I've had a low (though not abnormally low) neutrophil count for years, all other counts and wbc normal, no symptoms of leukemia/lymphoma, should i be worried?

Evaluation: You should evaluated to find cause of neutropenia, especially blood test for neutrophil antibody.

No: A neutrophil count in the normal range (albeit at the lower end) is not cause for concern. Rest easy. Any significant illness causing low neutrophils (such as autoimmune antibody-mediated neutropenia) would manifest as recurrent infection and mouth ulcers. Thanks for trusting HealthTap!
