Send samples to LIC

Learn how to collect and send tissue, milk or blood samples to LIC.

Most of our animal tests are done using milk samples or tissue samples. Some can be done using blood samples.

You can easily take tissue samples yourself. Your vet will usually take the blood samples. In most cases we get milk samples from your dairy company or from herd tests.

The samples we use for animal testing are:
  • milk samples
  • tissue samples
  • blood samples.

Tests that use milk samples

We use milk samples for:

  • Johne's disease whole herd testing
  • BVD bulk milk testing
  • BVD PI Hunt
  • BVD PI Clear
  • milk pregnancy testing.

In most cases you don’t need to send the milk samples to us — we use either bulk milk samples from your dairy company or individual milk samples from herd testing. 

You may need to send us a custom sample to check the BVD status of a small number of cows in your herd. Call us on 0800 436 362 to find out how to collect and send us a custom milk sample.  

Tests that use tissue samples

We use tissue samples for:

  • DNA parentage testing
  • A2 geneotype testing
  • BVD testing.

It’s easy to take the tissue samples yourself — just follow the instructions in: 

  • Collecting tissue samples for DNA parentage testing 
  • Collecting tissue samples for A2 or BVD testing.

Tests that use blood samples

We must use blood samples for:

  • Freemartin DNA testing.

We can use blood samples for:

  • BVD testing 
  • Johne's disease testing for individual animals
  • DNA parentage testing (if you are unable to get a tissue sample).

In most cases your vet will take the blood samples using a purple top blood tube. 

For whole-herd DNA parentage testing complete, sign and send us the GeneMark Whole Herd Account Application form to set up your GeneMark account.

To DNA parentage test follow these steps. If you’re whole-herd testing you must book a testing date with our GeneMark laboratory and get your samples there by that date. Contact your local LIC rep or call GeneMark on 0800 436 362 to make a booking.

We provide a free Field Assist to help whole herd customers the first time they take samples.

There’s no need to book if you’re doing individual animal DNA parentage testing (or nominated animal DNA parentage testing for goats) — just courier us the tissue samples.

1. Order your sampling equipment

The GeneMark Allflex applicator gun and the GeneMark Allflex punch kits make DNA sampling quick, easy and hassle free.

To take tissue samples you need an applicator gun and enough punch kits to get samples from all the animals you want a DNA profile for. Each punch kit contains 10 tissue sampling units.   

You can order sampling equipment  by:

2. Sample your animals

To sample your animals follow these steps:

  • Take a new tissue sampling unit (TSU) out of the punch kit and fit it into the applicator gun.
  • Record the tag number of the animal you are sampling on the card on the front of the punch kit — be careful to match the barcode on the TSU with the barcode on the card.
  • Collect the tissue sample using the applicator gun.
  • Remove the TSU from the applicator gun and put it into a ziplock bag.  
  • When you’ve used all 10 TSUs in the punch kit remove the completed card and put it into the ziplock bag with the TSUs.
  • Use a new ziplock bag for each group of animals you sample (calves, cows, previous season’s progeny and natural mating bulls).   
  • Store the samples in the freezer if you’re not planning to send them to our laboratory immediately.

3. Courier us your samples

Courier the samples to our laboratory using the courier bag provided. You don’t need to keep the samples chilled for couriering, but make sure they get to us no later than midday on a Friday so they arrive when our laboratory is attended.

Include a completed Whole Herd Submission form or a completed Individual Animal Submission form depending on which test you are doing. Use a new submission form for each group of animals you test.

For goats, include a completed Goat Whole Herd Submission form or a completed Goat Nominated Animal Submission form depending on which test you are doing. Use a new submission form for each group of animals you test

Send the samples with the completed submission forms to:

You’ll receive a confirmation email from the lab once your samples have been received.

Track your samples in Member Services — go to My GeneMark Submissions to see the status of your tissue samples (for whole herd testing only).

4. Getting the results

Whole herd parentage test results arrive within four weeks. Individual parentage results arrive within six weeks.

We’ll email the results of the tests to you and we’ll also upload them to MINDA.

Combine A2 geneotype testing or BVD testing with DNA parentage testing

You can combine A2 geneotype testing or BVD testing with either whole herd DNA parentage testing or individual animal DNA heritage testing.

You don’t need to collect separate tissue samples if you combine the tests — just tick the appropriate box on the submission form when you send the samples to our laboratory.

Collecting tissue samples for standalone A2 geneotype or BVD testing

Collect tissue samples for standalone A2 geneotype testing and BVD testing in the same way as for DNA parentage testing.

Collecting tissue samples for DNA parentage testing

Once you’ve collected the tissue samples, complete the appropriate submission form:    

Tick the appropriate box on the submission form and courier the tissue samples with the completed form to: 

LIC Diagnostics
140 Riverlea Road
Hillcrest

Use blood samples to test for:
  • Freemartins
  • the BVD virus in calves less than 35 days old 
  • the BVD virus in older animals when you can’t take a tissue sample
  • BVD immunity in individual animals 
  • Johne's disease in individual animals to confirm you have the disease in your herd before going ahead with whole herd testing using milk samples. 

In most cases your vet will take the blood samples using a purple top blood tube. You can also call AssureQuality on 0508 001 122 to organise sampling.

Chill the blood samples if you’re not sending them immediately.  Complete the appropriate submission form: 

Tick the relevant box on the form and send the samples and the completed submission form by courier to:
