This one document contains 4 complete genetic reports. Each was scored on its own, then combined here so you can read everything in one place. Every result further down is labelled with the report it came from.
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.
Inflammation & Autoimmunity — Inflammation and autoimmunity are key processes that affect the body’s ability to maintain health and respond to threats. Inflammation is the body's natural response to injury or infection, but chronic inflammation can lead to a variety of health problems, from gut issues to systemic diseases.
Immunity & Infections — The immune system is the body’s primary defense against infections, working tirelessly to ward off harmful viruses, bacteria, and other pathogens. However, genetic factors can influence how effectively your immune system responds to various infections and how prone you may be
HLA DNA Autoimmunity — Your immune system's ability to distinguish between "self" and "non-self" is largely influenced by your HLA (Human Leukocyte Antigen) genes. These genes act like your body's security system, playing a crucial role in how your immune system recognizes and responds to various threats.
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

Flu (influenza) is a respiratory infection of the nose, throat and lungs, transferred via droplets that are either inhaled or picked up from surfaces.
Studies show that genetic factors can play a significant role in the risk of developing severe flu symptoms.

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.
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.

The most common forms of thyroiditis include Hashimoto's thyroiditis, an autoimmune disease where the body's immune system mistakenly attacks the thyroid; postpartum thyroiditis, which can occur after childbirth; and subacute thyroiditis, which usually follows a viral infection.
Diagnosis may involve blood tests to measure thyroid hormone levels, as well as antibody tests to detect autoimmune activity.
Treatment depends on the type and severity of thyroiditis, ranging from observation and symptom management to medications like levothyroxine for hypothyroidism or beta-blockers for hyperthyroidism symptoms.
