Anaemia: It is defined as haemoglobin (Hgb) less than 130 g/L for adult males and less than 120 g/L for non-pregnant women, and classified as mild (110–119 g/L for women and 110–129 g/L for men), moderate (80–109 g/L for both genders) and severe (<80g/L for both genders).9

Thrombocytopaenia: It is defined as a total platelet (PLT) count <150×109/L and categorised as mild (PLT, 100–150×109/L), moderate (PLT, 50–100×109/L) and severe (PLT, <50×109/L).13

Leucopenia: It is defined as a total white cell count (WCC) of less than 4×109/L.9
