So on December 27th (4 days after the end of the clarithromycin
antibiotics) I used
a reputed mail tester in Japan for
a variety of STDs (providing samples of blood, urine, and throat sample obtained from gargling a solution they had sent). I was negative for everything (HIV, Hep, Syphilis, Gonorrhea, Chlamydia from the urine test, etc.), but tested positive for throat chlamydia! I'm very surprised by that.
