he got called back into harefield this morning as onew of the blood tests revealed his sodium level last night was a little on the low side (21). had another test done today and it has come back ok (25, so u can see how close the numbers are). they will repeat it tomorrow just to make sure. but the doc who called him in has been told there was no need to re-admit dh. so he is away from home when he doesnt need to be.
