Gonorrhea, Chlamydia, and Cervical cancer are not tested using blood samples. While you may have tested negative for these tests, the doctor may want a blood sample to run different tests.
A gram stain cannot detect chlamydia. A gram stain in men that finds gram negative diplococci is considered diagnostic for gonorrhea, but it can't be used in females, and it can't prove chlamydia. A gram stain in men can be used to rule out gonorrhea and possibly diagnose "non-gonococcal urethritis" if a male has symptoms. However, although it may seem that NGU is synonymous with chlamydia, there are other possible causes.
Gram negative diplococci cause chlamydia and gonorrhea. Gram positive cause pneumonia.
A negative chlamydia test means you are not infected with the bacteria.
Chlamydia trachomatis is coccoid and gram negative.
Chlamydia is a sexually transmitted bacterial infection. It is caused by Chlamydia trachomatis, a gram-negative bacteria with a coccoid shape that is an obligate intracellular parasite. It is curable.
Both partners should be tested; you should not assume that you are negative for STDs based on your partner's test. Various situations can lead to one partner being negative and another positive. Don't take a chance.
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, 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.
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.
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.
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.
