How Accurate Is Syphilis CLIA Screening Done After 175 Days?

default
Posted on Tue, 21 Apr 2015
Question: Hello doctor,

I had unprotected sex on may 2014. I tested myself for all STI for four times upto 6 months after my unprotected sex. I want to know about my syphilis test accuracy and window period. I had syphilis CLIA screening done and I want to know how accurate is the test after 175 days of unprotected sex. I repeat that test 3 times in six months and last test was 175 days after my intercourse ( As I said earlier).
What is the difference between VDRL and CLIA test?
Which test is more accurate?
Do I need to test myself again?
Thus CLIA test is conclusive after 175 days?
Thus IBS effect CLIA test?

I forget to tell that all my STI tests comes back negative.
