How we count genes and variants

We test selected DNA positions in genes and associated regions; this is not whole-gene sequencing. Each named gene is counted once, even when we test multiple variants. A variant ID is counted once across report topics. We do not add extra genes for overlapping annotations or alternate names.

These totals describe the test's coverage. They are not a count of findings that will be significant for you, and some tested markers may not appear as separate rows in your report.

Family owned

Personal service from the team behind your test.

In-house genetic testing

We own, operate, and maintain our genetic testing equipment inside a CLIA-certified laboratory.

Your data is never sold

Your genetic data is never shared with third parties. Samples are destroyed after processing.

A few helpful answers

Before you get started.

Have a question about choosing a test?
Talk with our team.

Can I understand the report on my own?

Yes. Your report is designed for you to read and understand, with plain-English explanations of your genetic findings, visual pathways, and personalized nutrition and lifestyle suggestions. You do not need a practitioner appointment to read your results. If you want extra support, you can choose to share the report with your practitioner. See how it reads in a sample report (PDF, opens in a new tab).

Does MaxFunction include MTHFR?

Yes. MaxFunction includes MTHFR-related variants and 19 genes with tested variants across methylation, folate and B12 pathways. The count includes folate and B12 genes; it is a gene count, not a count of separate topics or all variants in the panel.

Should I choose MaxFunction or The Works?

Choose MaxFunction for functional wellness topics such as methylation, histamine, hormones, antioxidants, and nutrient processing. Choose The Works if you also want expanded food, digestion, diet, weight, metabolism, and fitness insights. Compare the report topics.

What kind of sample do I provide?

A cheek swab collected at home. Your kit includes a swab, sample vial, and step-by-step instructions. Follow the collection instructions supplied in your kit.

How soon will I receive results?

Average lab turnaround is 5–7 days. You'll receive an email when your report is ready.

Does it diagnose conditions or measure current levels?

No. MaxFunction explores genetic tendencies for informational and wellness purposes. It does not diagnose disease or measure your current vitamin, hormone, or histamine levels. Consult a qualified healthcare professional before making medication or treatment changes.

Can I use Shop Pay or my HSA/FSA card?

Shop Pay payment options are displayed beneath the price and at checkout, subject to eligibility and the terms shown by Shop Pay. MaxFunction is HSA/FSA eligible; you can use your HSA or FSA card at checkout.

Is return shipping included?

US orders include a prepaid return label. Canadian and other international orders include instructions for arranging return shipping; a prepaid return label is not included.

What happens to my sample and data?

Your sample is destroyed after processing. Your genetic data is never sold or shared with third parties. Read our privacy policy for details.
