Hi Sharon,

I don’t have a hard and fast rule on this but I explain to the person concerned that if there has been a significant gap between the vaccinations and the test the likelihood is the level will have dropped to an unacceptable level and they will need a booster and then another test.  I then give them the choice of having a booster prior to the test and testing 2-3 months later.  I would normally only do this if the gap is years rather than months as I frequently find the titre is good as much as two years after the vaccine.

Regards

Yvonne
