What is a Genetic Testing Lab?

Genetic testing uses DNA extract for identifying any genetic health problems, prenatal testing and newborn screening. Genetic testing is conducted by accredited laboratories that have legal permission to conduct these tests. The information secured is kept private and confidential, and the information is not leaked to third parties with a vested interest in the evidence.

Basically, there are 5 types of Genetic testing:

-       US healthcare centers conduct newborn screening to check any dangerous health conditions like congenital hyperthyroidism.
-       Expectant mothers usually obtain prenatal testing to screen the fetus for bearing any disease symptoms such as Down Syndrome, physical deterioration, or mental retardation.
-       Families obtain genetic testing to know about the prevalence of recessive genetic disorders such as sickle cell disease or cystic fibrosis.
-       Genetic tests identify the late onset of diseases like Huntington’s or various types of cancer. The tests identify the possibility of predisposition of these health problems. 
-       To identify individuals on the basis of DNA fingerprinting. Forensic sciences use DNA evidence to convict or exonerate criminals.

Genetic testing labs conduct genetic tests follow ethical considerations and adhere to the guidelines provided by healthcare authorities. Costs of testing varies with genetic testing labs but are usually quite expensive tests and require a few days for the results to become available.
