The Process



How do I order TSUs (Tissue sample units)?

If you need tissue sampling kits (TSUs), the PBB DNA team always have them in stock and available for immediate dispatch. We can also loan you one of our TSU applicators if you’re just getting started (at no cost)!

Hair cards also available.

Simply email to place an order.

Neogen tissue sampling

As you know, Neogen prides itself on being at the forefront of technological advances, but sometimes it’s better to stick with the tried and trusted.

Neogen strongly supports the use of the most advanced technology for tissue sample collection – Allflex Tissue Sampling Units (TSUs). These units are the only form of tissue sampling accepted by Neogen and are considered the gold standard in the industry.

Neogen’s automated sample processing equipment at their new laboratories in QLD, only caters for DNA collected with Allflex Tissue Sampling Units (TSUs).

Neogen worked closely with producers and industry over many years in transitioning sample collection from hair and blood cards to Allflex TSUs. Producers have embraced this method because samples collected with Allflex TSUs can be analysed more efficiently than other methods through Neogen’s genomic analysis equipment, enabling an earlier return of test results.


Why use TSUs from AllFlex?

· Quick and precise sample collection – samples collected in just seconds using a single-squeeze motion.

· Instant confirmation of successful on-farm sampling through visual assessment. No more guessing whether enough genetic material has been gathered!

· Clean, uncontaminated sampling – the genetic material is sealed in a specially designed preservative so samples can be stored safely before being shipped to Neogen for testing.

· Fewer sample rejections during processing

· Minimal need for retesting, as tissue samples contain a large quantity of high-quality DNA for genetic analysis yielding excellent lab results.

· Can be collected from animals as young as one-day-old


There are a few ways to order, and you can choose the best option for your business:


On their own – blank

You can order TSUs in sets of 10. They will be printed with a pre-allocated barcode number.

With your birth tags

When ordering your NAIT and matching management tags from PBB you can choose to package them with a matching TSU which will be printed with your NAIT number, Year Code and animal number.

On their own – pre printed

If you provide PBB with the NAIT number, year code and animal number, we can get your TSUs pre-printed.

Can I take a tissue sample at birth?

You sure can! However, you can take them at any time, for example you may need to meet DNA testing requirements for a sale animal.

What do I do with the TSUs once I’ve taken a sample?

  • Store the sample in the fridge, NOT the freezer.

  • Fill out the order form and email the electronic copy to  If you need help with the electronic form do not hesitate to contact PBB and ask for one of the DNA team. They will be more than willing to help.  

    Send your samples to PBB – By tracked post or courier.

    For ease of processing, where possible, it is recommended that you send your samples to us packed in the box the TSUs were provided in. For pricing and breed bundle packages please click here.
