MyRx uses your genetic information to choose the medications and doses that are likely to work best for you.
Studies show 9 out of 10 people have variations in their genes that may change how they respond to common medications.
Pharmacogenetic testing looks at your DNA to see how your body might respond to certain medicines. Your doctor might suggest this test before you start a new medicine or if a medicine you are taking is not working well or is causing side effects. This test is only used for some medicines, mainly for treating common conditions such as:
Your results will tell us that certain medications:
Your privacy is important to us, and your test results will securely be stored in the UF Health medical record and MyRx patient portal. Results will only be shared with you and your doctor. Any remaining DNA sample will be destroyed by UF Health Pathology Laboratories. We do not sell or distribute your genetic information to third parties.
Pharmacogenetic testing is a way for doctors to learn how your genes affect your reaction to medicine. Genes are parts of DNA from your parents that give you special traits like height or eye color. They also play a role in whether a medicine will work well for you or cause side effects. With this testing, doctors can make better choices about which medicines and doses will help you the most.
The Genetic Information Non-Discrimination Act, or GINA, and the Affordable Care Act, or ACA, are two federal laws that prohibits insurance providers and employers from denying patients coverage or eligibility for health insurance or employment based on genetic results. GINA does not apply to the military, when an employer has fewer than 15 employees, or to disability, long-term care or life insurance benefits.

MyRx uses a simple swab to collect cheek cells containing a sample of your DNA. We will provide instructions on how to provide your sample.
If you need pharmacogenetic testing done, complete a simple, non-invasive cheek swab in just minutes (return envelope included) and provide your past and current medications.
If you already have pharmacogenetic testing done, upload your results and provide a list of current and past medications using our secure patient portal.
During your educational video consult, your pharmacogenetics specialist will review your results with you and answer any questions.
The pharmacist will provide a personalized medication plan for your doctor.
If you take a test before starting a new medicine, it can show if the medicine is likely to work well for you or if there is a risk of serious side effects. Tests taken before and during treatment can also help find the right dose.
After your visit, your doctor will receive a consultation note with personalized recommendations to match your DNA to the medication that works best for you. If you have any questions, please talk to your doctor about the results.
Tiny differences in your DNA can have a huge impact on your body and how it works. On the outside, your DNA determines how you look, like your eye color or your height. On the inside, DNA provides a recipe for all your organs and tissues, like your heart, lungs and muscles, even the smallest proteins or enzymes that your body makes. These proteins and enzymes determine how your body works.
Some proteins in the liver, such as those called the CYP450 enzymes, are very important in predicting how your body will respond to a medication. Tiny differences in your DNA can cause you to have too much, or too little, liver enzyme activity. This can result in a medication not working as well or a higher chance of side effects.
In most people, liver enzymes work just as we would expect, leading to a normal medication response. Based on genetic test results, we can more precisely determine how you respond to a medication and decide if you need a higher or lower dose or a different medication.
We will consult with your doctors if we have any recommended changes to your medications.
