What can abnormal WBC 11-30 indicate after taking antiobiotic?

Abnormal white blood cell (WBC) counts between 11,000 and 30,000 cells per microliter after antibiotic treatment may indicate an ongoing infection, a reaction to the antibiotic, or other underlying conditions such as inflammation or stress. Elevated WBC counts often suggest that the body is still fighting an infection despite antibiotic use. It may also signal the presence of other issues, such as an allergic reaction or a hematological disorder. Further evaluation by a healthcare professional is necessary to determine the exact cause.
