Pharmacogenetic tests are a type of genetic test that can provide important information about how your genes affect the way you respond to certain medications. With pharmacogenetic tests, a small sample of your DNA is collected, usually by swabbing the inside of your cheek or taking a blood sample. These tests can help doctors determine which medicines are most likely to work for you and which may have serious side effects.
Pharmacogenomics, a branch of pharmacology, focuses on how genes affect a person’s response to medications. The goal of pharmacogenetic testing is to identify genetic variations that may affect how your body processes and responds to medications. By identifying these variations, doctors can choose the most effective medications and avoid those that may not work or could have serious side effects.
During pharmacogenetic testing, a small tube or needle is used to collect a sample of your genetic material. This sample is then sent to a laboratory where it is analyzed for specific genetic variations. The results of the test can provide important information about how your genes may affect your response to certain medications.
There are many reasons why someone may opt to have a pharmacogenetic test. For example, if you have a family history of a particular condition, such as heart disease or cancer, a pharmacogenetic test may help determine if you are at increased risk for developing the condition and if certain medications may be more effective in treating or preventing it. Additionally, pharmacogenetic tests can be useful for individuals who have tried multiple medications without success or have experienced serious side effects.
What is it used for
Pharmacogenetic tests are used to determine how a person’s genes can affect their body’s response to certain medicines. These tests involve collecting a sample, usually a swab of the inside of the cheek or a blood sample. Unlike other types of genetic testing, pharmacogenetic tests focus on specific genes that are known to affect how the body processes and reacts to medications.
The main reason for having a pharmacogenetic test is to help healthcare providers choose the right medication and dose for an individual patient. By identifying specific genetic variations that may alter the way a drug is metabolized, doctors can predict a patient’s likely response to a medication. This can be especially important for drugs with a narrow therapeutic index or serious side effects.
As of August 2020, the most expensive drug in America is Myalept, a drug used to treat leptin deficiency. A month’s worse of this drug costs $71, 306 per month, according to research from GoodRx. Myalept is known as an “orphan drug” because it’s intended to treat a rare disease.
The testing process typically takes a few minutes. For a cheek swab test, a small brush is used to collect cells from inside the cheek. For a blood test, a healthcare provider will typically use a needle to draw blood, which is then sent to a lab for analysis. Once the sample is collected, it is sent to a laboratory where specialized genetic testing techniques are used to detect any genetic changes that may influence how a person responds to certain medications.
