Tissue Sampling Tag

Are you looking for a quick and easy DNA sampling method that is reliable, easy to transport, user-friendly and efficient to process at the lab?

Allflex Tissue Sampling Tags (TST) provide all of this and much more. These units take an ear punch while tagging the animal which can replace tail hair, blood, semen or other sample types used for DNA.

TST’s can be used on cattle, game, swine and sheep.

Why TST?

  • Fast, high performance sample collection. Samples can be collected in seconds with minimal animal restraint. A single-squeeze motion collects a sample with minimum distress to the animal.
  • Clean, uncontaminated sampling. The genetic material is sealed in a specially designed preservative.
  • Minimise retesting. Tissue samples contain a large quantity of high quality DNA for genetic analysis, yielding excellent lab results.
  • Sample integrity. The TST is fully sealed and positively identified with both a number on the tube, needle as well as on the tag itself.

TST can also be used for serology testing of BVD.


The following laboratories are currently accepting TSU for animal health diagnostics and genomic testing.
