Web16 de mar. de 1999 · Until recently, an indirect procedure for assessing residual PAH activity in vivo that was used widely is the phenylalanine-load test, which is based on the determination of the rate of clearance from blood of phenylalanine after the administration to a patient of a standard dose, usually 100 mg/kg of body weight, of the amino acid. This … Web24 de nov. de 2024 · Since the extraction ratio (ERPF/RPF) at low arterial PAH concentrations is not affected by age (92% in young and old subjects), PAH clearance can be used to reflect changes in renal blood flow with age.
