Before knowing whether we should or should not perform genetic testing, we should get the general knowledge of what genetic testing really is. Genetic testing can be described as a medical test that is performed in our bodies to identify any change in the genes and other elements that compose the body system. This medical test has an added advantage even if the outcome is negative because it helps in planning and decision making concerning our health.
METHODS USED FOR GENETIC TESTING
Some of the genetic tests that are in use include;
1. Gene tests– These help in analyzing single genes and hence the variations that can lead to genetic disorders are identified.
2. Chromosomal tests– These help in studying chromosomes do identify the huge genetic changes.
3. Biochemical tests– These tests analyze the quantity of proteins to identify any genetic disorder.
BENEFITS OF GENETIC TESTING
Genetic testing has its advantages, some of them include;
1. It helps with information that helps in planning for children in future.
When you are at the edge of giving birth to a child with a genetic condition, genetic testing gives the possibility of performing a test to determine whether the unborn child is affected so that treatment can start as early as possible. It also gives mental preparedness when you are aware that you are at a huge risk of bearing a child with a genetic disorder.
2. PROVIDES IMPORTANT GENETIC INFORMATION TO CLOSE FAMILY MEMBERS
Genetic conditions are often similar for close family members; hence your genetic composition information is useful to them in either planning for children or to avoid wrong diagnosis.
3. GENETIC TESTING HELPS IN DIAGNOSIS OF GENETIC CONDITION
Genetic testing can indicate complications in future life hence regular check up minimizes the possibility of such complication. Keen diagnosis is always followed by proper treatment.
4. Genetic testing can get to get some of the experimental treatments that are given to patients with positive tests.
5. It also qualifies some patients for screening.
6. Scientists or rather experts have also come up with medicine due to genetic testing.
LIMITATIONS OF GENETIC TESTING
Every process with benefits also has its limitations and therefore genetic testing also has its risks. They include;
1. A confirmation of a possible diagnosis from a genetic test doesn’t necessarily imply that treatment is obviously available.
2. The waiting period for results usually causes panic.
3. If there is a risk of a genetic disorder, this can cause mixed feelings in your family members due to the risk of passing genes down the family line.
4. Genetic testing could also reveal the secrets within a family especially for the adopted members.
5. Even if a genetic test is performed, in some the possibility of determining the extent to which they will be affected is not easy.
Every decision we make is crucial. Genetic testing is very important in one’s life though it also has its limitations. Therefore, making a decision to go for it requires lots of consultation from professionals or medical practitioners.
