Johnes Disease Submissions Require a Veterinarian

Johnes Disease testing requirements change after the retirement of Dr. Michael Collins

  • WVDL requires a veterinarian for all Johnes Disease diagnostic testing

WVDL would like to remind clients migrating from the Johnes Testing Center that Dr. Michael Collins will be officially retired and no longer offering his services as a submitting veterinarian for testing at WVDL. He graciously agreed to be the submitting veterinarian during the one year period from the time the Johnes Testing Center officially closed its doors on September 1, 2018. After August 31st, 2019, WVDL cannot accept any samples for testing without a submitting veterinarian signature on the paperwork. Samples may be collected and shipped by the animal owners but results will be released to the submitting veterinarian.

This is not a WVDL policy but a requirement the laboratory must adhere to according to Wisconsin Veterinary Medical Examining Board as the WVDL does not fall under the legal umbrella of academic practice that is in effect at the University of Wisconsin School of Veterinary Medicine.

If you have any questions, please do not hesitate to call. We appreciate your business and look forward to continuing to work with you in the future.


WVDL-Madison Increases Disposal Charges

Beginning August 1, 2019 we will charge clients $1.50 per pound for alkaline hydrolysis tissue digestion and $6.00 per 100 pounds for rendering.  We have done our best to keep the cost of carcass disposal to our clients very low over the years.  Due to increases in cost over the last few years, we are raising the rates of our animal disposal options. 

The cost of operating our alkaline hydrolysis tissue digester is difficult to estimate.  Recently we worked with a Mechanical Engineer and the Manufacturer to calculate the cost and found that we were offering this disposal method at about a third of the cost of operation.

Disposal method Previous price / lb New price / lb
Digestion $0.50 $1.50
Rendering $0.00 $6 / 100 lbs

If you have questions about this change in disposal pricing please don’t hesitate to contact us.

WVDL to Refer All Mineral and Trace Nutrient Testing to Michigan State

WVDL to Refer All Mineral and Trace Nutrient Testing

Permanent Change to Take Effect April 1


The Chemistry and Toxicology testing section at the WVDL Madison laboratory will refer all mineral and trace nutrient testing to Michigan State University’s Veterinary Diagnostic Laboratory. This action is in response to an equipment failure and subsequent decision to not replace this equipment.  Approximately 500 tests per year at WVDL will be affected by this change.

Starting April 1st, 2019, all mineral and trace nutrient testing will be referred to MSU. Michigan State’s published turnaround time is 5 business days for this testing. Clients will be charged the published testing fees located on the MSU website in addition to the $20 referral fee routinely charged for out-sourced testing services.

We apologize for any inconveniences this may cause our clients and invite feedback at any time. If you have any questions regarding this issue please contact the WVDL and ask to speak with a staff member in our Chem/Tox Lab

The start of the Wisconsin deer hunting season back on Sept. 15 also signaled the start to the busy Chronic Wasting Disease (CWD) testing season at the Wisconsin Veterinary Diagnostic Laboratory (WVDL).  The WVDL is at the forefront of CWD testing, establishing itself as the premier lab for this testing in the country.  Nationally, 11 states (Alabama, Arkansas, Connecticut, Kansas, Kentucky, Michigan, Montana, North Carolina, Virginia, West Virginia and Wisconsin) have submitted wild animal samples to WVDL this year for CWD testing.  With just one month remaining in the calendar year, WVDL expects to test upwards of 35,000 wild animals in 2018, with the majority of these samples coming in the last few weeks.

Additionally, 15 states (Alaska, Alabama, Arkansas, Iowa, Illinois, Kansas, Kentucky, Maine, Michigan, Missouri, Montana, North Carolina, Oklahoma, Virginia and Wisconsin) submit samples from captive animals to WVDL.  Testing numbers for captive animals are expected to reach 3,500.

Recently Dan Barr, Pathology Sciences Supervisor at WVDL, talked with WKOW-TV news reporter David Johnson on the vital role the lab plays in CWD testing.  Click HERE for that complete story.

CWD is a disease known as a TSE (Transmissible Spongiform Encephalopathy) disease.  The WVDL also tests for two other TSE diseases, BSE (7,000 cattle expected to be tested in 2018) and Scrapie (2,000 goats and sheep tested in 2018).

Keith Poulsen, WVDL Interim Director

Dr. Phil Bochsler has stepped down as WVDL Director, effective immediately.   The Board of Directors of the Wisconsin Veterinary Diagnostic Laboratory would like to thank Dr. Bochsler for his years of service as the lab director.  He will return to diagnostic pathology at WVDL.

Dr. Keith Poulsen has been appointed Interim Director of WVDL until such time as a permanent Director is hired.  The national search for a permanent Director will start soon.  Dr. Poulsen has most recently held the position of Section Head of Client Services and will continue a joint appointment in Large Animal Internal Medicine at the University of Wisconsin School of Veterinary Medicine.

WVDL Testing Fees to Increase on Oct. 1

WVDL Testing Fee Increase Takes Effect Oct. 1


The Wisconsin Veterinary Diagnostic Laboratory (WVDL) will raise test fees by 4% beginning October 1.   The Board of Directors approved the increase over the summer as the lab has not had a comprehensive increase in its testing services in four years.

“Not surprisingly and likely similar to your businesses, in order to get the work done our costs of doing business are gradually rising,” said WVDL Director Dr. Phil Bochsler.  “We will continue to strive to keep costs reasonable while producing the best results and service possible.”

Our clients will see that most testing costs were increased 4% across the board, but there are exceptions.  Some tests saw prices remain unchanged or saw increases or decreases in costs that were above or below the 4% figure.

These changes in prices affect only testing services.  Supplies, shipping costs and media costs are NOT part of this price adjustment and those costs will remain unchanged.  Additionally, referral testing or outsourced testing, is not affected by WVDL price increases, since these costs are dependent upon the referral lab’s testing fees.

We appreciate you and your business and if you have any questions, please don’t hesitate to contact us.



Wisconsin Poultry Producers and Interstate Movement to Iowa

LPAI Testing for Wisconsin Poultry Producers and Interstate Movement to Iowa

Purpose: The State of Iowa requires serology and PCR testing for avian influenza prior to interstate movement from Wisconsin. WVDL is setting up special testing for Wisconsin poultry producers to facilitate this movement.

Iowa is currently requiring permits for poultry and poultry products from Wisconsin to Iowa and if there are any questions, they should contact Iowa.

Here is a link to their web site:


Test logistics at WVDL:

  1. Serology for antibody: WVDL has the NPIP-approved test for antibody (AGID). This test is performed at the Barron Laboratory ONLY, is a 24-hour test and is set up at 2pm Mon-Thurs.

a. Samples must be dropped off in Madison by 10am for same day results for movement of animals the following day (8AM) to fit the requirement of 24 hours from sampling of animals to shipment. Depending on location in Wisconsin, overnight UPS shipping may be allowed for PCR testing. This will increase time to maximum of 36 hours from sampling of birds to shipment and PRODUCERS MUST contact the Iowa State Veterinarian’s office for prior approval.  Dr. David Schmitt (515) 281-8601.

b. Each PCR test (up to 11 swabs per test) will have an expedited testing fee added.

c. Please call ahead for testing so we can be prepared to accommodate your testing needs to the best of our ability.

d. Any NPIP-approved laboratory can be used for PCR testing.  The Minnesota Veterinary Diagnostic lab is the next available option. Minnesota runs  PCR Mon-Fri and samples must arrive by 8am.

Testing supplies:
