title: [Lysine in human biologic fluids and tissues: reference values, physiologic variations and interferences].
abstract: The authors present here the published values of lysine in some biological fluids, plasma, urine, CSF, amniotic fluid, aqueous humor, sweat. The plasma levels are lower in newborn infants than in adult subjects. The urinary excretion of lysine is high in the first pregnancy, the lysine concentration of amniotic fluid decreases progressively. A sex difference has been described in CSF: values higher in men. Changes occur in lysine concentrations when samples are not prepared for analysis immediately after collection and certain drugs interfere with analysis.
