Newly developed IRMAs to measure the plasma concentrations of renin and prorenin were validated for clinical use and compared with a classical enzyme kinetic assay. The IRMAs involve two monoclonal antibodies, one that reacts equally well with renin and prorenin and one that recognizes renin well but prorenin only minimally. Prorenin reactivity with the second antibody was enhanced by adding the renin inhibitor, Remikiren, to plasma. The complex of prorenin with this active-site ligand undergoes a conformational change, whereby prorenin is converted into a form that cannot be differentiated from renin by the IRMA. The linear working range of the assay was 4.0-3000 mU/L. The concentration of prorenin was calculated by subtracting the assay result obtained without Remikiren (i.e., renin) from the result obtained with Remikiren (i.e., renin plus prorenin). No more than 2% of prorenin present in plasma was detected as renin. The interassay CVs for renin quantification were 18%, 13%, and 8% at low, medium, and high concentrations, respectively. The interassay CV for calculated prorenin was 8% at both low and high concentrations. The IRMA results were highly correlated with those of an enzyme kinetic assay in healthy subjects; in patients with such conditions as primary hyperaldosteronism, renovascular hypertension, and low-, medium-, and high-renin essential hypertension; and in women undergoing gonadotropin stimulation.
