Usually you only go for two tests. They are blood work. One taken after 3 months from supposed infection and another taken after a total of six months from the supposed infection.
Your next test will be your final test as it is on the 6 month mark.
Why worry when you can pray?
I don't know much about the new tests. My experience is with blood tests.
What types of tests are you taking?
