He had his blood tests so that he could have his yearly review. Apparently the result showed a low sodium . Not sure if this is relevant to the result but he was on his third course of antibiotics for a nasty chest infection. Had another blood test and this was better but they now want a third. Is this normal procedure? If its gone back to being low can anyone tell me what's likely to be advised. He is on daily Metformin.
Any advice would be great.
