When a male takes a urethra an swab test at the same time for chlamydia can both tests be false negative If so what is the percentage?
Ekima
An estimate, from both tests showing negative, is less than a 2% chance you actually have the infection. The male urethral swab has a false negative rate of 15-20%. The rate of a false negative for the urine test has a false negative rate of 3-5.5%. So the chances of both being false negative, if they were done on separate days, is somewhere between 0.6% and 1.1%.
If you had them done one right after the other on the same day, the risk of a false negative result goes up, as they couldn't have been done according to instructions.

Can a female test negative for chlamydia after having it for a long time?
The test for chlamydia remains reliable even if someone has been infected for years. Unlike syphilis, long term infection doesn't give a false negative result. However, a certain percentage of people appear to clear chlamydia infection on their own, so it's possible to have chlamydia in the past but test negative now even without taking treatment.
Can you more than one false negative for chlamydia then get a positive after having PID?

Having a negative result followed by a positive normally means that you were infected with chlamydia between the first and second test.
