Anaemia -
low Hb concentration, depending on personalised range
le.g. age, altitude, pregnancy, etc. I
Can be accompanied by low PCV/Haematocrit.
·
Haematocrit/Packed Cell Volume:
·
proportion of blood occupied by red cells/Erythrocytes (usually 45%).
-
Reticulocyte count is high whenever there is
·
haemolysis (e.g. Hb defects, haemolytic anaemial or
bleeding,
due to increased bone marrow haematopoiesis.
