Most (almost all) people will test positive after the 3 - 6 weeks window period with the new tests now in use. However, as there is always a very very small change that a person had not converted by the time of the initial test, and as different tests with different sensitivities are used, we recommend that a repeat Elisa is done 3 - 6 months later. Almost a belt and braces approach. On the other hand, if the PCR was negative at 3 - 6 weeks one won't worry about a repeat Elisa 3 - 6 months later.
