Genetic testing involves examining your DNA. Genetic testing is a medical procedure that uses DNA to identify changes. These tests can help confirm or rule out suspected genetic conditions, as well as provide information about a person’s chance of developing or passing on a genetic disorder. Know about your ancestry DNA and see how it shapes your cultural, political, or political significance through the use of our advanced DNA testing technology. With accurate ancestry DNA testing stay rest assured about your results through the use of our services. Over 77,000 such tests are currently in use, and new ones are being developed constantly.
To understand how DNA test is performed, you need to know that genetic testing involves looking for changes in the following:
- Genes: Gene tests analyze variations (mutations) in a person’s genes in an effort to identify those that may increase the risk of developing a genetic disorder. There are two types of gene tests: narrow scope, which examines one or more genes, and large-scope testing, which looks at all of a person’s DNA.
- Chromosomes: Chromosomal genetic tests look for large-scale changes in a person’s DNA, such as an extra copy of a chromosome. Chromosomal genetic tests help one know about abnormalities that may lead to conditions like Down Syndrome or cancer.
- Proteins: Biochemical genetic tests involve measuring the level or activity of proteins or enzymes. Abnormalities in either of these can signal changes to a person’s DNA, which may lead to a genetic disorder.
Why Is Genetic Testing Useful?
Genetic testing is essential for understanding the risk of developing certain diseases, as well as screening potential medical interventions. From finding out about your ancestry DNA to taking certain precautions for your health, there can be a lot of reasons for which you can undergo genetic testing. There are a variety of types of genetic tests that can be carried out for different reasons, such as the following:
- Diagnostic Testing: By studying mutated genes, genetic testing can be used to determine if an individual has a disorder that is likely caused by genetic changes. For example, this could include confirming the diagnosis of cystic fibrosis or Huntington’s disease.
- Presymptomatic and Predictive Testing: Presymptomatic and predictive testing refers to the practice of identifying risk factors for a particular condition prior to actually experiencing symptoms. This type of test can be helpful in determining whether you are at risk for developing a certain condition, such as colorectal cancer. Presymptomatic and predictive testing can especially be very useful if you have a family history of a genetic disorder or condition.
- Carrier Testing: This type of genetic testing can be very useful before having children. If there is a genetic disorder in the family history, Carrier testing is a procedure used to determine if you are carrying the gene and if there is the possibility of you passing it on to your offspring.
- Pharmacogenetics: Pharmacogenetics is the study of how a person’s genetic makeup can affect their response to medications. If you are diagnosed with a particular health condition, pharmacogenetic testing may help determine which medication and dosage will be most effective for you.
- Prenatal Testing: During pregnancy, tests can detect certain genetic abnormalities in the baby. Down syndrome and trisomy 18 syndrome are two genetic disorders commonly screened for with prenatal genetic testing. Traditionally, this has been done using markers in the blood or by invasive tests such as amniocentesis. A new test, called a cell-free DNA test, looks at the baby’s DNA through a mother’s blood test.
- Newborn Screening: As a part of this test, newborns are screened for certain genetic and metabolic abnormalities that cause certain medical conditions. This type of genetic testing allows immediate initiation of care and treatment if results indicate the presence of disorders such as congenital hypothyroidism, sickle cell anemia, or phenylketonuria (PKU).
- Preimplantation Testing: Also called preimplantation genetic testing, this test can be used if you are trying to conceive a child through in vitro fertilization. This type of genetic testing examines embryos for genetic abnormalities.
How Can You Prepare For Genetic Testing?
Knowing and understanding how DNA tests work or how DNA is performed is one of the first steps in preparing for genetic testing. The next step is to gather as much information as possible about your family’s medical history before undergoing genetic testing. You can talk to your doctor or genetic counselor about your personal and family medical history to better understand your risks. In the interaction with the doctor, you can ask questions and discuss any concerns you may have about how DNA tests are performed or if you have any doubts about how DNA tests work.
You should discuss the decision to have genetic testing with your family. By having these conversations before genetic testing, you can learn about how your family will react to your test results and how it will affect them.
Not all health insurance companies cover the cost of genetic testing. Therefore, check with your insurance company what costs will be covered before getting a genetic test done.
How Is DNA Test Performed?
Depending on the type of genetic test, a sample of blood, skin, amniotic fluid, or other tissue is taken and sent to a laboratory for analysis. Here are the different ways how DNA test is performed:
- Collection Of Blood Sample: A member of the medical team will insert a needle into a vein in your arm to take a blood sample. Newborn screening involves taking a blood sample by pricking the baby’s heel.
- Cheek Swab: For some tests, a swab is taken from the inside of the cheek for genetic testing.
- Amniocentesis: For this prenatal genetic test, a doctor inserts a thin, hollow needle through the abdomen into the uterus and removes a small amount of amniotic fluid for testing.
- Chorionic Villus Biopsy: For this prenatal genetic test, a doctor takes a tissue sample from the placenta. Depending on the situation, a tube (catheter) is used to take a sample from the cervix, or a fine needle is used to take a sample from the abdomen and uterus.
Now that you are familiar with the different ways how a DNA test gets performed, you can choose a method that bests suits you as an individual.
