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.
