The Amino Acids Analysis measures 45 markers, including essential and non-essential amino acids and intermediary metabolites. Amino acids build and repair tissues, cause chemical reactions, transport nutrients, hormone and neurotransmitter synthesis, immune and detoxification functions, and more. Their critical role in human health makes them important in numerous clinical presentations.

Blood tests show what’s happening right now — but hair tells the story of months. Your hair locks in the record of your body’s mineral balance, nutrient status, and toxic metal exposure over time, making HTMA one of the most powerful tools for uncovering hidden patterns affecting your energy, mood, hormones, and resilience.

The Organic Acids Test provides a snapshot of the metabolism, based on a comprehensive assessment of 76 unique urinary metabolites. These small, discarded organic acid molecules are by-products of human cellular activity, the digestion of foods, and the metabolism of gastrointestinal flora. Specimens from individuals with a chronic illness, allergic condition, or neurological disorder often have one or more abnormal organic acids. Some organic compounds are produced by an overgrowth of gastrointestinal yeast and/or bacteria species due to impaired immune function or exposure to broad-spectrum antibiotics. Identification of yeast or bacterial overgrowth, paired with successful treatment can eradicate or markedly reduce patients’ symptoms and significantly increase the likelihood of recovery. The Great Plains Laboratory’s Organic Acids Test is the most comprehensive test of its kind. It evaluates yeast and bacterial overgrowth, vitamin and antioxidant levels, fatty acid metabolism, neurotransmitter levels, inborn errors of metabolism (including oxalate levels), mitochondrial function, oxidative stress, detoxification, and much more.
