Monthly Report: Surveillance Project SB4008 IFNg (TC0651 and TC0751) & Antibody (TC0077) tests for bovine tuberculosis-September 2025
Source: environment.data.gov.uk (2026-01-14)

Interferon-Gamma Testing for Bovine Tuberculosis - Monthly Reports from January 2025. These monthly reports summarise the gamma tests completed / reported during that calendar month. The report also summarises tests for the whole calendar year to the end of the current month. While all effort is made to ensure the accuracy of the test data, small errors can occur and later corrected in subsequent reports.
Tests are listed by country (England, Wales, Scotland) and by Animal Health Office (AHDO) and the reason for the test. Reports contain test data for the month, the calendar year to date and total tests since rollout (23rd Oct 2006).
Please note: this dataset consists of 12 monthly reports. Data for this report was compiled from field staff inputs and laboratory test information. Subsequent minor data amendments may have been made after the report was originally compiled, and these corrections would appear in the following month’s report. Each report was checked and deemed correct at the time of release.

Monthly Report: Surveillance Project SB4008 IFNg (TC0651 and TC0751) &
Antibody (TC0077) tests for bovine tuberculosis for September 2025
• “Samples” refers to an individual tube of blood taken from an individual animal which is subsequently submitted for testing. It is generally
assumed that the number of samples and the number of animals are analogous as any duplicate sample blood tube from the same animal will not
be tested. However, minor discrepancies may occur where the same animal is tested more than once due to a request for a resample or the
animal is tested twice under different categories (for example, as a PAR-RAPID and then as part of a PAR-HERD-S).
• "Submissions” refers to an individual batch or set of samples received for testing. Submissions may comprise 1 or more samples (for example,
if an entire herd is being tested it is usually sent as 1 submission). It is generally assumed that the number of submissions and the number of
herds are analogous.
• Retests are samples where the first ELISA assay fails and the same sample is retested on a new ELISA plate. Each sample can be retested only
once. A retest is not a reportable test outcome.
• Resamples are where a sample has been retested and failed a second time, so that the lab requests a new sample. This is a reportable test
outcome.
• Rejects are samples that are not tested by the lab for one of the following reasons: blood collected into wrong type of vacutainer, samples that
have not been maintained at the appropriate temperature range (22±5C), unlabelled samples, broken or cracked tubes, blood that is extensively
clotted (small clots are OK), samples received after 4pm on the day after sample collection. Such samples are reported separately in the tables
and in figure 5.
• POS (pokeweed mitogen) is a sample positive control reagent which provides a measure of the quality/viability of the blood sample. A POS fail
(< 0.45 optical density reading) may indicate compromised blood quality as a result of collection/transportation conditions or due the animal
having an unusually low/suppressed cellular immune response.
• NEG (no-antigen control) is a sample negative control which provides a measure of the background antigen-independent IFN- responses. A
NEG fail (> 0.3 optical density reading) may indicate a laboratory procedures problem (normally resolved during re-test) or that an animal has
unusually high background levels of IFN-g.
