Reference ranges for blood tests of white blood cells, comparing basophil amount (shown in violet) with other cells. Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. Basophils contain anticoagulant heparin, [8] which prevents blood from
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. Rather, basophilia is most often coupled with other white blood cell conditions such as eosinophilia , high levels of eosinophils in the blood. [ 1 ]
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
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 ...
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.

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 ...
Basophils, which account for a small proportion of the total leukocyte count, are phagocytic. Heparin, histamine, and serotonin are found in the basophilic granules. Mast cells are tissue basophils that are similar to blood basophils. Mast cells are normally not found in peripheral blood and are only rarely found in healthy bone marrow.
