It's 4th gen. Stop worrying.
The test says it is (translated from spanish) scrutiny from antibody and antigen p24 by chemiluminiscence. It is a 4th generation isnt it?
If 4th generation. it is conclusive.
If a standard antibody test, the CDC says 3 months is conclusive. Your 11 week test will not change. However, retesting at 3 months is completely up to you. It's not absolutely necessary, just for peace of mind if you need it.
