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
More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give limits on both standard and optimal (or target) ranges.

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 ...
The cell images are displayed to a human operator, who can manually re-classify the cells if necessary. [75] Most analyzers take less than a minute to run all the tests in the complete blood count. [58] Because analyzers sample and count many individual cells, the results are very precise. [76]
Neutrophils are the most abundant white blood cells in the human body (approximately 10 11 are produced daily); they account for approximately 50–70% of all white blood cells (leukocytes). The stated normal range for human blood counts varies between laboratories, but a neutrophil count of 2.5–7.5 × 10 9 /L is a
The normal white cell count is usually between 4 × 10 9 /L and 1.1 × 10 10 /L. In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood. [7] White blood cells make up approximately 1% of the total blood volume in a healthy adult, [8] making them substantially less numerous than the red blood cells at ...
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.
