Description:

Plasma renin activity (PRA) is higher in the renal vein of a kidney showing renovascular hypertension than in one that is not. If renovascular disease involves one kidney but not the other, a comparison of the PRA levels can indicate which kidney is affected, since the affected side will be high and the unaffected side low.
