LOINC long common name : XXX allergen triggered histamine release [Units/volume] in Blood;
LOINC short name : XXX allergen BasoBnd Ab Qn;
LOINC description : Quantitative determination of histamine release in heparinized whole blood incubated
with a suspected allergen. This term is based on, but not limited in use to, IBL International's
Histamine-Release assay, which incubates whole blood samples with different concentrations
of the suspected allergen. Release of histamine occurs upon stimulation of basophilic
granulocytes with amounts depending on their sensibility to the allergen. In the Histamine-Release
assay, the percent of histamine release falls within the 100% control ( Total Histamine)
and the blank value ( Spontaneous Release). Any positive signal greater than 5% release
is regarded as allergen specific positive.;
