Dr prescibed azthromycin for high white blood count during pap what's the reason?

You got me... If you received an antibiotic prescription, the doctor must think there you have a bacterial infection of some sorts. Indeed, such an infection could lead to an elevated white blood cell count. But what i cannot answer from the information provided is where this infection is, or where it came from. These are good, important questions, and i suggest you contact the office and ask them.
