Measurement of plasma renin activity by semi-micro radioimmunoassay of generated angiotensin I.
A semi-micro method for determination of plasma renin activity (PRA) by radioimmunoassay of generated angiotensin I (AI) is described. The method permits measurement of PRA on 250 mul of plasma without loss of specificity, sensitivity, accuracy or preision. The small sample size has considerable application in terms of investigation of infants and young children. A reference range was establish...

متن کاملMeasurement of renin activity in human plasma.
• Many methods for measurement of renin activity have been described since Tigerstedt and Bergman first made an extract of kidney and showed that when injected it raised blood pressure. Those methods which rely on the rise of blood pressure following such injections suffer from three main disadvantages. First, the magnitude of response to a given dose may vary and tachyphylaxis can be elicited....
متن کاملMeasurement of plasma digoxin concentration by radioimmunoassay.
A rapid, sensitive, and precise method for measuring the plasma digoxin concentration has been developed with the radioimmunoassay technique. Seventy patients receiving digoxin were shown to have plasma digoxin concentrations between 0.4 and 5 ng./ml. Preliminary studies show that though there is a positive correlation between total daily dose and the plasma digoxin concentration, the relations...
