Reexamination of the conditions for processing and storing of blood for plasma renin assay.
Reexamination of conditions for processing and storing blood for plasma renin assay confirmed that plasma can be stored at -20 degrees C for at least 4 weeks without significant changes in active renin level. The active renin concentration is increased by storage at 4 degrees C because of conversion from inactive renin.
