Specialty care

Genetic testing that informs prescribing — it does not replace it

GeneSight is a pharmacogenomic test: a cheek swab that reports how your genes may affect the way your body processes certain psychiatric medications. NCNE offers it across Connecticut, Massachusetts, New Hampshire, Maine, Rhode Island, Virginia, and Kentucky, and the whole process happens by mail and video — there is no office to visit and no blood draw. It is genuinely useful information, and it is also frequently oversold, so it is worth being precise about what it can and cannot do. Testing is always optional, and it is never a precondition of being treated here.

A calm, private space set up for a telehealth psychiatric appointment

Who it's for: Adults who have tried several medications without a good result, who have had unusual or severe side effects, or who want more information before starting something new.

What to expect

A conversation before any test is ordered

Testing is not automatic. We look at which medications you have tried, what happened on each, and what decision is actually in front of you — then decide together whether a result would change anything. If it would not, we say so rather than ordering it.

A kit mailed to your home

If we go ahead, the laboratory sends a collection kit to your address. It is a cheek swab you do yourself, in a couple of minutes, with no needles and no lab visit, and it goes back in prepaid packaging.

Results to the prescriber first

GeneSight reports results to the ordering clinician, typically about three days after the laboratory receives your sample. That is normal for this kind of test and it is deliberate — the report is written for prescribers and reads misleadingly without context.

Reviewed with you, in plain language

We go through it together at a visit: what it found, what it changes, and just as importantly what it does not change. The report is yours to keep, and it stays relevant — your genes do not change, so it is a one-time test.

What GeneSight reports — and what it does not

The test looks at variations in genes involved in how the body absorbs, activates and clears psychiatric medications, and sorts more than 60 of them into categories reflecting how your genetics may affect that processing. That is real, actionable information. But the limits matter just as much, and the laboratory states them plainly itself:

  • It does not diagnose anything — it says nothing about whether you have depression, anxiety or any other condition
  • It does not detect medication allergies
  • It does not flag drug-drug interactions between medications you take
  • It does not tell us which medication will work best for you — no genetic test currently can
  • It informs a decision; it does not make one, and a result is never a reason to stop a medication that is working

Why how you metabolize a medication matters

Two people can take an identical dose of the same antidepressant and end up with very different amounts of it in their bloodstream, because the liver enzymes that clear it vary from person to person. Someone who clears a drug unusually fast may get little benefit at a standard dose; someone who clears it unusually slowly may get side effects that look like intolerance but are really a dosing problem. Knowing which pattern is likely can explain a confusing treatment history and can shape a starting dose — which is a different and more modest claim than predicting whether a medication will help.

When testing is worth doing — and when it is not

  • Often worth it: several medications tried without a clear result; side effects at doses most people tolerate; a strong family pattern of unusual medication responses; real anxiety about starting a first medication
  • Often not worth it: a medication that is already working well, where the result would not change the plan
  • Not a first step: a careful history explains far more treatment failures than genetics does, and the evaluation comes first either way
  • Not a substitute for follow-up: how you actually respond, measured over time, always outranks what a report predicts

How to get GeneSight testing without an office visit

  • Book a telehealth evaluation, or raise it at an existing follow-up visit
  • We discuss whether testing would change your plan — and order it only if it would
  • The kit arrives at your home; you take the cheek swab yourself and post it back
  • Results reach the practice in about three days from the laboratory receiving it
  • We review the report with you by video and adjust the plan if it warrants it

What it costs, and who bills you

The test is billed by the laboratory that runs it, not by NCNE — it is not part of your visit fee and this practice takes no share of it. GeneSight publishes that 98% of patients pay $330 or less, and that patients on Medicare Part B, Medicare Advantage and Medicaid typically pay nothing out of pocket; it also runs its own cost estimator so you can check before committing. Those are the laboratory's figures rather than ours, and coverage depends on your plan, so treat them as a guide and confirm your own cost before you decide. Nobody is ever tested here without knowing what it will cost them.

Common questions

What is GeneSight testing?
It is a pharmacogenomic test — a cheek swab that analyzes genetic variations affecting how your body processes psychiatric medications, and sorts more than 60 of them into categories accordingly. It is used to inform prescribing decisions, particularly when previous medications have not worked or have caused unusual side effects.
Does GeneSight tell you which antidepressant will work for me?
No, and be wary of anyone who says otherwise — the laboratory itself states the test does not identify which medication will work best. What it reports is how your genes may affect the way you process particular medications. That can explain past side effects, guide a starting dose and narrow a shortlist, but response is still judged the ordinary way: by trying a well-chosen medication and monitoring how you actually do.
How much does GeneSight testing cost?
GeneSight publishes that 98% of patients pay $330 or less, with a typical out-of-pocket cost of $0 for patients on Medicare Part B, Medicare Advantage and Medicaid, and it offers a cost estimator so you can check your own figure first. The laboratory bills you directly — the test is not part of your NCNE visit fee.
Is GeneSight covered by insurance?
Coverage varies by plan and by why the test is being ordered, so the honest answer is that it depends and is worth checking before you commit. The laboratory's cost estimator is the fastest way to find your own number, and we will not order a test before you know what it will cost you.
Can I do the test at home?
Yes — that is the normal route here, since NCNE is entirely telehealth. The collection kit is mailed to you, the cheek swab takes a couple of minutes, and it goes back by mail. There is no blood draw and no lab appointment.
Do I have to do genetic testing to be treated here?
No. It is offered where it would genuinely help and declined easily — most people are treated well without it, and a careful history explains more than a genetic report does. Testing is a tool, not a hurdle.
Does the report cover ADHD medications?
The GeneSight report includes medications used for ADHD alongside those for depression and anxiety. What the report covers and what NCNE prescribes are separate questions, though: this practice does not prescribe benzodiazepines or opioid-based medications, so if a specific medication is what you are looking for, raise it early and we will tell you plainly whether we are the right practice.
Do I need to be tested again later?
No. Your genes do not change, so it is a one-time test and the report stays useful for future prescribing decisions — including with other clinicians, since the report is yours to keep.

Cost

The visit is billed normally — an evaluation or a follow-up, with most major insurance plans accepted. The test itself is billed separately by the laboratory, not by NCNE. See Insurance & Fees for rates, in-network details and superbills.
