Anaemia is a global disease, affecting over 1 billion people worldwide; 12% of Australian women experience anaemia in pregnancy. Professional bodies/institutions recommend screening for and treating anaemia in pregnancy but there is inconsistency in recommendations for when to screen. A ten-year retrospective analysis was undertaken of 10 518 pregnancies where there was not a specific indication for repeat blood tests. Using a 28-week haemoglobin (Hb) threshold of ≥110 g/L, seven out of ten could safely forego a routine 36-week full blood count. Less than 2.5% would then be anaemic at 36 weeks, none of whom would have had a Hb < 90 g/L.
