Getting a GeneSight Test: Swab, Turnaround, Cost Questions and Your Results Visit

By Dr. Stacey Forbes, DNP, APRN, PMHNP-BC · Updated October 12, 2026

Key Takeaways

  • A GeneSight test has to be ordered by a prescribing clinician; you cannot buy the clinical test on your own.
  • The cheek swab can be done in the office or with a kit mailed to your home, and the lab will not process a sample without your signed consent form.
  • GeneSight says results typically reach your clinician about three days after the sample arrives at the lab, so shipping time comes on top of that.
  • GeneSight says it will contact you before processing if your cost could go above $330, so you can decide whether to go ahead.
  • Keep taking your current medications exactly as prescribed while you wait; changes come after the results visit, not before.

Getting a GeneSight test takes less effort than most people expect: a clinician places the order, you rub two swabs on the insides of your cheeks, and the sample travels to the lab in a prepaid envelope. The parts that take more thought are the paperwork, a possible call from the testing company about cost, and the visit where you go over the report. This guide walks through each step in order, with what the company itself says about timing and cost today, and what to do in the days between swab and results.

Step 1: a clinician decides the test is worth ordering

GeneSight is a clinical laboratory test, so it starts with a prescriber. The company states that the test must be ordered by a prescribing clinician who is registered to offer it. There is no way to order this clinical test for yourself.

Before ordering, a careful prescriber asks a simple question: would the result change anything? At Willow & Stone, pharmacogenomic testing is ordered when it is clinically useful, most often after one or more medications have not worked or caused side effects that were hard to live with. It is part of ongoing care, not a test-only service, so the order usually comes out of a visit where your medication history has already been reviewed in detail.

If you want the background on what the test measures and how it fits into treatment, the GeneSight testing overview covers that. This page stays with the practical steps.

Step 2: the cheek swab, in the office or at home

There are two ways to collect the sample. You can swab in the office during a visit, or your clinician can have a collection kit sent directly to your home. The at-home route means no in-person visit is needed, which is how many telehealth patients do it.

According to GeneSight’s at-home instructions, the kit includes swabs, a DNA sample envelope, a patient consent form, financial information and a prepaid FedEx return envelope. The collection itself goes like this:

  1. Do not eat or drink for 15 minutes before you swab.
  2. Rub the first swab firmly up and down against the inside of one cheek, then use the second swab on the other cheek, following the stroke count printed in the kit.
  3. Let the swabs go into the sample envelope as the instructions show, and fill in every field on the envelope. GeneSight notes that the billing fields matter.
  4. Read and sign the consent form. The company says samples are not processed without it.
  5. Seal everything in the prepaid FedEx envelope that came with the kit. Using that envelope is what gets the sample to the lab overnight.

The most common reason for a delay is a missing signature or an incomplete envelope, not the swab itself. Taking two extra minutes to check the paperwork saves days.

Step 3: turnaround, and what “about three days” means

GeneSight says results are typically available to your clinician about three days after your kit reaches its lab. That clock starts when the lab receives the sample, so add the time it takes to collect, ship and log the kit. If you swab at home on a Friday evening, the realistic window is longer than if the swab goes out from an office on a Monday morning.

Results go to the ordering clinician first. The clinician can share a digital copy with you, and GeneSight also offers a Patient Report Request Form for people who cannot get a copy from their clinician, which the company says typically takes two to four weeks. Most people find it easier to get the report through their prescriber and go over it together.

Step 4: the cost questions the testing company may ask

The GeneSight test is billed by the testing company, Myriad Genetics, not by Willow & Stone. That means any conversation about the cost of the test itself happens between you, your insurer and the company. The practice can explain the process, but it does not set the price or send the bill.

GeneSight’s cost page describes how it handles this. If your cost through insurance could exceed $330, the company says it will contact you before processing the test and before billing you, so you can decide whether to proceed. It also states that 98% of patients pay $330 or less, based on its review of 12 months of claims from major US insurers. That figure is the company’s own, and your plan is what decides your share.

Other points the company lists, which you may be asked about when it calls:

Answer the phone or call back if the company contacts you; it is the step that prevents a surprise bill. How plans decide coverage in the first place is covered in our guide to GeneSight and insurance, and visit costs at the practice are on the pricing page.

While you wait: keep everything the same

The days between swab and results can feel like a pause button, and it is tempting to start acting on a hunch. Please don’t. Stopping or lowering a psychiatric medication on your own, especially an antidepressant, can bring on discontinuation symptoms or a return of the symptoms it was treating, and a genetic report will not change that risk.

A few things are worth doing while you wait:

Call your prescriber today if…

…a current medication is causing side effects you cannot tolerate, your mood is getting noticeably worse, or you are thinking about stopping a medication. Waiting for a genetic result is not a reason to wait on those calls. If you are thinking about suicide or feel unsafe, call or text 988, text HOME to 741741, or call 911.

Step 5: the results visit

The report is written for clinicians, and the visit is where it becomes useful. At Willow & Stone, results are reviewed with you by telehealth or in person, side by side with your history, symptoms, other medications and any lab work. The report is one data point. It never decides a medication on its own.

Expect the conversation to cover:

For a walk-through of the report layout itself, see how to read your GeneSight report. If the report lists metabolizer types, the guide to CYP2D6 and CYP2C19 metabolizer types explains what those labels mean.

After the visit: keep the report

Your genes do not change, so this report can stay useful for years. Ask for a digital copy, store it somewhere you can find it, and share it with your primary care clinician and pharmacist if you would like them to have it. Why pharmacogenomic results can matter for the rest of your life covers how to share it and when an older report may need a fresh look.

If you are still deciding whether testing makes sense for you, five things nobody tells you about GeneSight is a candid place to start.

Common Questions

Can I order a GeneSight test myself?

No. GeneSight states that the test must be ordered by a prescribing clinician who is registered to offer it. Your clinician places the order, and the kit can then be sent to your home or the swab done in the office. Consumer DNA kits you can buy yourself are a different kind of product and are not a substitute for a clinical pharmacogenomic test.

How long do GeneSight results take?

GeneSight says results are typically available to your clinician about three days after the kit arrives at its lab. Add the time it takes for the kit to reach you, for you to swab and sign, and for the courier to deliver it back. Results go to your clinician first, who then reviews them with you.

Do I need to fast before the cheek swab?

No fasting is needed. GeneSight’s at-home instructions say not to eat or drink for 15 minutes before swabbing, so the sample is not diluted by food or drink. Follow the kit’s own instructions for how many strokes to use on each cheek, and sign the consent form, because the lab will not process an unsigned sample.

Will I get a surprise bill for GeneSight?

GeneSight says that if your cost through insurance could exceed $330, it will contact you before processing the test and before billing you, so you can decide whether to continue. It also offers an interest-free payment plan for costs of $100 or more. The test is billed by the testing company, not by Willow & Stone, so cost questions go to the company.

Should I stop my medication before the test?

No. The test reads your DNA, and your medications do not change your genes, so there is no reason to stop anything to get an accurate result. Keep taking everything exactly as prescribed, and bring a complete list, including supplements, to your results visit. Any change should come from your prescriber.
