What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

When is it used?

Used in lab systems, EHRs, and clinical data exchange.
May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
Status: ACTIVE
Order vs observation: Both
Method: IA

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Multiple inhalant allergen IgE Ab [Presence] in Serum by Immunoassay

Multiple inhalant allergen Ab.IgE

This term was created for (but not limited to) Siemen's Immulite 2000 AlaTOP allergy screen, a chemiluminescent enzyme-labeled sequential immunoassay used to qualitatively detect IgE antibodies specific to inhalant allergens in serum. The AlaTOP constituents usually include the following 12 allergensDermatophagoides pteronyssinus (dust mite), cat epithelium, dog dander, Cynodon dactylon (Bermuda grass), Phleum pretense (timothy grass), Penicillium notatum, Alternaria tenuis, Ambrosia artemisiifolia (common ragweed), Plantago lanceolata (English plantain), Parietaria officinalis (wall pelitory), Betula papyrifera (paper birch), and Cryptomeria japonica (Japanese cedar) (Source: http://www.cdc.gov/niosh/hhe/reports/pdfs/2005-0248-3077.pdf) The Phadiatop assay has a fixed set of allergens that is not stated by the manufacturer (http://www.jiaci.org/issues/vol15issue02/7.pdf), but probably contains a similar subset of components. Test results are determined by the calculation of a signal to cutoff (S/CO) ratio, which is calculated automatically by the instrument. The results are reported as indeterminate (ratio between 0.9 and <1.1), reactive (ratio of >=1.1) and nonreactive (ratio of < 0.9).
