Genetics-Informed Psychiatry
Use your DNA to find the right psychiatric medication — faster, safer, with fewer side effects.
Understanding How Your DNA Affects Treatment Response
Why does one antidepressant work miracles for one patient and cause severe side effects in another? A big part of the answer is genetic. Specific genes — particularly the cytochrome P450 family — control how your body metabolizes most psychiatric medications. Variations in these genes mean that the same dose of the same medication can produce drastically different results.
Pharmacogenetic testing reads these genes from a simple cheek swab or blood sample. The results tell us which medications are likely to work well for you, which are likely to cause side effects, and which dosages will be most effective — before prescribing.
At MetroMind, pharmacogenetic testing is integrated into our precision psychiatry workflow. When medication is being considered, we use genetic data to shortlist the medications most likely to work for your specific biology — reducing the months that traditional trial-and-error often costs.
When Testing is Most Valuable
Multiple failed medication trials
If two or more antidepressants or anxiety medications haven't worked, your metabolism may be the reason. Testing often reveals why.
Severe medication side effects
Some patients experience disproportionate side effects to standard doses — often because they are poor metabolizers.
Starting medication for the first time
Testing before the first prescription can shortcut the trial period and reduce the risk of trying a medication your body can't process well.
Family history of medication intolerance
Metabolism variations are heritable — if family members had bad reactions, you may share the same genetic patterns.
Complex cases with multiple medications
Testing helps predict drug-drug interactions and informs combination prescribing to manage side effects.
What Pharmacogenetic Panels Measure
We analyze variations in several key genes affecting psychiatric medication response.
CYP2D6
Metabolizes many antidepressants (paroxetine, fluoxetine, venlafaxine) and antipsychotics. Variations classify patients as poor, intermediate, normal, or ultra-rapid metabolizers.
CYP2C19
Metabolizes SSRIs like sertraline, citalopram, and escitalopram. Poor metabolizers have higher side effect risks; ultra-rapid metabolizers may need higher doses.
CYP2C9, CYP3A4, CYP1A2
Additional metabolizing enzymes that affect specific medications used in bipolar disorder, anxiety, and ADHD treatment.
SLC6A4 (serotonin transporter)
Variations affect SSRI response specifically. Certain variants predict better or worse response to serotonin-based medications.
HLA variants
Some genetic variants predict severe allergic reactions to specific mood stabilizers (e.g. carbamazepine). Testing prevents potentially dangerous prescriptions.
How Genetic Testing Works
A simple, one-time test that informs medication selections for life.
Clinical Consultation
Your psychiatrist reviews your case to determine whether genetic testing is clinically indicated based on history.
Sample Collection
A simple cheek swab or blood sample, done in our facility. No fasting required.
Laboratory Analysis
Sample is processed at a certified pharmacogenetic laboratory. Results typically return within 7–14 days.
Clinical Interpretation
Your psychiatrist reviews the report and integrates the findings into your treatment plan, categorizing medications by safety.
Lifetime Utility
Your genetic profile does not change. The same report can guide medication decisions for years.
Why Choose MetroMind for DNA testing
Clinical interpretation
Many labs return raw reports. Our psychiatrists translate genetic data into specific clinical recommendations for your case.
Integrated with overall care
Genetic data is one input into a precision treatment plan — combined with clinical assessment and qEEG data.
Evidence-based prescribing
We use established CPIC guidelines — not vendor marketing claims — to translate genes into prescriptions.
One-time, lifetime value
A single test informs medication decisions for years across multiple conditions, not just psychiatric ones.
Frequently Asked Questions
Will pharmacogenetic testing tell me exactly which medication to take?
Not exactly. Genetic testing tells us which medications are more or less likely to work for your specific metabolism, and which are more likely to cause side effects. The final medication choice is made by your psychiatrist by combining genetic data with clinical factors.
Is pharmacogenetic testing covered by Indian insurance?
Coverage varies by insurer and policy. Most psychiatric pharmacogenetic tests are currently paid out-of-pocket in India. We discuss costs transparently during consultation.
How long does it take to get results?
Typically 7–14 days from sample collection. Some panels return faster. Your psychiatrist will follow up to review the results and adjust your treatment plan accordingly.
Can pharmacogenetic testing prevent all medication side effects?
No. Genetic testing reduces the risk of certain types of side effects — particularly those related to metabolism — but cannot predict every individual reaction.
Does my child need pharmacogenetic testing before starting ADHD medication?
It's worth considering. Pediatric pharmacogenetic testing can help identify children who may not respond well to standard stimulants or who are at higher risk of side effects.
