What is the reference range for Soybean Specific IgE?

The standard reference range for Soybean Specific IgE is Class 0 (<0.35 kU/L) negative; higher classes indicate greater sensitisation.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

What does the Soybean Specific IgE test measure?

Q: What is Soybean Specific IgE?

Soy allergens include the storage proteins Gly m 5 (beta-conglycinin) and Gly m 6 (glycinin) and the Bet v 1 homologue Gly m 4. Gly m 4 sensitisation commonly arises secondary to birch-pollen allergy and tends to cause mild, oral symptoms, whereas storage-protein IgE is more often associated with systemic reactivity.

Q: Why is Soybean Specific IgE measured?

A positive soy sIgE in a birch-sensitised patient frequently reflects pollen cross-reactivity rather than primary soy allergy. Distinguishing the two shapes risk counselling, and the whole-extract panel result cannot make that distinction on its own — component resolution is required.

Soybean Specific IgE (f14 Soy sIgE) is a clinical biomarker used in food-sensitivity-allergy assessment. Soy allergens include the storage proteins Gly m 5 (beta-conglycinin) and Gly m 6 (glycinin) and the Bet v 1 homologue Gly m 4. It is measured in 1 laboratory test on BiomarkersLabs.com.
