Yes, if you caught it in the interim or if there was an error with one or both of the tests.
Yes, it is very possible. Many people can carry a bacteria or virus, then transfer it to another person (chlamydia and meningitis are good examples), and it is often that the second person gets the disease, without the first person ever being aware of their dangerous status.
A negative chlamydia test means you are not infected with the bacteria.
If you took an adequate dose of ciprofloxacin to cure chlamydia, the chlamydia test should be negative as long as you didn't get tested too soon after treatment.
There are a few possible explanations. The most likely is that you contracted chlamydia within those three months. Another possibility is that you got the first test so soon after infection that it could not yet be detected. A false negative or false positive test is another possible explanation.
The chances of a false negative chlamydia test result with the newest test kits may be as high as 10%. The chances of two false negative results are 1%, and of three are one in one thousand. Having a negative result followed by a positive normally means that you were infected with chlamydia between the first and second test.
A chlamydia culture is a particular type of chlamydia test that tries to grow the bacteria from a sample of body fluid. It is very difficult to do correctly, and so is not a very reliable test. A positive chlamydia culture can be believed, but there are many false negative chlamydia cultures. Talk with your health care provider about the right chlamydia test for your situation.
Yes
A pap smear does not detect chlamydia. A pap smear can not detect chlamydia, and a negative Pap smear does not indicate that you don't have chlamydia. So, yes, it's possible to have a Pap test for four years and not know you have chlamydia if your health care provider didn't do a specific test for chlamydia. Did your health care provider actually test for chlamydia in the prior four years? First check with your health care provider, and then you can try to figure out how you might have contracted it, if in fact you had a negative test as soon as a year ago.
Urinating within hours of the urine or swab test, not using the first urine that comes out, or inadequate swabbing can all cause a false negative chlamydia test. In addition, testing too soon after exposure, or recent exposure to partially effective antibiotics could cause a negative test that would be positive within a couple of more weeks.
Chlamydia doesn't cause a late period or change your menstrual cycle. If your period is late, take a pregnancy test.
There are a number of situations that could cause a positive chlamydia test followed by a negative test:Post-treatmentImperfect testUrinating within a short time before that negative second test was collectedLab errorAlso, a certain percentage of patients clear chlamydia without treatment. The infection may still have done damage before the immune system cleared the infection, though.I'm sure there are other possibilities, but those are the ones that jump to mind.
No , but a negative test can be a false positive .
