What does it mean if you have a result of many epithelial cells in a urine test?

Vaginal cells in it. Epithelial cells come from vagina and introitus and not from the urinary tract ; are a normal finding ; no cause for alarm. Squamous epithelial cells are a different matter ; could be from a squamous bladder growth. This would be uncommom in someone as young as you unless you born with bladder exstrophy.
