Citric Acid, Serum or Plasma
Also known as: CITRIC S
Use
This test measures the level of citric acid in serum or plasma, which can be used to evaluate a variety of conditions related to metabolism. Citric acid levels can provide insights into the function of the Krebs cycle, a vital metabolic pathway that produces energy in the form of ATP. It may be useful in diagnosing or monitoring metabolic disorders, assessing nutritional status, and other clinical conditions where metabolic imbalances are suspected.
