Genetic tests are used to observe or determine genetic disorders a person may possess. It involves examination of the DNA molecule. Genetic tests can be performed through biochemical experimentation of genetic materials. The medical specialists can observe the person’s enzymes and other protein parts. Through the help of genetic tests, genetic disorders may be diagnosed. Inherited diseases may also observed to know from what ancestry (maternal or paternal side) did it came from. Genetic tests provide one the information of gene mutations which may be associated with genetic disorders. Once certain observations are made, a person having a genetic disorder may be recommended for genetic counselling.
Here are some genetic tests available nowadays. These tests involve the analysis and observation of DNA. One should be thankful that these tests are already in reach because the information provided in these tests, certain conditions may already be known even after birth.
Prenatal testing – This test detects the changes which may be found in the genes and chromosomes of a fetus. With this, parents who are known to have a large risk of having babies with genetic disorders can immediately know the uncertainty of their child’s normality. This can also help them to be ready with the treatment that their child must have once born.
Newborn testing – This screening type allows one to know the genetic disorders that may be present in the newly delivered child. With this, the parents of a newly born child may gain knowledge of the diseases their child possesses. After this, further observations can be made. Diagnosis may also help in early treatment.
Carrier testing – This test involves identifying a person who might carry a copy of a gene mutation. This gene mutation which causes two copies of a certain chromosome lets one incur a genetic disorder. The test can be done to individuals who suspect having a certain genetic disorder already present in their family for a long time already. Also, testing both parents and knowing the results may help them know the probability of what genetic disorder their child may inherit.
Parental Testing – This test aims to observe the special marking found in one’s DNA to know the similarity of one to the other. These patterns are commonly inherited from parent to child. Finding a similar pattern may be provided as a basis of parental lineage. Matching DNA sequences can provide the conclusion of blood relatedness. This is normally done by people who are unsure of their family heritage. The Genetic Paternity Test is an example of a parental test.
Forensic Testing – This test is done to observe the DNA sequences of a person for criminal investigation. This test is different from other genetic testing because its aim is not t know the genetic disorder a person possesses. The results are used for legal purposes. This test is normally used to identify what happened to crime victims. Also, it can establish the norm of knowing the suspect of a certain law violation. In this way, the use of science will be utilized in solving crimes that bugs the nation.
