My son's OH17 was 85 and the ped endo said it was very good level. I was still worried so I called Cornell University and talked to a doctor that works with Dr. Maria New... and she said that it was very good level. It was very high at birth.. close to 2000. and had been 1000's. So you can see my concern!!! And the plasma renin was very high also. Which affects blood pressure. If it is off.... low blood pressure and shock.
