What is Gly m Bd 30k and Why Does the Food Zoomer Test for It?

Soy seed protein allergen

Gly m Bd 30k is a ~30 kilodalton protein derived from soybean (Glycine max) that can be targeted by the immune system. Measuring IgA and IgG responses to this soy protein helps reveal whether the body shows mucosal or systemic immune reactivity to soy, adding context to other Food Zoomer markers.

About Gly m Bd 30k

Overview and History

Gly m Bd 30k is classified as a soybean-derived protein antigen from the plant Glycine max. Biochemically it is a ~30 kDa seed protein that has been identified as an antigenic target in food-sensitivity and allergy research and appears on laboratory arrays as a discrete soy-derived marker. In seeds, proteins of this class function as nutrient stores for germination. In humans, fragments of the protein can be recognized by antibodies at mucosal surfaces or systemically; its reproducible immune recognition in studies is why it was included among testable soy antigens.

Interpreting Highs and Lows

Elevated antibody levels to Gly m Bd 30k generally indicate measurable immune recognition of this soy protein, which can reflect recent or repeated exposure and the immune system’s engagement. Higher IgA suggests mucosal (gut-associated) activity, while higher IgG suggests broader systemic immune exposure. Low or undetectable levels suggest little or no measurable antibody response to this specific protein, but do not rule out non-antibody reactions or reactivity to other soy components. Interpretation is most meaningful when viewed alongside the full Food Zoomer panel, isotype patterns, and peptide-level results to identify broader dietary or cross-reactive patterns.

Featured Test

Gly m Bd 30k is included to assess immune reactivity to a specific soy protein at the peptide level. Combined with dual IgA/IgG measurement and other soy markers, it helps clinicians spot soy-centered immune patterns and supports personalized dietary planning and targeted reintroduction strategies.

Gly m Bd 30k FAQs

What is Gly m Bd 30k and why is it important?

Gly m Bd 30k is a specific protein found in soybeans that some people’s immune systems recognize. Testing for antibodies to this protein can help show whether soy is part of a pattern of immune activity. That information helps providers interpret whether soy exposure may be related to a person’s symptoms when seen with other panel results.

What does it mean if my Gly m Bd 30k levels are low?

Low levels mean there’s little or no measurable antibody response to this particular soy protein. That can reflect limited exposure, lack of immune recognition, or that other soy components are more relevant. Low results should be read alongside other Food Zoomer markers and clinical context to understand overall dietary immune patterns.

What does it mean if my Gly m Bd 30k levels are high?

Higher antibody levels indicate measurable immune recognition of the Gly m Bd 30k protein and can reflect repeated exposure or sensitization to that soy antigen. The pattern of IgA versus IgG helps suggest whether the response is more mucosal (gut-related) or systemic. Elevated results require interpretation with the full test panel and clinical history to clarify relevance and potential cross-reactivity.

Why is Gly m Bd 30k included in the Food Zoomer?

Measuring Gly m Bd 30k helps detect soy-specific immune responses at the protein and peptide level and, when paired with dual IgA/IgG data, clarifies whether reactivity is mucosal or systemic. This contributes to identifying clustered immune patterns, informing focused dietary decision-making and personalized nutrition planning.
