Guest guest Posted July 25, 2012 Report Share Posted July 25, 2012 I'm a little confused by plasma renin measurememts and hope someone here cah help. All of my test to date have been for " Plasma Renin Acitvity " with the results in nanograms per mililiter per hour (ng/ml/hr) For each test my results have been reproted at <0.6 which I understand to be the minimum detectable level for the test. Another members recent post had a post had renin at 0.38 with norms of 0.25-5.89 So are thier two tests, or is this just different labs standards? Also what exactily is " activity " in hours measuring Thanks for any help Mike Quote Link to comment Share on other sites More sharing options...
Guest guest Posted July 25, 2012 Report Share Posted July 25, 2012 Some measure activity (preferred) ng/ml/hr which measures how much AI generated in 1 hr of incubation and others measure the renin concentration itself.So you need to know what the normals are for that lab under the conditions that pertained to when it was measured.Also should have 24 hr urine to document salt and K intake.CE Grim MD On Jul 25, 2012, at 12:17 PM, ww_engineer wrote: I'm a little confused by plasma renin measurememts and hope someone here cah help.

Guest guest Posted July 25, 2012 Report Share Posted July 25, 2012 Dr Grim: Thank you for response. The one hour time period now makes sense for an " acitvity " measurement. NIH sends the samples to the Mayo Clinic in MN for testing. The renin results come back first. I'll shave more data latet this week and will post.
