Methods

  • RIA for angiotensin-1
  • plasma renin activity is measured indirectly by the ability of the patient's plasma to generate angiotensin-1*
  • simultaneous measurement of 24 hour urine Na+ & creatinine & serum/plasma Na+, K+ & creatinine are recommended
   angiotensinogen   ----- renin ------>   angiotensin-1
