Plasma renin activity and plasma prorenin assays.
Sensitivity and accuracy are essential features of an assay of plasma renin activity (PRA) because the normal concentration of PRA is only 1 pmol/L, and subnormal concentrations have diagnostic relevance. Conditions for blood collection need to be standardized but the conditions are not difficult for outpatients. For routine diagnostic purposes blood should be collected from ambulatory (ideally...
متن کاملDeterminants of Plasma Renin Activity
The plasma renin activity (PRA) is affected by a number of environmental factors. However, significant heritability has been shown for the activity. A hypothesis that a candidate regulatory single-nucleotide polymorphism, C-5312T, of human renin gene should have a significant effect on PRA was elucidated and updating of independent determinants of PRA was attempted. Cross sectional study.
متن کاملThe effect of aspirin therapy on the plasma renin activity in myocardial infarction
In this study, the changes of renin system activity and the effects of aspirin therapy on the plasma renin activity ( PRA) in myocardial infarction were investigated. Fifty nine patients with myocardial infarction were selected. By suppressed in the former group which was statistically significant ( p<0.01).
متن کاملPlasma renin activity in diabetes mellitus.
1. The plasma renin activity (PRA) was measured in 76 diabetic patients who were attending an outpatients clinic. Of these patients 16 had untreated hypertension and 28 had diabetic complications, which ranged from microaneurysms to renal failure and blindness. 2. Compared with age- and sex-matched normotensive control subjects, both normotensive and hypertensive diabetic patients had significa...
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....
