Important read especially for those of us with overseas rescues
Did you know?
If we had NO Brucella canis in the UK and all 12 million dogs in the UK were UK originating dogs we would still get, on average, 120,000 false positives among those dogs if vets made all those owners test for Brucella canis on a routine screening.
That is 120,000 dogs whose owners could be told that the vet recommended euthanasia because this was an infectious zoonotic disease with no guarantee of a cure. They wouldnβt even have the disease OR ever have had the disease!!! ππππππππππππ₯°π©π©
This is because the tests used are not 100% specific. Using the APHA combined parallel testing protocol (SAT plus indirect ELISA) the combined specificity of the test is ~99%. This means that if you used the test on 100 dogs that do not have BC antibodies the test will correctly identify 99 of these as negative. it will incorrectly identify one as positive. When you scale it up, the figures are staggering!
TAKE HOME MESSAGE:
Diagnostic testing is a tool to help vets with clinical decision-making, it does NOT replace clinical decision-making. Ask better from your vets!
Youβre paying for clinical expertise in line with evidence based practice and contextualised care that puts the patient and client at the heart of clinical decision-making.
Ask them to deliver on BC diagnostic interpretation and the care management of dogs but test positive that align with the quality of clinical decision-making that they would use for other clinical scenarios within the practice.
Your vet is a highly skilled professional, they deliver as a highly skilled professional in other aspects of clinical practice, and youβre paying a lot of money for the expertise of a highly skilled professional so make sure that they are delivering on that in respect of Brucella Canis.
