Genetic testings are recent breakthroughs in medicine that have proven useful in identifying illnesses and defects. Genetic testing process is simple in that it looks for changes in DNA that might be an indicator of defects or disorders.
Genetic testing will give the physician a better idea of how to treat patients. You will find many genetic testing services in Bloomington up to the task. Sometimes, some matters are delicate and might require you to perform your genetic testing in Martinville.
What is genetic testing?
Genetic testing is a test that detects changes in our chromosome or DNA which helps provide diagnosis and hence, better care. A genetic test is carried out using blood, spit, or hair and the results are analysed.
Genetic testing is carried out to detect changes in
Gene
Different DNA sequences make up the body. The test detects mutations in genes that can cause the disorder. Gene tests can be broader or narrow depending on what you are looking for. You can analyse one or more genes or a person’s DNA
Chromosome
chromosomal testing detects changes in the chromosome or longer DNA length. Changes to be detected include a larger copy or extra copy of chromosomal materials that can lead to defects.
Proteins
This test studies biochemical changes and activity level of enzymes
Uses of genetic testing
Genetic testing provides background information about a person’s gene; some of the uses of gene testing include:
Carrier testing
Carrier testing helps determine whether an individual is carrier of some genetic defects. When gene mutation is present in two copies, then it is a disorder. This type of testing offers physicians a glimpse into their genetic background.
It makes it easy to deduce a genetic disorder, especially if it is prevalent in some family background or ethnic group.
Newborn screening
Genetic testing is performed on newborns to screen them for genetic defects or disorders. If a disorder or defect is detected, the parent will be prepared and know ways to follow to manage the condition.
Prenatal screening
Prenatal screening helps detect whether there is a mutated gene in a foetus. This is carried out when an individual has a family history of certain defects. In any case, it reduces uncertainty and helps couples make a decision about a pregnancy.
Diagnostic testing
Genetic testing in Diagnostic is used to confirm a person’s diagnosis when a particular genetic defect is suspected. It identifies whether an individual will express a particular gene defect. Sometimes, it is carried out in infants or during pregnancy
Forensic testing
In Forensic testing, DNA is used to identify an individual for legal purposes. Here genetic testing isn’t to detect genetic disorders but to identify an individual or establish relationships, e.g. paternity
Genetic testing results
Genetic testing can either be positive or negative. The positive scenario identifies or detects mutations in an individual’s gene. In a Forensic case, it successfully establishes a blood relationship or validates the presence of a suspect. While a negative scenario is when mutated genes are not present in a person’s DNA
