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 54 results here, 9 came back worth discussing with a clinician and 2 came back in your favour. Bring this document to your appointment.

What this package looks at

Gluten Sensitivity — Why do some people react strongly to gluten while others can eat it without issue? The answer often lies in our genes, particularly in the HLA gene family. This report examines genetic factors that influence both celiac disease and non-celiac gluten sensitivity, mapping out how different

Histamine — Histamine is a crucial molecule that plays multiple roles in your body, from immune responses to neurotransmitter function and digestion. This analysis explores genetic variations that influence every aspect of histamine metabolism -from production and storage to breakdown and

Mold Sensitivity — Your body's response to mold exposure -whether through air or food -can vary significantly based on your genetic makeup. This report examines genetic variations affecting multiple systems involved in mold response: your immune system's recognition of mold particles, your detoxification

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.

Your headline findings

Of the 54 results in this package, these 8 came back furthest from the population average. Each one below explains what it is, where you sit, and which report it came from. Start here.

Skin Rash (Allergic)More likely
Higher predisposition than 99% of people
Your result sits higher than 99% of the population.

What this actually is

Identifying and avoiding contact with the allergen is the most effective strategy to manage allergic contact dermatitis.

Some preventive measures that may help include: Protective clothing: Wearing gloves or other protective clothing can help prevent skin contact with allergens.

Careful product selection: Opting for hypoallergenic More likely to have products and carefully reading labels to avoid known based on 16,669 allergens.

What you can do

  • Elimination Diet
    Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.
  • Topical Capsaicin
    Avoid contact with eyes, mouth, and other sensitive areas.
  • Avoid Scratching
    Choose a moisturizer suited for your skin type; for sensitive skin, opt for fragrance-free options.
From your Allergies report
HivesMore likely
More likely to have hives based on 12,371 genetic variants we looked at
Your risk is greater than 99% of the population and lower than 1% of the population.

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.
  • Elimination Diet
    Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.

Ask your clinician about

  • Maintain Optimal Vitamin D Levels

Named only. Marrow gives no dose and does not recommend these.

From your Allergies report
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.

Ask your clinician about

  • Quercetin
  • Dietary Omega-3 Fatty Acids
  • Vitamin C

Named only. Marrow gives no dose and does not recommend these.

From your Histamine report & Allergies
Food AllergiesMore likely
More likely to have food allergies based on 16,808 genetic variants we looked at
Your risk is greater than 95% of the population and lower than 5% of the population.

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
    Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.

Named only. Marrow gives no dose and does not recommend these.

From your Allergies report
Egg AllergyMore likely
More likely to have an egg allergy based on 373 genetic variants we looked at
Your risk is greater than 80% of the population and lower than 20% of the population.

What this actually is

Egg allergies are relatively common, especially in children, and can be very severe.

A person usually develops a reaction to one or more egg white proteins.

Luckily, the allergy often fades with age [R, R].

What you can do

  • Elimination Diet
    Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.
From your Food Sensitivities report & Allergies

A further 1 results were also flagged for attention. They are listed below and explained in full in the technical version of this report.

Where your genetics are working for you

Not everything in a genetic report is a warning. These came back protective or better than average.

Allergic Eye IrritationLess likely
Less likely to have allergic eye disease based on 740 genetic variants we looked at
Your risk is greater than 2% of the population and lower than 98% of the population.

What this actually is

Management of allergic eye disease often involves a combination of treatments and preventive measures.

If symptoms persist or worsen, it’s important to consult a healthcare provider to ensure appropriate management and avoid complications.

Identifying and minimizing exposure to the allergens that trigger symptoms is the most important preventive measure.

From your Allergies report
HRH2 (Gut Health)Better genetics
Lower predisposition than average

What this actually is

The most widely-investigated HRH2 polymorphism is rs2067474 (-1018 G>A).

Its minor ‘A’ allele may affect gene expression based on its position within the gene sequence but its exact contribution to HRH2 function hasn’t been established.

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.
