My last vaginal swab showed candida and leucocytes. i had an abnormal pap smear last year. are the white blood cells anything to worry about?

Have STD tests: Leukocytes (WBC) are usually not prominent with yeast infection (Candida) and often are evidence of other infections, especially STDs. Ask for testing for chlamydia, gonorrhea, and trichomonas if not yet done. What kind of abnormal pap? If any doubt, talk to doctor about possible cervical biopsy to re-check for cancer or pre-cancerous changes, which also can cause increased leukocytes.
