******************************** Please remove this footer before replying.Hi JoI think the best answer to you question is... if they have produced evidence of immunity in the past, do not test them for antibodies again.(Green Book)Then you will not have the issue. It seems that the results do not have to be an IVS even if they are now doing exposure prone procedures.Do not spend money on unnecessary blood tests.If there is uncertainty about their response to primary course, then the only time that a test is reliable is one to four months after a dose of vaccine. You might want to get the option of giving this type of dose written into your PGD. otherwise you will need a patient Specific Direction for the individual, which may mean them coming back another time if you don't have a doctor on site.
If blood test is done outside of this time frame then a "low" results does not mean that they have not developed immunity in the past.A high result may just mean they have been exposed to the virus recently.. why else would the body produce the circulating antibodies months or years after vaccination?
