3rd generation test


I was wondering about the Canadian standard for tests.
I had an HIV test done in Halifax 9.5 weeks after exposure which was reported negative. I don't know if a Western Blot was required to rule out the infection or not.
My question is, does anywhere in Canada still use a 2nd generation test, or is it required for ALL health care facilities to use a 3rd generation test now?
I had many symptoms, which all left after 2 weeks but the swollen lymph node remains. I am going back to test at 12 weeks.
Thank you.


Hi there & thanks for your question. 
No, to the best of my knowledge, nowhere in Canada still uses a 2nd Generation test.
In Canada, 3rd Generation Tests are considered standard and in some places, 4th Generation (DUO/Combo) tests are now available. 
A negative test at 9.5 weeks post exposure is a very good indication of your status and I would expect your results at 12 weeks to be the same. 
If you have swollen lymph nodes, I would suggest working with a medical professional to figure out what the cause is. Only a medical professional can assess whether or not your lymph nodes are swollen so please do not self diagnose this. 
I hope I helped to answer your questions & I apologize for the delay in response. We have been updating our website recently and so have fallen a little bit behind in answering questions.
Please do not hesitate to call, email or comment on this response if you have any other questions or concerns.
All the best,
