abnormal pku test results

I dont want to be judged....

My son is 12 days old. We are in a different state, about 10 hours away from home, visiting family. We are leaving on Sunday or Monday to drive back home. It could be a year before we see our family again...

The pediatrician just called me today. She said my son's PKU results came back abnormal. And that he needs to be retested asap. I told her that we would be home by Tuesday and could do the testing then. I told her I could take him somewhere out here to have it done, but she said that Tuesday would be okay.

I've been worried, looking up everything I can about PKU.

does anyone have any sane and helpful advice, so I dont go crazy with worry?
