Invasive diagnostics
Invasive diagnostics is a medical diagnostic procedure that requires an intervention in the body of the person being examined. However, blood draws do not count towards invasive diagnostics.
Where possible, non-invasive testing is preferred, as invasive testing carries an increased risk of adverse effects.
Invasive diagnostic methods of medicine in general are:
- the angiography
- the cardiac catheterization
- the endoscopy
Invasive methods of prenatal diagnosis are:
Invasive examination methods are associated with different levels of risk of miscarriage and are usually carried out when the calculated probability that the unborn child has a disease, disability or malformation that can be identified by the examination is higher than the risk of a miscarriage.
In many cases, before deciding for or against an invasive procedure, the options of non-invasive examinations, such as fine ultrasound or neck transparency measurement , are used. With regard to chromosomal peculiarities, however, no diagnoses are possible using ultrasound. Only physical signs can possibly be recognized, which means that "the ultrasound examination [...] also becomes the splint for prenatal-invasive measures such as amniotic fluid puncture , chorionic villus sampling and chordocentesis ."
