How will my doctor know if I have chlamydia?
Your doctor may swab the inside of the vagina in women and the end of the penis in men. The sample is sent to a lab and checked for chlamydia. Your doctor may also order a urine test to determine if you have chlamydia. He or she may check you for chlamydia when you are pregnant, even if you have no signs of the infection. Chlamydia is harmful to newborns and can cause pneumonia or an eye infection (that could lead to blindness).
