Organic Acids, Plasma
Organic Acids, Urine assay, is the preferred test when screening for inherited disorders of metabolism. This plasma test is not as sensitive and will only detect the organic acids listed.
2-Keto-3-Methylvaleric Acid
Optimal range: 10 - 30 umol/L
2-Hydroxy-3-methylpentanoic acid or 2-hydroxy-3-methylvaleric acid (HMVA) is an organic acid generated by L-isoleucine metabolism. It is derived from the reduction of 2-Keto-3-methylvaleric acid (KMVA), possibly through the action of a lactate dehydrogenase.
LEARN MORE2-Ketoisocaproic Acid
Optimal range: 20 - 75 umol/L
2-Ketoisocaproic Acid is a B-Complex Vitamin Marker (Leucine catabolism).
2-Ketoisocaproic Acid is an abnormal metabolite that arises from the incomplete breakdown of branched-chain amino acids.
LEARN MORE2-Ketoisovaleric Acid
Optimal range: 3 - 20 umol/L
AKA: alpha-Ketoisovaleric acid
Alpha-Ketoisovaleric acid is an abnormal metabolite that arises from the incomplete breakdown of branched-chain amino acids.
LEARN MORE3-Oh-Butyric Acid
Optimal range: 0 - 30 umol/LAcetoacetic Acid
Optimal range: 0 - 66 umol/L
Acetoacetic acid (=acetoacetate) is a ketone body and a weak Beta-keto acid produced from acetyl-CoA in the mitochondrial matrix of hepatocytes.
LEARN MORECitric Acid
Optimal range: 0 - 100 umol/L
Citric acid, cis-aconitic acid, and isocitric acid are the first three metabolites in the Krebs Citric Acid energy production cycle, which operates in the mitochondria of your cells.
LEARN MORELactic Acid
Optimal range: 600 - 2600 umol/L
Formed from pyruvate in anaerobic or oxygen-starved (hypoxic) conditions to allow for ongoing production of ATP.
LEARN MOREPyruvic Acid
Optimal range: 20 - 140 umol/L
Pyruvic Acid feeds into the citric acid cycle & converts into acetyl CoA. Pyruvate is formed from carbohydrate via glucose or glycogen & secondarily from fats (glycerol) & glycogenic amino acids. Pyruvic acid is also formed from lactic acid with O2 and zinc.
LEARN MORESuccinic Acid
Optimal range: 16 - 25 umol/L
Succinate (or succinic acid) is an important metabolite that is involved in several chemical processes in the body.
