ALLERGEN PANEL, TREE NUTS, SERUM

Additional Codes

Label Text	TRNUT
EPIC	LAB20250

Performing Laboratory

NorDx Laboratories

Useful For

Establishing the diagnosis of an allergic disease and defining the allergens responsible for eliciting signs and symptoms.
Panel Includes: Almond (F20C), Brazil Nut (F18), Cashew (F202), Hazelnut (F17), Pecan (F201), Pistachio (F203) and Walnut Juglans (F256)
The multiallergen IgE antibody test, combined with measurement of IgE, Total in serum, is a very sensitive first-order test for allergic disease. Positive results indicate a high probability of allergic disease induced by one or more allergens present in the multiallergen panel. Negative results effectively rule out allergy, except in rare cases of allergic disease induced by exposure to a single allergen.

If an IgE, Total is desired, please order individually IGET.

Method Name

ImmunoCAP® Fluorescence Enzyme Immunoassay (FEIA)

Reference Values

< 0.10 kU/L – Undetectable (Normal)

0.10 – 0.34 kU/L – For specialist use only. Clinical Relevance Undetermined

0.35 – 0.69 kU/L – Low level of allergy, indicative of ongoing sensitization

0.70 – 3.49 kU/L – Moderate level of allergy, indicative of stronger ongoing sensitization

3.5 – 17.49 kU/L – High level of allergy, indicative of high level sensitization

17.5 – 49.9 kU/L – Very high level of allergy, indicative of very high level sensitization

50 – 99.9 kU/L – Very high level of allergy, indicative of very high level sensitization

≥100 kU/L – Very high level of allergy, indicative of very high sensitization
