I'm really confused as my son has iron deficiency anaemia, now on supplements, but also neutropenia. The cause of neutropenia is not apparent. I admit, I've googled like a nutter and only bad things come up as to the cause, yet our consultant just says maybe my son has had a recent virus/infection. He hasn't had an obvious one. No symptoms. Obviously he gets tired and is pale from anaemia. Has anyone else come across this and it turned out to be nothing? I'd really appreciate any help!
