Genetic testing

Several types of genetic testing are done for different reasons: Diagnostic testing. If you have symptoms of a disease that may be caused by genetic alterations, genetic testing can reveal if you have the suspected disorder. Examples of disorders for which genetic testing may be used to confirm a diagnosis include adult polycystic kidney disease, iron overload (hemochromatosis) and Charcot-Marie-Tooth disease. Presymptomatic testing. If you have a family history of a genetic condition, undergoing genetic testing before you have symptoms may show if you're at risk of developing that condition. Carrier testing. If you or your partner has a family history of a genetic disorder, such as sickle cell anemia or cystic fibrosis, you may choose to have genetic testing before you have children. Genetic testing can determine if you carry a copy of an altered gene that would put a child at risk of developing the disorder. Prenatal testing. If you are pregnant, tests are available that can detect abnormalities in your fetus's genes. Spina bifida and Down syndrome are two genetic disorders that health care providers often screen for using prenatal genetic testing. Newborn screening. This is the most common type of genetic testing. In many states, it's required that all newborns be tested for gene abnormalities that cause specific conditions, such as congenital hypothyroidism and phenylketonuria. This type of genetic testing is important because if a disorder is found, care and treatment can begin right away.

Home Pregnancy Test
If you think you are pregnant, you may want to test yourself at home with a home pregnancy test. You can buy test kits at a drug store without a prescription. Home use kits measure a hormone called human chorionic gonadotropin (hCG) in your urine. However, these tests are qualitative, the results are either positive or negative for pregnancy. The most sensitive test of pregnancy is best performed by a laboratory using a sample of your blood. These tests not only detect hCG but also can indicate the amount (quantitative tests) of the hormone, which doubles every 2-3 days during the first several weeks of pregnancy. These more sensitive tests can tell how long you have been pregnant and even detect possible problems with the pregnancy. Your health care provider can perform this test.

Hearing and vision tests for children
Babies can respond to sights and sounds from an early age. Midwives and hospital staff carry out a number of tests on every newborn baby. These tests help find any problems that a child is born with. These include genetic (inherited) conditions, such as being born with cataracts, or the results of any infections caught by the mother during pregnancy. For example, there is a small risk that a woman who catches rubella during pregnancy might have a child with a hearing impairment. In 2000 the government announced that every newborn baby in England would have a hearing test during the newborn period. This was implemented by March 2006.
