Organic Acids Test

About Organic Acid Testing

The organic acids test (OAT) profile provides vital client information from a single urine specimen. It is valuable for determining:

  • Functional vitamin and mineral status
  • Amino acid insufficiencies like carnitine and NAC
  • Oxidative damage and antioxidant need
  • Phase I & Phase II detoxification capacity
  • Functional B-complex vitamin needs
  • Neurotransmitter metabolites
  • Mitochondrial energy production
  • Methylation sufficiency
  • Lipoic acid and CoQ10 status
  • Markers for bacterial and yeast overgrowth
  • Oxalates, fungal, and mold

What is an Organic Acids Test (OAT) for?

The organic acids test provides an in-depth view into the body’s cellular metabolic processes and its efficiency of metabolic function. Organic acids are metabolic intermediates that are produced in pathways of central energy production, detoxification, neurotransmitter breakdown or intestinal microbial activity. Marked accumulation of specific organic acids detected in urine often signals a metabolic inhibition or block. The metabolic block may be due to a nutrient deficiency, an inherited enzyme deficit, toxic build-up or drug effect. Several of the biomarkers are markers of intestinal bacterial or yeast overgrowth.

IMPORTANT TEST PREPARATION

READ CAREFULLY:
Collection Instructions

NOTE: Please review all instructions and collection kit components before starting your sample collection. DO NOT discontinue taking prescription medications unless directed by your physician.

Urine: 10 mL of first-morning urine before food or drink is suggested. Patients should avoid apples, grapes (including raisins), pears, cranberries, and their juices 48 hours prior to specimen collection. Avoid arabinogalactan, echinacea, reishi mushrooms, and ribose supplements for 48 hours before collection.

1. Save the cardboard box and place the gel pack flat into the freezer (for at least 4 hours) to ship the sample
back to us.


2. Send the sample off to the lab Monday through Thursday. Extra shipping charges will apply for Saturday
deliveries (Friday shipments), and the sample may become compromised due to the lab being closed
over the weekend.


3. Please check the specimen requirements below for patient preparation instructions.


4. Only use containers supplied by GPL to avoid contamination of specimens.


5. Females, please do not collect samples during menstrual cycle.


6. Limit liquid intake starting at 6pm the night prior to collection to avoid sample dilution. Urine must be yellow in color. If urine is clear the sample is too diluted. Discard diluted sample, rinse the collection cup in hot
