haemodilution. Similarly, numbers of red blood cells are dependent on both the numbers of new red blood cells produced and the average life span RBC's.
On the day after delivery, the data were recorded on a predesigned questionnaire that recorded BMI, haemoglobin estimation at first antenatal visit, at 28-32 weeks (because maximum
