Mia is 23 years old and attends the GP as she is worried she may have contracted Chlamydia. She admits she has been unfaithful to her long-term partner and had unprotected intercourse recently with a casual partner. This recent partner informed her he has tested positive for Chlamydia. Mia has a two day history of dysuria and increased vaginal discharge.
She prefers to do a self vulvovaginal swab rather than be examined, and cannot attend GUM clinic for another two days. Urine dipstick is negative. She is allergic to tetracyclines.
Based on the likely diagnosis what is the most appropriate course of action?
