They said that it was likely just low WBC due to genetic variation. I have never had a low WBC count in the past (last cbc w/diff in 2020 was normal) and no one in my family has a low WBC count. I understand that it still could potentially be a "normal"/ genetic variant low wbc count, but are there any possible explanations for my results that have not been explored above and should I push to investigate or should I just wait and see if I start getting infections or other symptoms like they said I should? I am a student in a healthcare field and could just be over-analyzing and worried for no reason!. ### Response: I wouldn't pursue anything further with this if you don't have frequent infections or any other symptoms. Some people just run on the lower end, and that's fine..
