Help interpreting chlamydia test result

I recently tested positive for Chlamydia (urine test).  I am a adult male, and had typical symptoms 11 days following unprotected vaginal intercourse with female A.  She was also menstruating at the time.  I was treated and the symptoms have since gone away.  I contacted female A and urged her to get tested as well.  She claims to have had no other sexual intercourse, at least in the past several years.  Still, she went to be tested.  She had a vaginal swab taken for analysis, as well as a visual check on the internal portion of her vagina.  About 6 days later, the lab results were in, and the doctor informed her that she did not have Chlamydia.  She showed me the lab results given to her from the doctor.  This is the part that confused me.  The lab result doesn't specifically say “negative for Chlamydia,” and I do not understand how to read the results.  Can a doctor please help me understand the lab results?  I am typing the results, exactly as I am reading them from a paper lab result sheet.

Welcome to the Forum.  I am afraid that your partner's doctor has not treated her in recommended fashion.  Any person who has recently (30 days) had sex with an infected partner (you) should be treated for possible infection, no matter what the examination or test results say.  In the case of the lab results you mention, there is no mention whatsoever that you partner has been tested for chlamydia.

My advice- your partner needs to be treated for chlamydial infection.  Her past sexual history makes no difference.  You should not have sex with her until each of you have been treated.

I hope this information is helpful.  EWH

What is the purpose of a gram stain test?  Is this not the right test to determine if a person has /does not have chlamydia?

The Gram stain helps to make a rapid diagnosis but it is not specific for chlamydia.  Some patients with chlamydia have negative gram stains and only about 40% of persons with gram stains suggestive of chalmydial infection turn out to have chlamydial infection (the others have a variety of other things).  

As I said, your partner was not treated in the manner recommended by the CDC, the World helth Organization and by nearly every professional organization.  EWH
