Overview
Lab tests
A swab is inserted 1–4cm into the urethra and rotated once. The swab is then smeared onto a glass slide and examined under a microscope. A commonly used cut-off for the diagnosis of urethritis is 5 or more polymorphs per high power field, but this definition has recently been called into doubt.[1]
Tests of gonorrhoea and chlamydia are sent on the swab.
