title: [Circadian rhythms in urinary coproporphyrin and delta-aminolevulinic acid].
abstract: The circadian rythm concerning the excretion of urinary metabolites ALA and CP was investigated. More ALA and CP are excreted in the urine during the day than the night. This phenomenon is more evident with CP. The sampling of urine for biochemical control of saturnism is discussed and the sample collected after 24 h was chosen.
