Welcome to HCM,
Leucocyte esterase is marker of urinary tract infection
As your urine contains 5-7 WBC/HPF and epithilial cells in fair number, leucocyte esterase positive result indicates urinary tract infection.
Your vaginal itching
seems to be due to vaginal infection
Tenderness in right side of lower abdomen can be due to PID.
You should consult your Gynecologist for examination and treatment.
Thanks for trusting Healthcaremagic and posting your query.
Hope you found my response to your query informative and helpful.
With good wishes,
Dr.Chandra Shekhar Sharma
