Original MICA image-reading exercise, unscored. No clinical narrative absent from the source is added.
- Describe visible findings before proposing an interpretation.
- Suggest an interpretation and at least one image limitation.
- Which clinical findings or investigations would complement this observation?

- Document parasitaemia
- Limitation
- Single image insufficient
Morphological description
Thick films concentrate parasites; thin films better preserve erythrocytes for morphological identification.
Causes and diagnostic direction
Species identification uses several features; a thick film alone may be insufficient.
Differential diagnoses
Artefacts and other blood parasites may cause confusion; trained microscopic interpretation is needed.
Pitfalls and limitations
One initial negative film may not exclude malaria; continue testing if clinical suspicion persists.
Take-home message
Detect, identify and quantify; a teaching image cannot replace complete slide examination.
