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 give general information on anaemia, recognise urgent symptoms, explain causes and diagnosis in general terms, and route people to appropriate care without individual medical advice.

A condition in which the blood has too few red blood cells or too little haemoglobin to carry adequate oxygen, causing tiredness, breathlessness and pallor, with many causes including iron, vitamin B12 and folate deficiency, chronic disease, blood loss, inherited disorders such as spherocytosis and thalassaemia, and bone marrow conditions; it is diagnosed by blood tests and treated according to cause.

What it is for: A common blood condition needing diagnosis of its cause.

It can be explain symptoms and types; recognise urgent warning signs; explain diagnosis and treatment by cause in general terms; support prevention through nutrition information.

Distinguishing features

Low red cells or haemoglobin

Many causes

Classified by cell size and cause

Treatable by cause

What it looks like

Not physical; diagnosed from blood counts.

How it is recognised

Low haemoglobin on a blood test

Tiredness, pallor and breathlessness

Tiredness alone has many other causes
