reticulocytes

A

immature red cells

18
Q

rod forms

A

eliptical red cells -> associated with iron def., chronic inflamm. and renal impairment

19
Q

schistocytes

A

red cell fragments -> associated with intravasc. haemolysis (e.g. DIC)

20
Q

spherocytes

A

round dark red cells (autoimmune haemolysis & Hereditary Spherocytosis)

21
Q

stomatocytes

A

red cells with slit or ‘stoma’ -> associated with alcohol, liver disease, some drugs and chlorpromazine

22
Q

target cells

A

red cells with bullseye appearance -> associated with thalassaemias, alcohol & liver diseases

23
Q

thrombocytopenia

A

low platelet count (may be false - due to platelet clumping from improper collection or EDTA-induced)

24
Q

thrombocytosis

A
