The renal excretion of cystathionine is not age-dependent when related to body surface. Regarding the urinary creatinine concentration as reference, the excretion of cystathionine in adults is lower than in infants and children. However, this is probably due to a higher urinary concentration of creatinine in adults compared to that in children. Premature infants excrete more cystathionine in their urine than mature infants. The same is true for premature infants on a methionine-enriched formula compared to premature infants on a low methionine formula.
当与体表面积相关时，胱硫醚的肾脏排泄不依赖于年龄。以尿肌酐浓度作为参考，成年人中胱硫醚的排泄量低于婴儿和儿童。然而，这可能是由于成年人尿液中肌酐浓度高于儿童。早产儿尿液中排泄的胱硫醚比足月儿多。与低蛋氨酸配方奶喂养的早产儿相比，富含蛋氨酸配方奶喂养的早产儿情况相同。
