My son failed his newborn screening and is having to have his blood tests repeated. He is a whole month old and I was just notifed! He goes for an appt on Tuesday to have his blood work redone. I am extremely upset because no one can tell me what it is he tested positive for and I won't know until the results from this coming up tuesday come back. All I have been told is that he failed the screening test and needs re-testing. I've read up on the diseases that it screens for and the thought of him having one is terrifying! The nurse did tell me that they can test positive at birth but after re-testing can be fine. Has anybody else had their little one fail the first newborn screening but pass the re-testing? I can do nothing but worry about my sweet little son now, he seems perfectly happy and healthy. He sleeps, eats, poops, rarely crys, he is the perfect baby. I am hoping and praying its nothing and he passes these new tests. Just wondering if anyone else has gone through this?
