All you need to know about pathology testing

Pathology tests are essential to modern medicine. They provide the information needed to make diagnoses, screen for illnesses and monitor treatment and medication. We’re here to help you understand them with up-to-date information written by practising Australian pathologists and senior laboratory scientists.

Last month’s news article was about genetic testing to detect increased risk of developing cancer. This month we will look at three advances in genetic testing in patients who already have cancer diagnosed.

A large international effort by more than 1,000 scientists has revealed scores of genetic markers that can identify people most likely to develop the diseases. In the future a relatively cheap test using saliva which contains cells and thus DNA could be used to identify individuals who are at higher than average risk for developing these diseases.

A non-invasive maternal blood test that can detect certain fetal chromosomal disorders, including Down syndrome, early in pregnancy is gaining attention as a potential new method of prenatal screening.
