Quest and ARUP also print a result under 0.10 kU/L as class 0, and a printed 0.10 is already class 0/1 (Labcorp 'equivocal/low'). ARUP calls 0.10 to 0.34 'clinical relevance undetermined' and says results in that range are for specialist use, and Quest calls it a very low level. Thermo Fisher, which makes the ImmunoCAP system, says results of 0.1 kUA/L or more indicate sensitization. The older 0.35 kU/L cutoff is still used in many studies, including the US NHANES survey. A result above the range shows sensitization, not that you have an allergy (NIAID 2010), and results from different labs or assay systems may not be comparable. For shrimp, IgE often reflects tropomyosin, which is shared with dust mites and cockroaches, so a positive result can come from mite or cockroach sensitization (Thermo Fisher; NIAID 2010).","sources":[{"title":"F024-IgE Shrimp (test 602473)","url":"https://www.labcorp.com/tests/602473/shrimp","publisher":"Labcorp"},{"title":"Sample patient report: F024-IgE Shrimp (test 602473)","url":"https://files.labcorp.com/testmenu-d8/sample_reports/602473.pdf","publisher":"Labcorp"},{"title":"Allergen, Food, Shrimp (test 0055030)","url":"https://ltd.aruplab.com/Tests/Pub/0055030","publisher":"ARUP Laboratories"},{"title":"ImmunoCAP Specific IgE Blood Test: Allergy Test List (interpretation table and test codes)","url":"https://www.questdiagnostics.com/content/dam/corporate/restricted/documents/hcp/about-our-tests/TL3930_Allergy%20Test%20list%202017.pdf","publisher":"Quest Diagnostics","year":2017},{"title":"Your quick guide to using ImmunoCAP Specific IgE testing","url":"https://corporate.thermofisher.com/content/dam/phadia/library/en/Quick_guide_to_using_ImmunoCAP_Specific_IgE_testing.pdf","publisher":"Thermo Fisher Scientific (Phadia)"},{"title":"Allergen Encyclopedia: f24 Shrimp","url":"https://www.thermofisher.com/phadia/wo/en/resources/allergen-encyclopedia/f24.html","publisher":"Thermo Fisher Scientific (Phadia)"},{"title":"Guidelines for the Diagnosis and Management of Food Allergy in the United States: Report of the NIAID-Sponsored Expert Panel","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4241964/","publisher":"NIAID / Journal of Allergy and Clinical Immunology","year":2010},{"title":"Allergens and molecular diagnostics of shellfish allergy: Part 22 of the Series Molecular Allergology","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC5306157/","publisher":"Allergo Journal International","year":2016},{"title":"Prevalence of allergic sensitization in the United States: results from the National Health and Nutrition Examination Survey (NHANES) 2005-2006","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC4119838/","publisher":"Journal of Allergy and Clinical Immunology","year":2014},{"title":"Allergy Blood Test","url":"https://medlineplus.gov/lab-tests/allergy-blood-test/","publisher":"MedlinePlus (National Library of Medicine)"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
