Screening, newborn hearing
- inherited). Which screening tests should be done is decided in the U.S. on a state-by-state basis. The most common screening tests now include those for hypothyroidism (underactivity of the thyroid gland), PKU (phenylketonuria), galactosemia, and sickle cell disease. The addition of a hearing test to the battery of newborn screening now appears to make medical and economic sense. As of 1999, only a handful of states in the U.S. mandated newborn hearing screening and only about 15% of all newborns were tested for their hearing in the hospital where they were born. The overall rate of hearing loss found in one study in the U.S. was about 1 in 330 newborns. The frequency of congenital hearing loss (hearing loss at birth) was 260 per 100,000 births. This is a much higher incidence than for other conditions that are routinely screened in newborns.
