David,

That would have been the ELISA test for antibody. The virus neutralisation test result will be another 2 or 3 days.

If the blood sample is taken within the first 5 days of infection the ELISA test will always be negative. They should also be running a virus neutralisation test to try to detect virus which can be in the blood for up to 5 days.

However DEFRA seem to have abandoned testing for virus and run the virus neutralisation test the other way round to do a second test for antibody.

There is therefore good reason to expect the second test will also be negative.
It could be they don't have the skilled technicians to run the test the right way round or it could be the tests have been rigged to maintain "disease free status".

As I said "Fair enough" but the consequences will always be a catastrophic epidemic now and again.

Bill.
