Thanks Nickle730. Don't know what his levels were other than they were elevated. Obviously high enough to tell them to go to emergency straight away with him!

Had brief look on Google last night before I posted here and was frightened by what I read so though best to stear clear and come on here.

Will know more in next few days. Her DH gave update last night and looks like they he has a rare hormonal deficiency which is causing his kidneys to malfunction. However if it is this is can be treated with daily steroids for the rest of his life. Poor little mite. They're waiting for results to come back from Brisbane and will know more when they come back.

Thanks for the informative response x
