HI, thanks for using healthcare magic
The window period is the time between the onset of an infection and time it takes for it to show up in a test.
It varies according to the test done. The window period for the PCR is stated to be 2 to 3 weeks.
test has a window period of 3 to 6 months.
If you did the PCR DNA
test, then the window period is sufficient and the test can be considered confimed negative.
IF you did an ELISA test then you can consider repeating it at the 6 month mark to confirm that it is truly negative.
I hope this helps
