So since 2021 on my blood results it reads nucleated red blood cells under 0.3 , before this it was always 0 and i have read online that this indicates a problem . No doctor has ever mentioned it and i only became aware when viewing my health record for a job health check . What should i do about this ? Is this common or an issue ? From reading online it is only bad news even in small numbers and it has been like this for over two years ?
