Genetic testing is a type of medical test that determines changes in chromosomes, genes, or proteins.
Genetic test results can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or transmitting a genetic disorder.
There is currently more than 1,000 genes that can be tested and it is being developed more.
Several methods of genetic testing can be used:
Molecular genetic testing (or genetic testing).. study Individual genes or short lengths of DNA to identify differences or mutations that lead to a genetic disorder.
Genetic testing of chromosomes … full chromosomes or long lengths of DNA to see if there are significant genetic changes, such as an additional copy of the chromosome.
Biochemical genetic tests … that tell us the amount or level of activity of proteins, where anomalies in either of them can indicate changes in the DNA that lead to a genetic disorder.
Newborn screening … Newborn screening is used immediately after birth to identify genetic disorders that can be treated early in life.
Benefits and Candidates …
Genetic testing has potential benefits whether the results are positive or negative for a genetic mutation.
Test results can provide a sense of relief from uncertainty and help people to make definitive decisions about managing their health care. For example, a negative score can eliminate the need for unnecessary checks and exams in some cases.
A positive outcome can direct a person towards the available prevention, monitoring and treatment options.
Some test results can help people make decisions about having children.
Neonatal screening can identify genetic disorders early in life so that treatment can start as soon as possible.
Possible complications …
The physical risks associated with most genetic tests are very small, especially those that require only a blood sample or biopsy a method that takes samples of cells from the inner surface.
Procedures used in prenatal testing carry a small but real risk of pregnancy loss (miscarriage) as they require a sample of amniotic fluid or tissue from all parts of the fetus.
Many risks associated with genetic testing involve the emotional, social, or financial consequences of the test results.
Genetic testing can provide only limited information about an inherited condition.
The test often cannot determine whether a person will exhibit symptoms of the disorder, the severity of the symptoms, or whether the disorder will progress over time.
From preparing for the test to the results …
Before the test …
Before a person undergoes a genetic test, it is important to understand the test procedure, the benefits and limitations of the test, and the possible consequences of the test results.
Once a person decides to proceed with a genetic test, a medical geneticist, primary care physician, specialist or nursing nurse can take the test.
Genetic testing is often done as part of genetic counseling.
2 – During the test :
Genetic testing is done on a sample of blood, hair, skin, amniotic fluid (amniotic fluid during pregnancy) or other tissues.
For example, a specific procedure uses a small brush or a cotton swab to collect a sample of cells from the inner surface of the cheek. The sample is sent to the laboratory where technicians search for specific changes in chromosomes, DNA, or proteins, depending on the suspected disorder.
The laboratory communicates the results of the test in writing to the person’s physician or genetic counselor, or directly to the patient if requested.
Newborn screening tests are done on a small blood sample, which is performed by pricking the baby’s heel.
Unlike other types of genetic testing, a parent will only receive the result if it is positive.
If the test result is positive, an additional test is required to determine if the child has a genetic disorder.
3 – Results :
The results of genetic testing are not always straightforward, which makes them difficult to interpret and interpret. Therefore, it is important for patients and their families to ask questions about the possible meaning of genetic test results before and after the test.
When interpreting test results, healthcare professionals consider the person’s medical history, family history, and the type of genetic test that was performed.
A positive test result means that the laboratory has found a change in a specific gene, chromosome, or important protein.
Depending on the purpose of the test, this result may confirm the diagnosis, indicate that a person is a carrier of a particular genetic mutation, or specifies an increased risk of developing a disease (such as cancer) in the future, or indicates the need for further testing.
Because family members have some common genetic material, positive test results may have effects on some of the blood relatives of the person being tested.
A negative test result can mean that the test has missed a genetic change that causes the disease because many tests cannot detect all the genetic changes that can cause a particular disorder. Further testing may be required to confirm a negative result.
In some cases, the test result may not give any useful information. This type of outcome is called non-informative, non-specific, inconclusive or vague.
The results of non-informational tests happen sometimes because everyone has common natural differences in DNA, called polymorphism, that do not affect health.
