Blood Film in MRCP(1)

Peripheral Blood Film in MRCP(1)

Certainly before your MRCP Part 1 and 2, you need to know a very important topic in haematology, you are right, many candidates have the tendency to go to the examination without knowing anything about blood film.

You must know a few popular blood films in MRCP, before we proceed to revise a few important blood films, I think you must remember these useful terms here,

1) AniSocytosis- Variation in Size.
2) Poikilocytes- Variation in shaPe
3)

Basophilic stippling of RBCs is seen in lead poisoining, thalassemia and other dyserythropoetic anaemias

4) Blasts- Nucleated precursors cells
5) Howell Jolly bodies- Nuclear remnants seen in in RBCs especially in post splenectomy
6) Leukaemoid reaction- A marked reactive leucocytosis
7) Left shift- Immature white cells seen in circulating blood
8) Right shift- Hypersegmented polymorphs ( Image below)


9) Rouleaux formation- Red cells stack on each other
10) Target cells RBCs with central staining, a ring of pallor and an outer rim
