With the standard blood test (i.e. antigen-antibody test -- AgAb, combo, 4th generation), it's 6 weeks for sure. Older tests took longer, and for various reasons some health agencies and physicians have not changed their previous advice. And anybody can post anything they want online. But a negative AgAb test 6 weeks after the last possible exposure for sure is conclusive.
