Positive screening for PA was defined as: plasma renin activity (PRA) less than or equal to 1.0 ng\/mL \u00b7 h with serum aldosterone more than or equal to 6 ng\/dL. PA was confirmed by a 24-hour urinary aldosterone excretion more than or equal to 12 mcg with urinary sodium more than 200 mmol.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>Only 33% (79\/241) of participants with an ARR more than 20 had a positive PA screen on HS. On LS, 56% (44\/79) of these participants no longer met criteria for positive PA screening. When compared with participants with positive PA screening on both diets, participants with a positive screen on HS but negative on LS exhibited a significantly higher PRA on both diets. Remarkably, of the 48\/79 participants who had PA confirmed, 52% had negative PA screening on LS. The distinguishing feature of these participants with \u201cdiscordant\u201d screening results was a larger rise in PRA on LS resulting in normalization of the ARR and higher Caucasian race prevalence.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions:<\/jats:title>\n                  <jats:p>Sodium restriction is recommended in hypertension; however, it can significantly raise PRA, normalize the ARR, and result in false interpretation of PA screening. Milder phenotypes of PA, where PRA is not as suppressed, are most susceptible to dietary sodium influences on renin and ARR. Optimal screening for PA should occur under conditions of HS.<\/jats:p>\n
