What is Ara h 10 and Why Does the Food Zoomer Test for It?

Peanut seed oleosin protein

Ara h 10 is a peanut-derived oleosin protein that can be recognized by the immune system. Measuring IgA and IgG responses to Ara h 10 helps reveal peanut-related immune activity and possible cross-reactivity with other seed proteins, offering focused insight within the Food Zoomer panel.

About Ara h 10

Overview and History

Ara h 10 is classified as a peanut (Arachis hypogaea) seed protein in the oleosin family. Oleosins are small, hydrophobic proteins that associate with oil bodies inside seeds; several oleosins from peanuts were identified in allergen research and cataloged as distinct peanut‑related proteins. Biochemically, oleosins help stabilize lipid droplets during seed development and storage. Ara h 10 emerged in proteomic and immunologic studies that map the variety of peanut proteins capable of eliciting antibody responses, making it a useful marker for examining fine‑grain immune recognition of peanut components.

Interpreting Highs and Lows

Elevated IgA or IgG responses to Ara h 10 can indicate the immune system has recognized this specific peanut protein. Higher IgA may point to mucosal (gut) immune engagement, while higher IgG suggests systemic immune exposure; interpretation depends on whether IgA, IgG, or both are elevated and how they compare with other peanut markers on the panel. Low or absent antibody signals to Ara h 10 suggest limited immune recognition of this particular oleosin. Low results do not confirm lack of exposure or future risk; they are best interpreted alongside other Food Zoomer markers, clinical history, and symptom patterns to understand overall peanut‑related immune activity.

Featured Test

Ara h 10 is included in Food Zoomer to capture immune responses to a specific peanut seed protein that may be missed by broader peanut extracts. Measuring this marker at the peptide level helps clarify peanut‑specific patterns, detect potential cross‑reactivity with other seed proteins, and add precision to dietary decision‑making and personalized nutrition planning.

Ara h 10 FAQs

What is Ara h 10 and why is it important?

Ara h 10 is a protein found in peanut seeds that is part of the oleosin family. It can be targeted by the immune system, so testing for antibodies to Ara h 10 helps map how your body recognizes specific peanut components. That information can clarify whether immune activity centers on particular peanut proteins versus broader peanut extracts.

What does it mean if my Ara h 10 levels are low?

Low antibody levels to Ara h 10 suggest limited immune recognition of that specific peanut protein. This may reflect little recent exposure, immune tolerance to that component, or that other peanut proteins are more relevant for your immune responses. Low results should be read alongside other Food Zoomer markers and clinical information.

What does it mean if my Ara h 10 levels are high?

High IgA or IgG responses to Ara h 10 indicate the immune system has mounted a measurable response to this peanut protein. Elevated IgA points toward mucosal involvement and elevated IgG toward systemic recognition; either finding gains meaning when compared with other peanut markers and symptom history to identify patterns or possible cross‑reactivity.

Why is Ara h 10 included in the Food Zoomer?

Including Ara h 10 lets providers see immune activity against a specific peanut oleosin that broader extracts can miss. This peptide‑level data improves pattern recognition, helps identify cross‑reactivity with other seed proteins, and supports more precise interpretation within the full IgA/IgG profile.
