Summary
There is an overall increase in plasma, red blood cells (RBCs) and total blood volume. Plasma volume increases by 15% during the first trimester; accelerates in the second trimester; peaks at around 32 weeks, reaching up to 50% above non-pregnant levels; and stays elevated until term. It returns to non-pregnant levels by 6 days post-delivery. There is often a sharp rise of up to 1 litre in plasma volume within the maternal circulation at 24 hours after delivery.
