Renin Activity, Plasma
Method Description Describes how the test is performed and provides a method-specific reference
The renin in plasma is allowed to act on the plasma's endogenous substrate, angiotensinogen, producing angiotensin I. This is measured by radioimmunoassay. Renin activity is expressed in ng of angiotensin produced per mL of plasma per hour of incubation.(Haber E, Koerner T, Page LB, et al: Application of a radioimmunoassay for angiotensin I to the physiologic measurements of plasma renin activity in normal human subjects. J Clin Endocrinol Metab 1969;29:1349-1355)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
