TB Testing

We have dedicated TB Testers who, along with our vets, perform both Government and Private tuberculosis testing for both bovines and non-bovine animals.

We are also qualified for the investigations of brucellosis and anthrax enquiries.

Private TB Blood Interferon-gamma testing (IFNG)

We are one of only a handful of practices in the UK able to offer this service.

Testing is very time sensitive. Tests must be arranged at least 1 week in advance as permission needs to be granted by the Animal and Plant Health Agency (APHA). We are also only able to collect the blood sample on a Wednesday due to the testing schedule for IFNG at the APHA dedicated laboratory.

Cattle which are eligible for private IFNG testing include the following:-

  • Supplementary pre- or post-movement testing of pedigree animals that are not subject to, or have passed, a compulsory skin test.
  • More sensitive TB screening of animals joining high-value herds, including pedigree bulls entering semen collection centres.
  • As a marketing tool to add value to herd/animals intended for sale.
  • Ad hoc testing following a negative routine or tracing skin test.
  • Rapid retesting of inconclusive skin test reactors where no government-funded IFNG blood test is planned.

Cattle which are NOT eligible for private IFNG testing include the following:

  • Cattle from herds under TB restriction and undergoing government IFNG testing.
  • Skin test-positive (reactor) and other cattle awaiting slaughter for TB control purposes.
  • Animals in Scotland, Wales or Northern Ireland at the time of testing.
  • Herds under restrictions for overdue tuberculin skin tests.
  • Cattle that are under six months of age.

For more information on INFG testing, read through APHA’s website.
