When a test is done too early, the results usually come out wrong. Ideally the test should be performed at least 48 hours after birth. If your child was tested too early than this is what happened. You have rights to your child's medical records. Do you live in the U.S.? If you do and your state has CAH screening that is mandatory, then the hospital better have screened for that!  I would like to know when the test was performed for my own research. I am so, so, surprised your child lived that long. How blessed you both are. Thank you for your input.
