| LOINC code | 44554-4 | ||
|---|---|---|---|
| name | Deprecated Hymenopterase IgE Ab RAST class [Presence] in Serum | ||
| status | DEPRECATED | ||
| status reason | Ambiguous - Term deprecated because there is no substance called "hymenopterase" that is used in allergy testing. Hymenoptera is the general name for stinging insects, and allergy to each insect is tested individually. Recommend using the specific LOINC code for the stinging insect or stinging insect venom of interest. | ||

History/Usage | |||
| first released | |||
| last updated | 2.65 | ||
| last change type | DEL - delete (deprecate) | ||
| change reason | The Property has been changed from ACnc to Threshold to reflect the new model for ordinal terms where results are based on a cut-off value.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The Answer list type has been changed from 'Normative' to 'Example' due to the variability of the calibrator and the number of classes. Some labs use a low calibrator of 0.1 KU/L and include an additional 0/1 class, while other labs have continued with the 0.35 KU/L calibrator and have only 7 classes. | ||
