Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain white blood cells and their kinds, relay reference ranges and the meaning of counts in general terms from clinical references, and route personal test results and diagnoses to clinicians.

Any of the cells of the immune system found in blood and tissues that defend the body against infection and disease, including neutrophils, lymphocytes, monocytes and macrophages, eosinophils and basophils, made in the bone marrow and counted in a full blood count; white blood cells are also called leukocytes.

What it is for: Defending the body against infection and disease.

It can be explain the kinds and their functions; relay reference ranges in general terms; explain what high and low counts can mean in general; route personal results to clinicians.

Distinguishing features

Nucleated, unlike red cells

Several kinds with distinct roles

Made in bone marrow

Counted in the full blood count

What it looks like

Not visible to the eye; under the microscope nucleated cells of varied shape stained in blood films.

Physical character

normal count: about 4-11 thousand per microlitre - adults; ranges vary by laboratory

neutrophils share: about 40-70 percent - of white cells

How it is recognised

Nucleated blood cells of the immune system

Kinds distinguished by nucleus shape and granules

Red cells carry oxygen and platelets clot; both are other blood cells

What the second pass must settle

  • Should each kind be a separate entry?
  • How should reference ranges be linked by laboratory?
  • The registry entry has merged aliases for specialised tissue cells; should they be split off?
