I agree with Brea. I’ve never heard of some of the conditions that you mentioned and I know that some of them definitely aren’t because of untreated PKU. If she has black urine or a musky smell to her those are definitely signs of PKU. there are many diseases with similar symptoms so I wouldn’t get too agrivated over a different diagnosis. I would say get the test done to see if it’s PKU and if it comes back negative, there is nothing to worry about.
