Circadian Variation of Plasma Oxalate in Normal Healthy Subjects

  • G. P. Kasidas

Abstract

The circadian variation of oxalate in urine has previously been reported (1–3) with urinary oxalate levels rising during waking hours and subsequently returning to basal levels during sleep (1). The advent of a routine and reliable continuous-flow enzymatic method (4) for measuring plasma oxalate prompted us to investigate whether such variations exist in blood.
