Information for Washington State
Information taken liberaly from http://www.doh.wa.gov/ehsphl/phl/newborn/reports.htm
Our state mandates testing for:
Congenital Adrenal Hyperplasia
Maple Syrup Urine Disease (MSUD)
Medium-Chain Acyl co-A Dehydrogenase (MCAD) Deficiency
In 2000 (the last year there is published data), 77,575 infants were tested, and 260 were found to have a tested defect. Of those, only 2 were caught on the second screen instead of the first.
The test cost $35.50, which includes the first test, the second test, and any follow up tests to confirm the 'status of the infant'.
The state provides the most financial support to provide medial care for sufferers of PKU, but provides at least free education on all the tested items.
The state provides a breakdown of the cost to detect each item. It costs $102,000 to detect one case of PKU, as the rate is 1 in 13,174 tested infants. I guess we as a state have decided we consider it really important to prevent mental retardation as a result of PKU.
The most common finding was congenital hypothyroidism, with a rate of 1 in 3,634 tested infants (Cost: $33,980).
Total rate of occurance is 1 in 1,899 infants.
As far as I can tell, these are not suspected cases, where one or both parents has a family history, as those are sent to the lab as tubes of blood for more specific testing.
Also as far as I can tell, these are cases confirmed by later testing, these numbers do not include false positives.
