Genetic testing, also called genetic screening, is testing an individual's genetic background. It can be used to reveal details of individual's ancestry, or diagnose genetic diseases. It may also be used to determine whether a healthy individual is a carrier for a genetic condition.
Collecting a sample for genetic testing may involve collecting saliva or taking a blood sample. Genetic testing is carried out using different techniques from the field of molecular biology, such as DNA sequencing or karyotyping.
