This is the blood film of a patient with blurred vision.
a. What does the blood film show?
The red blood cells stacked together like coins and this occurs with
increased serum proteins especially fibrinogen and globulins. These long
chains of red blood cells allows the cells to sediment more rapidly and
therefore high ESR (erythrocyte sediment rate).
b. List some haematological condition which may be responsible
for this appearance.
