Tested for chlamydia using a urine sample 14 days after unprotected intercourse and the result came back "equivocal". doc said the liklihood i am positive is minimal and to retest. any further info on the equivocal thing? thanks in advance?

There has not been much research on interpretation of equivocal results, but probably roughly half are infected -- so despite your doctor's advice, there's a good chance your repeat test will be positive. If so, or if equivocal again, you should be treated with doxycycline. If doubt remains, consider contacting your nearest federally funded sexual health centre, for world class advice. Good luck.

This can happen at times. Your doc's advice seems fair.
