Ebv reactivated with recent pregnancy, also prescribed clindamycin for 6 weeks (finishing last week now) for elevated igg bartonella, wbc 4.5 (normal range per lab 3.4-10.8), is this ok or cause for concern of some sort of malignancy? 4 mths postpart

Ok: EBV antibodies especially nuclear antigen will persist all the time after old exposure. No malignancy normally Rarely associated with Lymphoma in immunocompromised persons

Medical issues: Congratulations on your new family! Your normal range WBC should not be worrisome to you. Lab tests sometimes are red flags for illness; this value is not.
