Citric acid analysis is a laboratory test used to determine the level of citric acid in a blood or urine sample. Citric acid is an essential biomolecule involved in the Krebs cycle, which is a key part of the body's energy production process. The results of this test are used to assess metabolic health and can help diagnose conditions such as metabolic disorders, kidney stones, and certain genetic disorders. Sample collection usually requires simple preparation, and the test is particularly useful for individuals with a family history of kidney or metabolic problems. Citric acid analysis also helps guide treatment and dietary choices to maintain overall health.
