Why are babies tested?

• Our tests could save your baby's life.
  
• We test all Arizona babies and help those who have certain rare, inherited diseases or hearing loss.
  
• Most babies are healthy when they are born.  A few babies look healthy but have a rare health problem.
  
• If the problem is found early, we can help prevent serious results like mental retardation or death.
  
• Correcting hearing loss will help your child learn speech and language.  About three in every one thousand babies have some degree of hearing loss.

When are babies tested?

• Before they leave the hospital, a nurse will take a few drops of blood from your baby's heel.  The hospital will also do the hearing test.
  
• The hospital will send the blood sample to the newborn screening lab.
  
• Arizona collects two blood samples to ensure no disorders are missed.
  
• Call your baby's doctor about the second blood sample.
