Potassium level decreased during Saline Suppression Test

[Guest guest]

Hi everyone,

I posted a couple weeks ago, that my Saline Suppression test was inconclusive

because I was on Amlodipine and Atenenol, also my K taken at the beginning of

the test was 3.1 (should be 3.5). So, my Endo switched me to Varapamil for the

past 2 weeks and we re-did my test. This time my K was 3.6 prior to test. At

the end of the test it was down to 3.1. The results of the test take a week or

so. Does anyone know if it is normal for potassium to fall this drastically

during the test (last time it didn't drop much at all). Would the low K level

ruin the results again?

, age 39.75 2cm adenoma on left adrenal gland, ARR over 200. I am on

180m Verapamil Slow Release, 7 potassium pills daily (20 meqs) and my K never

gets higher than about 3.8, BP is creeping back up again, was doing fine on

Amlodopine and Atenenol.
