Basophils have protein receptors on their cell surface that bind IgE, an immunoglobulin involved in macroparasite defense and allergy. It is the bound IgE antibody that confers a selective response of these cells to environmental substances (e.g., pollen proteins or helminth antigens).
A test tube is prepared with basophil stimulation buffer (BSB) including Interleukin 3 and an allergen which is to be tested. The blood sample is added and the tube is incubated at 37 °C for several minutes, to ensure that the allergens can bind to the IgE. By adding EDTA to the test tube, the degranulation process is stopped immediately ...

Researchers have identified protein signatures in blood tests that can be used to detect or predict up to 67 diseases, using UK Biobank data in a cohort of nearly 42,000 participants.
There are four types of granulocytes (full name polymorphonuclear granulocytes): [3] Basophils; Eosinophils; Neutrophils; Mast cells; Except for the mast cells, their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neutrophil granulocyte, which has neutrally staining cytoplasmic granules.
Complete blood count and blood smear. Basophilia is the condition of having greater than 200 basophils /μL in the venous blood . [ 1 ] Basophils are the least numerous of the myelogenous cells, and it is rare for their numbers to be abnormally high without changes to other blood components.
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
A new approach to a routine blood test could predict a person’s 30-year risk of heart disease, research published Saturday in the New England Journal of Medicine found.. Doctors have long ...
