|contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!|

There are a number of different neonatal screening (newborn screening) programs in different countries testing for various "common" congenital abnormalities and infections. Perinatally the infant is tested physically for hip displasia and may have an x-ray to establish the extent of musculoskeletal abnormality. There are also a number of other systems (renal, cardiovascular, respiratory, gastrointestinal, endocrine and genital) that can be assessed postnatally by x-ray alone or in combination with tracers or contrast agents.
Radiation is a known teratogen and can affect development, but there is ongoing discussion as to the associated fetal risk and that to maternal health of a range of conditions that are detected or analysed using x-radiation.
- Prenatal diagnosis - number of different techniques (non-invasive, invasive) for determining normal development
- Neonatal diagnosis (APGAR test, Guthrie test, Hearing test)
- Maternal diagnosis - often pregnancy will expose maternal health problems

Gastrointestinal Tract Abnormalities
A new site developed by NIH "GeneTests" provides medical genetics information resources available at no cost to all interested persons. It contains educational information, a directory of genetic testing laboratories and links to other databases such as OMIM.
