I am so happy to read that Cooper is holding his own! I am very relieved to see there has been no more diarrhea, hopefully that means things are turning around.
Marianne, you are exactly right about the Percorten. It is a mineralocorticoid replacement only and would not affect the cortisol readings. It does not have glucocorticoid properties, which is why prednisone (or another glucocorticoid) is given for cortisol replacement if necessary. Percorten is given to regulate sodium absorption and potassium excretion when aldosterone is over suppressed. If both cortisol and aldosterone are over suppressed, then both replacement hormones are needed.
I have to work in the morning, but will be checking in for an update on Cooper tomorrow. I hope you all have a quiet night and are able to get some sleep.
