No,

Detailed Answer:
Hi,

Thanks for your query.

The test is strongly reliable after 12 weeks .

It can even show right results even after 2 weeks after the exposure but the sensitivity and the reliability is a question.

Hope, I answered your query.

Revises CDC guidlines 2014 says that it is conclusive after 45th day, if uses 4th generation combo test

Brief Answer:
false negatives still exist

Detailed Answer:
Hi,

Thanks for writing back.

The number of false negatives decrease as the duration exceeds 45 days. Hence more reliable in later days. And the false negatives fall almost to nil after 12 weeks.
