

Lyme Testing

Optimal range:   0 - 0.001 Units

Two types of antibodies are detected in the Western blot test.

This particular marker is called 58 KD (IGG) Band and hence is a IgG antibody marker. IgG antibodies are a sign of an older infection. In contrast, IgM antibodies reflect a relatively recent infection. 

IgM antibodies usually disappear after eight weeks post-exposure. 
IgG remains in the serum for a very long time.
