hemolytic anemia
Let an agent explain haemolytic anaemia in general terms, relay causes, types, signs, tests and treatment approaches from haematology sources, route severe symptoms to emergency services, describe the named forms and note the syndrome alias, and distinguish haemolytic anaemia from iron deficiency anaemia, aplastic anaemia, anaemia from blood loss and jaundice from liver disease, without diagnosing individuals.
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 haemolytic anaemia in general terms, relay causes, types, signs, tests and treatment approaches from haematology sources, route severe symptoms to emergency services, describe the named forms and note the syndrome alias, and distinguish haemolytic anaemia from iron deficiency anaemia, aplastic anaemia, anaemia from blood loss and jaundice from liver disease, without diagnosing individuals.
Anaemia caused by red blood cells being destroyed faster than the bone marrow can replace them, either within blood vessels or in the spleen and liver, with inherited causes such as sickle cell disease, thalassaemia, hereditary spherocytosis, hereditary pyropoikilocytosis and G6PD deficiency, grouped as congenital haemolytic anaemias, and acquired causes such as autoimmune haemolytic anaemia, including neonatal forms and Evans syndrome with low platelets, infections such as malaria, drugs, toxins and mechanical damage; the registry alias STAT3-related early-onset multisystem autoimmune disease names a genetic immune dysregulation syndrome that can include autoimmune cytopenias. Signs include fatigue, pallor, jaundice and dark urine, and severe breathlessness, chest pain or collapse needs emergency services.
What it is for: Not applicable; a group of blood disorders.
It can be explain causes and types; relay signs and tests in general terms; describe named forms; route severe symptoms.
Distinguishing features
Shortened red cell survival
Raised reticulocytes
Jaundice
Diverse causes
What it looks like
Not visible directly; signs include pallor, jaundice and dark urine.
Physical character
normal red cell lifespan: about 120 days
key tests: reticulocyte count, bilirubin, LDH, haptoglobin, direct antiglobulin test list
classification: intrinsic or extrinsic, inherited or acquired note
How it is recognised
Anaemia from red cell destruction
Evans syndrome, STAT3-related early-onset multisystem autoimmune disease, autoimmune haemolytic anaemia, congenital haemolytic anaemia, hereditary pyropoikilocytosis, neonatal autoimmune haemolytic anaemia
Iron deficiency reduces production; aplastic anaemia is marrow failure; blood loss anaemia follows bleeding; liver jaundice has other causes

What the second pass must settle
- The registry alias STAT3-related early-onset multisystem autoimmune disease should be moved to immune dysregulation entries
- Should each named form be a separate entry?
- How should haematology guidelines be linked?
