If TB has been confirmed* in your herd, or when more than1 animal has been positive in your herd at the skin test, or more than 5 animals have been LRS at the abattoir, it may be possible to lift restrictions after two clear full herd tests in a row (RH1 and RH2), involving every animal in the herd. A Lateral Check Test (LCT) is required when a herd is at risk to disease due to its location, usually due to another herd immediately next door.

When TB is found in a herd by the disclosure of a skin test reactor or a Lesion at Routine Slaughter (LRS), an important part of the veterinary investigation is to identify where the infection may have come from. When visible signs are seen, the animal is said to have had a Lesion at Routine Slaughter or LRS. Bovine tuberculosis (TB) in domestic pets - GOV.UK Anim.

By checking APHIS on-line, by asking the vet to whom your test is allocated or by phoning your local Divisional Veterinary Office. This is to check that no infection remains and to make sure that any original cause of infection has not resulted in the infection of more animals in your herd. Tuberculous spondylitis, or "Pott disease," is a type of tuberculosis that is present in the spine. An individual animal may have missed an Annual Herd Test because it has been sold from one herd to another and may end up not tested for 15 months because of this. However, the skin test is the best test available for screening live cattle. Diagnosis of bTB in wildlife is done by testing lymph nodes and tissues with lesions for the presence of M. bovis .

For some diseases this is not a complicated matter, but for Mycobacterium bovis that infects a wide range of mammals, including humans, there is not a single test or procedure by which to reliably confirm the diagnosis in all infected and diseased animals, mostly because of the lack of sensitivity and specificity of all the currently available tests.
