Earlier, the definitions and points to consider in carrying out different types of Genetic Testing were discussed. Genetic test has been helping individuals who are unaware or suspicious that they may be a carrier of genetic condition or at risk of developing such condition.
Through a thorough analysis and evaluation of one's DNA, RNA, proteins, chromosomes and some metabolites, genetics professional can determine whether an individual has the gene mutation.
There are six different types of Gene test and their function or purpose is indicative of the nature of such test. These tests are Diagnostic, Predictive, Carrier, Pre-natal, Pre-implantation and Newborn.
The Genetic tests left for discussion are the Pre-implantation and the Newborn. As the name of the test suggests, the Pre-implantation testing is given on early embryos which are a result of In Vitro Fertilization in pursuit of reducing the chances of having the genetic condition to affect or occur in the fetus.
Generally though, the Pre-implantation Genetic testing is recommended to couples who have high chances of passing onto the unborn fetus a serious illness. This type of Gene test is an alternative to Pre-natal test and termination of afflicted conception.
Maybe because of its limited applications, only a few Genetics centers perform the Pre-implantation test, and it is only available for a limited number of illnesses.
Moreover, the Pre-implantation Diagnostic test is simply impossible in some instances since the it is difficult to obtain eggs or early embryos and challenges in the procedure of DNA analysis. As the chances of having errors on the test are quite remarkable, the conventional Pre-natal diagnostic approaches are advised to monitor the pregnancy. Unlike the Diagnostic test, the cost for Pre-implantation test is very high and not covered by insurance.
The primary objective of Newborn Genetic test is to identify the individuals who are at higher chances of developing a certain genetic illness so that proper treatment can begin the soonest possible. As it is not designed to diagnose a disease, the Newborn Screening may identify individuals who should be performed with further diagnostic tests.
The Newborn Screening programs usually vary from state to state, nevertheless, they are generally mandated by law. Such screening programs are initiated by routine at birth, unless the parents explicitly refuse the test by writing.
However, in most cases, parents are unaware that their newly born infants have been performed with Newborn Screening tests or which tests were included in the programs, even if they have already signed a waiver or consent form when the child was given to birth. In order to avoid misunderstandings, discrimination and anxiety, it is best to have education about the disorder should the test proved positive.
The Genetic testing can be ordered by a genetic counselor or medical geneticist as part of a genetic consultation. It can also be ordered by a specialty or primary care provider. In choosing which test is appropriate, one should consider the laboratory, the nature and requisite of pre-test counseling and informed consent, the availability of sample logistics and supporting documentation, and the interpretation of test result and possibly, follow-up appointments.
