Soybean Component Panel

Test Code
18718


CPT Codes
80346 G0480

Includes
Gly m 4 (f353) IgE
Gly m 5 (f431) IgE
Gly m 6 (f432) IgE


Methodology
Immunoassay (IA)

Reference Range
Gly m 4 (f353) IgE<0.10 kU/L
Gly m 5 (f431) IgE<0.10 kU/L
Gly m 6 (f432) IgE<0.10 kU/L


Clinical Significance
Soy component testing may help manage patients with suspected soy allergy. IgE antibody against Gly m 4 may be due to cross-reactivity with Birch pollen (t3) but can still cause mild (mostly oral mucosal) symptoms after ingestion of soy products. Sensitization to Gly m 5 and/or Gly m 6 is more likely to represent true soy allergy and is also associated with more severe systemic reactions.
