Well before the Big Day Out, its time to clear chlamydia out. Pap smears and blood tests are not the go, you need to pee in order to know. Burnet Institute

Why did the chicken cross the road? Coz it realised a pap smear or a blood test didnt test it for chlamydia. Urine samples are the best chlamydia test.
