This quality assurance includes laboratory accreditation, director certification, and proficiency testing. Surveys have been done on many research laboratories and have reported that some don t make the grade. The type of molecular genetic testing that is generating the most intense interest involves those associated with disease. This type of testing has the potential to reduce the impact of genetic diseases on the human race. Prenatal screening is exactly what it sounds like.
Scientists test the fetus to detect various genetic disorders at early stages.
This can provide parents with critical information about their pregnancies. Today, aside from gender, the only traits that can be identified at the earliest stages of development are about a dozen of the most serious genetic diseases. A few of these disease are gender related, so a beneficial way to reduce the risks of being susceptible to a certain disease is to choose the most advantageous gender for that child. As it so happens, the Y chromosomes have slightly more DNA than X chromosomes. As well as prenatal screening, newborn screening is used to detect genetic disorders at an early stage.
