IgE to Alpha-Gal is the likely cause of anaphylactic reactions in individuals who develop hypersensitivities to beef, pork and/or lamb as adults. Procedure Solid phase immunoassay with alpha-galactose-1-3-galactose as the bound antigen. Calibrated against total IgE standards from WHO Reference 75/502 to generate results in kilounits of IgE. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration. Turnaround Time 1-2 business days from receipt of specimen Specimen Information Specimen Type Order Code CPT Code NY Approved Volume Assay Range serum 30039 86008 Yes 0.5 mL (min. 340 uL) 0.1 -100 kU/L Special Instructions - Collect 1-2 mL whole blood in red top tube. - Centrifuge and transfer 0.5 mL serum into a transfer tube. - Ship at ambient or frozen temperature Monday through Friday. - Specimens are stable for 4 weeks refrigerated or ambient; freeze for longer storage. The reference range for Alpha Gal IgE is < 0.10. Level at or above 0.1 indicates IgE is detected and patient is at risk for an allergic reaction. Causes for Rejection Lipemic samples may lead to rejection Disclaimer Specimens are approved for testing in New York only when indicated in the Specimen Information field above.
