This will be my final answer. Your paranoia is leading you to ask irrelevant questions. When the two test results are considered together there there is no chance you acquired syphilis from the encounter you have described.

Great. Thanks for humouring me. I guess one of the issues in my head is there are so many different statements out there about the window period. Three months is commonly mentioned.
1)Do you have a percentage for how relaible my EIA & VDRL tests are?
2) Which test is themost accurate?
These are my final two questions. Thanks for your kind help.
1. There are concerns about azithromycin for syphilis however this is irrelevant to you. Your blood tests prove that you did not get syphilis. If you had, AND you failed therapy (both of which are unlikely) your test would have been positve.
2. Darkfield microscopes are not widely available (they are different from more typical, light microscopes) and relatively few people know how to do the test well. Again, believe your test results.
You need to put your syphilis fears aside. To continue to worry makes no sense whatsoever. EWH
Thanks for taking the time to provide such a comprehensive answer. I have a couple more questions arising from your answers:
1) I have heard that azithromycin is far from a sure thing when used for syphilis. If that is the case, is it not likely that it may have failed to clear it up and invalidated the tests done for a few weeks afterward?
2) Is a dark field microscopy really that hard to do. She (the Dr) said that the sore didn't have enough substance to it to test properly - should I insist it does get done for my peace of mind?
Thank you again.
Welcome to our Forum. Your risk of syphilis from any single encounter is low. In New Zealand syphilis is rare and only about 20% of syphilis in New Zealand occurs in women with most infections occurring in men who have sex with other men. The lesions you describe do not sound like syphilis. Finally, had you been exposed to syphilis, it is highly likely that the azithromycin you took would have prevented syphilis for occurring. Finally, your blood tests at 18, 45, and 52 days rule out the possiblity of syphilis. Thus, putting all of these together, I can assure you that the lesion you noticed was not syphilis.
In answer to your specific questions:
1) What was my risk of contracting syphilis from unprotected oral and protected vaginal?
Low, not only is it unlikely your partner had syphilis but the risk of syphilis from either protected genital or unprotected oral sex is virtually zero.
2) Does my sore sound like Syphilis to you?
Not at all.
3) Is my testing regime reliable?
Yes, it proves you did/do not have syphilis.
4) Would taking 1g azithromycin at 32 days post exposure affect the accuracy of my syphilis test at 52 days?
The azithro would prevent syphilis, had you been exposed.
5) Is getting a primary chancre at 7 weeks common?
No, it is nearly unheard of.
6) If it was a primary chancre, would this not mean the tests would take longer to become accurate.
It was not syphilis and had it been, your test would have been positive.
7) Are further tests warranted? .
No, you need to stop worrying and move on.
Take care. EWH
