What is the biggest ethical dilemma concerning genetic testing?
In a large number of instances, when patients receive the results of genetic tests, they are party to information that directly concerns their biologic relatives as well. This familial quality of genetic information raises ethical quandaries for physicians, particularly related to their duty of confidentiality.
What are the ethical arguments for and against DNA screening?

How reliable is genetic testing in predicting diseases?
Challenges of predicting genetic risk A major impediment of a genetic risk prediction test for common diseases is that it can’t be used as a diagnostic instrument because it has low accuracy. Existing tests for rare genetic diseases are straightforward and accurate because they test for a faulty copy of a single gene.
What is the most reliable test in detecting genetic abnormalities?
Chorionic Villus Sampling (CVS)
How can you tell if your fetus is abnormal?
Screening Tests
- First Trimester Screening. First trimester screening is a combination of tests completed between weeks 11 and 13 of pregnancy.
- Second Trimester Screening.
- High resolution Ultrasound.
- Chorionic Villus Sampling (CVS)
- Amniocentesis.
How can genetic abnormalities be detected?
Most of the time, genetic disorders are diagnosed through a specific test, which can include examining chromosomes or DNA (the tiny proteins that make up genes), or testing the blood for certain enzymes that may be abnormal.
When would someone use genetic screening?
You may want to consider genetic testing if:
- you or your partner is at risk of passing on a genetic condition (like cystic fibrosis)
- you or your partner has a chromosome condition, or has a child with a chromosome condition (like Down syndrome)
Is blood or saliva better for genetic testing?
Yielding virtually the same amount of DNA per volume and the same DNA quality as blood, saliva can be considered equivalent to blood for genetic applications.
What do genetic blood tests show?
Genetic testing – sometimes called genomic testing – finds changes in genes that can cause health problems. It’s mainly used to diagnose rare and inherited health conditions and some cancers.
What does a positive genetic test mean?
