Collecting a Tissue Sample

TISSUE SAMPLES CAN ONLY BE SUBMITTED IN SITUATIONS WHERE IT IS NOT POSSIBLE TO COLLECT AN ALTERNATE SAMPLE TYPE

 

Tissue samples not collected using a tissue sampling unit (TSU) are only taken in situations where it is not possible to collect any other form of DNA sample. Most commonly, this is when calves are born dead in herds which normally take hair samples for DNA testing.

As with semen and TSUs, it is not possible to store the surplus tissue sample for future DNA testing of the animal, and so DNA needs to be extracted and stored at the laboratory. A surcharge may apply when submitting tissue samples for DNA testing,  refer to the current fees for DNA services for further details.

 

Tissue Sampling the Ear

To collect tissue sample from the ear for DNA testing;

1. Identify the ear of the deceased animal

2. With a pair of shears, cut across the ear to remove a section from the tip, 1 inch from the end.

3. Place the piece in a zip lock bag and then within a second ziplock

4. The sample should then be placed in a freezer until frozen.

5. When shipping attach the frozen sample to a cool pack, and then mail in a suitable package, such as     a small styrofoam esky.

 

Tissue Sampling the Tail

To collect tissue sample from the tail for DNA testing;

1. If the ears of the animal are not present a sample can be taken from the tail of the animal. Identify the tail of the deceased animal.

2. With a pair of shears, cut across the tail to remove a section from the tip, 1 inch from the end.

3. Cut off any hair from the switch of the tail.

4. Place the piece in a zip lock bag and then within a second ziplock

5. The sample should then be placed in a freezer until frozen.

6. When shipping attach the frozen sample to a cool pack, and then mail in a suitable package, such as     a small styrofoam esky.
