A member asked:
Hello doc, after the last dose of pep when is a 4th generation combo test conclusive? what is the window period after the last dose of pep?
A doctor has provided 1 answer
Precise data do not exist on this. It is rare for PEP to fail, and therefore few patients have been studied and such data have not been analyzed and the exact interval cannot be known with certainty. Most experts agree on 6 weeks after the last dose of PEP, but some recommend a final test at 3 months.
