About this report
This report reads your DNA and sorts every result into one of five plain-language groups, so you can see at a glance what deserves attention and what does not. Nothing here is a diagnosis. A flagged result means your genetics place you above or below the average person for that trait — a reason to ask a question, not a reason to worry.
What each result group means
Worth a conversation with your doctor
These came back with a higher genetic predisposition than most people. That is not a diagnosis — it means these are the ones worth raising at your next appointment.
Running above the typical range
Your genetics point to these sitting higher than average. Often useful to know, sometimes worth monitoring.
Running below the typical range
Your genetics point to these sitting lower than average. Same idea — context, not alarm.
Working in your favour
Good news. Your genetics look protective or better than average here.
In line with most people
Nothing unusual. These were tested and came back typical — worth having on record.
Your results at a glance
How to read this. A result being flagged does not mean you have a condition — it means your genetics put you above or below the average person for that trait. Of the 72 results here, 17 came back worth discussing with a clinician and 8 came back in your favour. Bring this document to your appointment.
What this package looks at
Skin & Beauty — As we age, our skin starts to sag and develop wrinkles, our hair begins to gray and thin, and we long for the looks of our younger days. However, even those younger days can have issues like acne or eczema. Our skin is our biggest organ and exposed to the environment more than any other.
Hair Health — Your hair tells a unique story—one that's written in your genes. This report explores how genetic makeup influences various aspects of hair health like hair loss, dandruff, and more. We also analyze how you may respond to different hair regrowth strategies.
What you can actually do
These are ordered by how closely they relate to your flagged results — not generic health advice. Marrow does not prescribe, dose, or tell you to take anything. Diet and lifestyle changes are listed first because they are yours to make. Anything you would swallow is listed separately, by name only, as something to raise with a clinician who knows your history and your medications.

What this actually is
Key Takeaways: Your genetics plays a factor in developing hives through inflammation signaling and histamine levels.
Chronic hives are more common in women.
Risk factors include previous allergic reactions and your genetics.
What you can do
- Avoid Food Triggers
Identify foods that trigger negative reactions in your body, such as digestive issues, allergies, or headaches, and eliminate them from your diet entirely. - Moisturize the Skin

More likely to have droopy eyelids based on 240,468 genetic variants we looked at
Your risk is greater than 97% of the population and lower than 3% of the population.
What this actually is
Eyelid drooping is excess sagging of the upper eyelid.
The eyelid may be sitting lower than it should (ptosis) or drooping due to loose or excess skin (dermatochalasis).
About 60% of the differences in people’s eyelid drooping may be due to genetics.
What you can do
- Moisturize the Skin

Excessive Mast CellsMore likely
More likely to have excessive mast cells based on 14 genetic variants we looked at
Your risk is greater than 97% of the population and lower than 3% of the population.
What this actually is
Mastocytosis is often linked to mutations in the KIT gene, which plays a role in mast cell growth and development.
These mutations are usually acquired during a person's life rather than being inherited.
Other, less important risk factors include: Family history: Rare cases may run in families, but most are sporadic.

What this actually is
Key Takeaways: Up to 80% of differences in people's chances of having food allergies may be attributed to genetics.
Many allergies come and go through childhood, but common ones that linger into adulthood include nuts, seafood, milk, and eggs.
Reducing risk for allergies involves avoiding the various food triggers.
What you can do
- Avoid Food Triggers
Identify foods that trigger negative reactions in your body, such as digestive issues, allergies, or headaches, and eliminate them from your diet entirely. - Elimination Diet

Stretch MarksLess likely
Less likely to have stretch marks based on 1,519 genetic variants we looked at
Your risk is greater than 1% of the population and lower than 99% of the population.
What this actually is

What to do with this
Genetics is a predisposition, not a verdict. The single most useful thing you can do with this document is take it to a clinician and talk through the flagged findings — especially any that line up with symptoms you already have or conditions that run in your family. Nothing here changes: your DNA is the same at 60 as it is today, so this report does not expire.
Methodology
Genotyping was performed on DNA extracted from a buccal (cheek) swab using a genome-wide array. Results are derived from peer-reviewed genome-wide association data and, where applicable, published clinical guidelines. Each report was scored independently against its own reference set. Percentile figures describe where your result sits relative to a reference population.
Limitations
This is a laboratory-developed test. It has not been cleared or approved by the U.S. Food and Drug Administration. Genotyping does not detect all variants in the genes assessed; the absence of a flagged result does not exclude risk. Predisposition is probabilistic and is modified by environment, lifestyle, ancestry and family history. Results must be interpreted by a qualified healthcare professional and must not be used alone to diagnose, treat, or alter any medication regimen. Marrow does not recommend, prescribe, or dose any supplement or medication.
