Histamine
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 12 results here, 1 came back worth discussing with a clinician and 1 came back in your favour. Bring this document to your appointment.

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.
