The Animal and Plant Health Agency (APHA) Rabies Laboratory at Weybridge is:

  • the UK Reference Laboratory for Rabies
  • an International Reference Laboratory for Rabies (OIE, World Animal Health Organisation)
  • an EU-approved laboratory for rabies serology
  • a UKAS accredited testing laboratory No. 1769.

Please note that we are currently unable to test any rabies FAVN submission where the samples are taken in Russia and where payment would be made from a Russian bank/credit card. Testing may still be possible depending on circumstances and how the payment is to be made. Please contact us on +44 (0)3000 600022 or for advice before sending any samples to us.

The rabies tests undertaken by APHA are accredited to ISO/IEC 17025 ensuring the highest level of quality assurance. Our highly skilled team of scientists are on hand to provide a highly competitive, quality assured, service from sample receipt to result reporting.

Available Rabies Serology tests at APHA for EU and other pet travel schemes

The Fluorescent Antibody Virus Neutralisation (FAVN) test (sometimes referred to as the RNATT) offered by APHA is an approved rabies antibody titration test for monitoring the effectiveness of vaccines for pet travel schemes. The FAVN test determines whether the animal has adequate levels of anti-rabies antibodies following vaccination. An antibody level greater than or equal to 0.5IU/ml is considered an adequate response to vaccination for the purposes of commercial and non-commercial pet travel.

Two test formats are available at APHA, both provide a result as IU/ml. Samples with a titre greater than the end point of the assay will be reported as ≥ the upper limit of the test:
