Genetic Testing

The term genetic testing is used to describe tests that reveal information about a person’s genetic makeup. Sometimes the genes themselves are tested to determine the presence or absence of a change in gene structure. For example, in some cystic fibrosis screening programmes the baby’s genes are tested. Sometimes tests aren’t actually carried out on the genes but will reveal genetic information. In haemoglobin-opathy screening, blood tests can indicate that someone is a carrier of a sickle gene (even though the gene itself is not examined).
