Plasma renin activity (PRA) has been measured by microassay on capillary and venous blood sampled simultaneously in 21 subjects; there is no significant difference between these two groups of PRA values. PRA values in normal infants, children and adults have been measured with this microassay and the results are similar to those previously published by authors using different radioimmunological assays.
