What this can and can't tell you
The results are based on research that has been peer-reviewed and published in scientific journals. It is the result of large studies that were considered statistically significant. That said, scientists' understanding of how this works is still developing, and real-world validation remains ongoing. We want to allow you to be part of that: helping you have a better understanding of how your genetics could impact your response, helping you have more productive conversations with your prescriber, and helping you feel more prepared for what's ahead.
This report is based on current, peer-reviewed research, not on established clinical guidelines. That makes it different from Inagene's other pharmacogenetic tests, which give medication and dosing recommendations your care team can act on directly.
Think of this as the latest thinking from researchers: useful, worth discussing, and one piece of your picture. It will not tell you which medication to take, and it cannot predict how much weight you will lose. Your prescriber is the right person to decide your treatment. This gives you both something more to work with.
Genetics is also only one factor. Diet, your lifestyle and other factors also matter.

The medications we cover
Weight-management medications
- Semaglutide: Ozempic®, Wegovy®, Rybelsus®
- Tirzepatide: Mounjaro®, Zepbound®
- Liraglutide: Victoza®, Saxenda®
Blood-sugar (diabetes) medications
- Gliclazide (Diamicron®)
- Glimepiride (Amaryl®)
- Glipizide (Glucotrol®)
- Glyburide (Diabeta®, Glynase®)
- Linagliptin (Trajenta®)
- Exenatide (Byetta®)
Depending on your results, your report may cover how well a medication may work for you, how you may tolerate it, and possible weight or blood-sugar effects.
Given how common these variants are, it's likely most people will have at least one finding to discuss with their prescriber.
The genes we look at
Your report is built on 9 genetic markers across five genes that current research links to weight-management medication response.
- GLP1R: one of the receptors that GLP-1 medications bind to and activate. Variants in or near this gene may influence weight-loss response and the likelihood of side effects such as nausea or vomiting.
- GIPR: a second docking point that dual-action medications like tirzepatide also use.
- PAM: helps process and activate certain hormone signals and plays a role in insulin secretion and GLP-1 signalling.
- MC4R: part of the pathway that regulates appetite and body weight.
- TCF7L2: helps regulate insulin secretion and your body's response to hormone signals released after eating.
We report only what relates to your medications. This is not a disease-risk test: it does not report your risk of diabetes, obesity or any other condition.

Genetics is one part of this. Another part is what you eat.
Support matters throughout your treatment, and the hardest challenges aren't genetic ones: getting enough protein, holding on to muscle while the weight comes off, staying hydrated, managing nausea and constipation without giving up on the treatment.
That's why three sessions with a dietitian are part of the product.
Session 1 (30 minutes). Walk through your report and build a plan for your first weeks: what to eat, how much protein, what to expect.
Sessions 2 and 3 (follow-ups). For when things change: a dose increase, a plateau, side effects, or a question you didn't have yet.
You choose when to use them and how often. Your sessions are available for 18 months from the day your results are ready.
Not the same as our clinical tests, on purpose
Inagene's other pharmacogenetic tests are built on established clinical guidelines or regulatory sources and give your care team medication and dosing recommendations they can act on. The science on weight-management medications isn't there yet. It's peer-reviewed, informative, and useful in conversation with your prescriber.

FAQS
How is this different from Inagene's other tests?
Our other tests (Complete Health, Pain & Mental Health, Women's Health, Cardiovascular Health) are built on established clinical guidelines or regulatory sources and give medication and dosing recommendations. This one is built on current research that hasn't reached clinical guidelines yet. It's informational: something to bring to a conversation with your prescriber.
Will it tell me which GLP-1 medication to take?
No. It gives you and your prescriber one more piece of information. The decision stays with the two of you.
What does “based on current research” actually mean?
It means the findings come from peer-reviewed studies, but expert bodies have not yet turned them into clinical guidelines. You can read the supporting research here:
- Genetic predictors of GLP-1 receptor agonist weight loss and side effects
- Tirzepatide leads to weight reduction in people with obesity due to MC4R deficiency
- Patients with Obesity Caused by Melanocortin-4 Receptor Mutations Can Be Treated with a Glucagon-like Peptide-1 Receptor Agonist
- Type 2 diabetes risk alleles in peptidyl-glycine alpha-amidating monooxygenase influence GLP-1 levels and response to GLP-1 receptor agonists
- Genetic determinants of variable anti-diabetic therapy responses across diverse populations with type 2 diabetes mellitus: a systematic review and meta-analysis
- Variation in TCF7L2 influences therapeutic response to sulfonylureas: a GoDARTs study
- TCF7L2 and therapeutic response to sulfonylureas in patients with type 2 diabetes
- Influence of TCF7L2 gene variants on the therapeutic response to the dipeptidylpeptidase-4 inhibitor linagliptin
Do I need to already be taking a medication?
No. Many people order before they start, so they can go into their first appointment informed. Others order after starting, to understand their early experience.
Will my doctor use this?
Your report is written to be shared, and it says clearly what the evidence does and doesn't support. Some prescribers will find it useful.
Does it test for diabetes risk, obesity risk or cancer risk?
No. This is a medication-response test only. It doesn't report disease risk of any kind.
What if my report shows no findings?
It's not guaranteed, but given how common these variants are, it's very likely you'll have at least one finding to discuss with your prescriber. Your dietitian sessions remain there either way, to support you as you navigate dietary changes through your treatment.
How do I book my dietitian sessions?
Once your results are ready, we'll email you a booking link. You choose the times that work for you. Sessions are available for 18 months from the day your results are ready.
What happens if I miss a session?
Please give at least 24 hours' notice if you need to cancel or reschedule. A missed session, or a cancellation with less than 24 hours' notice, uses one of your three.
Is this included in Complete Health or the Advantage Membership?
No. The information provided for these medications is not included in those products because it's informational only and not intended to inform clinical guidance directly.
Can I also get insights on my nutrition and fitness genetics?
Yes, that's a separate test. Take a look at Nutrition & Fitness.
How long do results take?
Once we receive your cheek swab at our Toronto lab, it generally takes 7-10 business days for your results to be ready to view on your Inagene account. You will receive email notifications when the sample is being processed and when your results are ready.
