An SSRI 44 Gene Comprehensive Panel looks at your DNA and your genetic makeup to see how your body reacts to certain medications. It specifically focuses on how you respond to SSRIs (Selective Serotonin Reuptake Inhibitors) which are commonly used to treat anxiety, depression, and other mood disorders to ensure you get the best treatment with the least side effects.
Our SSRI 44 Gene Panel, offered at all our clinics in London, is an advanced DNA test that analyses 44 genes influencing how your body processes SSRIs. This can help your healthcare provider develop a more personalised treatment plan tailored to your body’s unique needs.
When it comes to pharmaceuticals, one size does not fit all. Your genetics influence the way your body absorbs, processes, and eliminates medication. This means one person might benefit fully from an SSRI, while another might not.
Therefore, if you are currently taking or considering taking an SSRI, or have experienced side effects or a lack of effectiveness with SSRI medications in the past, you should get your genetic makeup screened.
In England, approximately 15% of the population received at least one prescription for antidepressant medications during the 2021/2022 period. That equates to about 8.7 million individuals. And around 10% of the UK population will experience depression at some point in their lives.
SSRIs are also among the most commonly prescribed. Therefore, knowing whether or not they will work for you right off the bat saves time, booking several unnecessary doctor’s appointments, and helps you feel better as you work towards improving your mental health.
The top reasons why you should opt for SSRI 44 Gene Testing include

Generally, there is no special preparation needed for this test. However, you may be asked to refrain from taking certain medications or supplements temporarily. Also, ensure your healthcare provider is aware of any SSRIs you are currently taking.
During your appointment, one of our healthcare professionals will collect a DNA sample from you. The panel will look at 44 genetic markers that influence how you metabolise SSRIs and other medications related to mental health treatment.
Once your results are ready, you will receive a comprehensive report detailing how your genetic profile may impact your response to SSRIs and other medications. Your doctor will go over the results with you, and offer guidance.
