Term Description

The percentage of basophiles activated after in vitro stimulation by allergens and expressing the CD63 marker can be determined by flow cytometry. This allergy test method is a blood test for identification of the allergen (e.g. bee venom, drugs, etc.) responsible for the hypersensitivity reaction. It is not the same as the common scratch test.

Part Description

LP183573-7   Basophils.CD63
Activation of basophilic granulocytes with anti-IgE and the expression of the CD63 antigen on the cell surface allows identification of an allergy. Basophiles, along with mast cells, are considered to be the key cells in allergic diseases. Hypersensitivity reactions are caused by an initial systemic histamine release by activated basophiles and mast cells, which may lead to shock with laryngeal edema, lower-airway obstruction and hypotension. The index method for this test establishes the basophil population by use of low SSC (side scatter) and a human chemokine receptor CCR3 marker.

Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component;
