Red-cell assessment
Describe size, colour and shape without assigning a diagnosis from one cell.

Recognise and interpret
A stained thin blood film separates cells for microscopic assessment; morphology must be interpreted with counts and clinical context.
- Red cells form the background
- White cells are less numerous
- Platelets are small cellular fragments
White cells and platelets
Assess lineage features and distribution; a representative area is essential.
Correlate
Review the CBC, sample quality and clinical history. The reference is a normal adult film.
At the viva table
Try answering aloud, then open the suggested answer. Examiner questions vary.
01 / Is morphology alone enough for every diagnosis?
No. Counts, history and additional tests are often required.
02 / What is anisocytosis?
Variation in red-cell size.
03 / What is poikilocytosis?
Variation in red-cell shape.
04 / Why assess film quality?
Thick areas, poor staining and artefacts can distort apparent morphology.
