Testing that is done with the purpose of determining if the person being tested carries a specific gene, such as one that can cause a specific disease.
Methods that identify the presence, absence or mutation of a particular gene in an individual.
The examination of a person's DNA for biochemical, chromosomal, or genetic markers that indicate the presence or absence of genetic disease.
examining a sample of blood or other body fluid or tissue for biochemical, chromosomal, or genetic markers that indicate the presence or absence of genetic disease.
Testing of a person's genetic material for abnormalities, defects and deficiencies, including carrier status (the possibility that a health person carries particular genes that may affect his/her descendants)
Testing a sample of blood (or another fluid or tissue) for evidence of a gene. The evidence can be biochemical, chromosomal, or genetic. The aim is to learn whether a gene for a disease is present or absent.
