Polycythaemia in neonates
Neonatal elevated blood erythrocyte concentration can have a variety of causes. Note that haematological values vary in a non-linear manner from birth to adulthood. A rough guide to normal values of haematocrit in the neonatal period is:
- 1 day old : 0.55-0.65
- 4 days old : 0.50-0.58
- 2 weeks old : 0.50-0.55
