Brief Answer:
Highly sensitive

Detailed Answer:
Hi
Thank you for query.

Tridot test is used to detect antibodies to HIV 1& 2. It is a very sensitive test > 99%.

Antibodies may take 2 weeks to 3 months to be formed.

As the test is done on 81 days it is almost conclusive that you are free from HIV.

But you can repeat the test again after 3 months of exposure to allay fears totally.

All encounters are not a risk. It also depends on partner history.

You can get back for any clarification.
