Both are reliable.

Hi
Thank you for query. I am Dr Bharatesh D Basti answering your query.
Welcome back to health care magic.
The tests for only HIV antibodies 1&2 is usually considered conclusive after 12 weeks.

The enhanced centaur assay also detects antibodies to O in addition to HIV 1&2 antibodies. It is further more helpful in detection. But does not mean the antibodies to HIV 1&2 test is not sensitive. Both are reliable and are conclusive after 12 weeks.
You can get back for any clarification.

Brief Answer:
Antibodies are formed latest by 12 weeks .

Detailed Answer:
Hi
Thank you for follow up query.

Conclusive means the results are final after the particular duration.
For Example ,antibodies test if found negative after 12 weeks exposure, implies that he is free from HIV from that exposure.
Antibodies take 2-6 weeks to be formed after exposure to virus.In few individuals it may take up to 12 weeks.
So conclusive after 12 weeks.
