Leucine - Quantitative Urine 24 Hr

Leucine is an essential branched-chain amino acid that is crucial for protein synthesis, muscle repair, and various other functions in the body. The body cannot synthesize leucine, so it must be obtained through the diet. The Leucine Quantitative Plasma test and the Leucine Quantitative 24-hour Urine test measure the levels of leucine in the blood and urine, respectively. These tests can be essential for various clinical assessments, including nutritional evaluations, diagnosing metabolic disorders, and monitoring the effects of diet or medication on leucine levels.
