Chlamydia and Gororrhea (urine sample) and Syphilis (blood test) at the Provincial STI Clinic in
Vancouver BC. Canada. (I mention this as you would likely have familiarity with the testing methods there with your close proximity in Washington State)
I just got the results: all tests are negative - which is what I wanted to hear.
As a backup plan, my family MD has provided me with one gram of Azithromycin and 400 mg of Cefixime - which i am reluctant to take unnecessarily.
