The Comprehensive Organic Acids Quantitative Urine Test analyzes a broad spectrum of metabolites—organic acids—in urine to assess metabolic pathway function. By quantifying markers of detoxification, mitochondrial energy, and microbial metabolism, this test can help detect inborn errors, mitochondrial dysfunction, or dysbiosis.

The Amino Acid Analysis Plasma Test measures levels of essential and non-essential amino acids in blood to evaluate metabolic health, nutritional status, and inherited disorders. Abnormal results may indicate malnutrition, liver disease, kidney dysfunction, or inborn errors of metabolism. Doctors order this test for patients with developmental delays, unexplained weakness, or metabolic concerns. Results help guide diagnosis, treatment, and nutritional management.

The Lactic Acid Plasma Test measures lactic acid levels in the blood to help evaluate oxygen delivery, metabolic function, and tissue health. Elevated levels may signal hypoxia, sepsis, shock, heart failure, or severe infection, while mild increases can occur with intense exercise. Doctors use this test to assess critically ill patients, guide urgent treatment, and monitor metabolic or circulatory disorders for timely medical intervention.

The Oxalic Acid, 24-Hour Urine with Creatinine test is a diagnostic tool used to measure the levels of oxalic acid (oxalate) and creatinine in a patient's urine over a 24-hour period. Oxalic acid is a naturally occurring substance in the body, derived from dietary sources and metabolic processes. It plays a significant role in kidney function and metabolic health. Elevated levels of oxalate in the urine can contribute to kidney stone formation and may indicate underlying metabolic disorders. This test is particularly useful in assessing the risk of calcium oxalate kidney stones, evaluating kidney function, and diagnosing certain metabolic disorders. The inclusion of creatinine measurement allows for a more accurate interpretation of oxalate excretion by normalizing results relative to kidney function.

The Clostridium difficile Toxin/GDH Test with Reflex to Qualitative PCR screens for C. difficile toxins and GDH antigen, organisms often linked to antibiotic-associated diarrhea. Reflex PCR helps confirm diagnosis in unclear cases. This test aids in evaluating gastrointestinal function, infection risk, toxin activity, and systemic health effects of C. difficile–related disease.

The Lactate Dehydrogenase (LDH) Isoenzyme Panel measures total LDH and separates it into isoenzymes (LDH-1 to LDH-5) to identify tissue damage. LDH-1 is linked to heart, LDH-2 to blood, LDH-3 to lungs, LDH-4 to kidneys, and LDH-5 to liver and muscle. Elevated levels may indicate heart attack, liver disease, anemia, or cancer. Doctors order this test to pinpoint tissue injury, monitor disease progression, and guide treatment strategies.

The Comprehensive Fatty Acid Profile (C8–C26) analyzes 40+ fatty acids in serum—including medium, long, and very long chain species—to evaluate mitochondrial β-oxidation, peroxisomal disorders, essential fatty acid deficiency, or nutritional status. Abnormal patterns (e.g. elevated VLCFAs, altered w3/w6 ratios) help detect metabolic or peroxisomal defects and guide dietary or therapeutic interventions.

The Methylmalonic Acid (MMA) Blood Test measures MMA levels in the bloodstream to help detect vitamin B12 deficiency, often before anemia or neurological symptoms appear. Elevated results may indicate poor B12 absorption, pernicious anemia, or metabolic disorders. Doctors order this test when patients present with fatigue, neuropathy, or unexplained anemia. Results provide early insight into nutritional status, metabolic health, and treatment needs.

The Methylmalonic Acid Urine Test measures MMA levels to help detect vitamin B12 deficiency and assess metabolic health. Elevated MMA indicates impaired B12-dependent enzyme function, which may lead to anemia or nervous system damage. Doctors order this test to investigate unexplained fatigue, weakness, or neurological symptoms. It is often used with serum B12 testing for early, accurate detection and monitoring of deficiency.

The Nonesterified Fatty Acids Test measures circulating free fatty acids, important indicators of lipid metabolism and energy balance. Abnormal levels may signal insulin resistance, diabetes, obesity, or metabolic syndrome. This test supports evaluation of cardiovascular risk, liver function, and disorders related to fat mobilization, helping providers assess how the body regulates fat breakdown and energy use.

The Prostatic Acid Phosphatase Test detects PAP, an enzyme produced in the prostate, to provide information about prostate health and possible disease. Abnormal levels may suggest prostate cancer, metastatic spread, or benign prostate conditions. This test supports assessment of prostate function, systemic effects, and urologic health, offering insight into disease monitoring and progression.

The Uric Acid Test measures uric acid levels in blood to assess kidney function and detect gout, a form of arthritis caused by uric acid buildup. High levels may also signal kidney disease, kidney stones, or metabolic disorders, while low levels can occur with liver disease. Doctors use this test to investigate joint pain, swelling, or frequent urination, and to monitor treatment for gout, kidney stones, or chemotherapy-related complications.

The Valproic Acid Free Test measures the unbound, pharmacologically active fraction of valproic acid in the blood. This test helps evaluate therapeutic levels in patients taking valproate for epilepsy, bipolar disorder, or migraine prevention. Measuring free valproic acid is essential when total levels may be misleading due to altered protein binding, drug interactions, or hepatic dysfunction.
