WVDL Announces Testing Changes to CAEV & OPP ELISA Tests

Testing Days for CAEV & OPP ELISA Tests Have Changed

The Wisconsin Veterinary Diagnostic Lab (Barron location) has announced a change to the week-day testing schedule for both the Caprine Arthritis Encephalitis Virus (CAEV) ELISA and the Ovine Progressive Pneumonia (OPP) Virus ELISA tests.  Both are now run on Mondays and Thursdays.  For more information on these tests, please access the Test and Fees page on the WVDL website.


WVDL No Longer Offers Brucellosis RAP Test


Rap Test No Longer Offered

The BAPA test is now the official Brucellosis screening test used at the WVDL. The RAP test will no longer be offered. Discontinuation of the RAP at the WVDL should not pose any difficulty for our submitters. Use of the BAPA will meet all the requirements for an official Brucellosis screening test for B abortis, B suis, and B mellitensis. Please note that the BAPA test is not suitable for serologic screening for Brucella ovis or B canis. Testing for these two organisms requires alternate tests.

Brucellosis screening can be requested by using the Serology & Multiple Test Submission Form (available on the WVDL website: Mark the box selecting “Bruc/BAPA.” Additional information on the BAPA test is available on our website.

Please note that the Standard Tube Test (STT) and Standard Plate Test are (SPT) are not screening tests for Brucellosis. These tests should only be requested if they are a specified test requirement.

Please contact us if you have questions or concerns.

WVDL Awarded Full AAVLD Accreditation

WVDL Receives Full, 5-Year, All-Species AAVLD Accreditation

Quality Manager Kristin Zuzek holds up the AAVLD Accreditation Certificate recently awarded to WVDL.

Quality Manager Kristin Zuzek holds up the AAVLD Accreditation Certificate recently awarded to WVDL.

The Wisconsin Veterinary Diagnostic Laboratory was recently awarded a five-year full, all-species accreditation by the American Association of Veterinary Laboratory Diagnosticians (AAVLD).  This is the longest term of accreditation awarded by AAVLD.  AAVLD accreditation is based on internationally-recognized ISO/IEC 17025 and parts of the ISO 9000 series that are relevant to the scope of testing.  The AAVLD standard incorporates the World Organization for Animal Health (OIE) Quality Standard and Guidelines for Veterinary Laboratories.

The AAVLD accreditation process involves a detailed review of laboratory programs and includes a comprehensive on-site audit of the laboratory quality system.  The site visit team, consisting of four members of the AAVLD Accreditation Committee and auditor pool audited both the Madison and Barron laboratories in October, 2013.  The AAVLD audit focused on conformance to the WVDL Quality Manual, Quality Systems Standard Operating Procedures and the AAVLD Requirements for an Accredited Veterinary Medical Diagnostic Laboratory (Version 6.1, June 2012).

The AAVLD site visit team reviewed records, observed practices and interviewed staff with regards to  training and competency programs, equipment management, facilities, safety programs, test validation, records management, and all activities from specimen receiving through results reporting, sample retention and disposal.  In addition to interviewing laboratory staff, the AAVLD site visit team also met with members of the WVDL Board of Directors, Dr. Sherry Shaw, USDA/APHIS/VS Area Veterinarian In Charge for Wisconsin and Ms. Sandra Larson (Chairperson), Business Relations Manager, Larson Acres Inc.  According to WVDL Quality Assurance Manager, Kristin Zuzek, “AAVLD accreditation is formal recognition of laboratory competence and supports our commitment to providing services which meet or exceed the accreditation standard.”


WVDL Now Offers Nutritional Trace Element Panel

Panel includes copper, zinc, manganese, selenium and iron.

WVDL is now offering a nutritional trace element panel (the new test code is NUTRITNPNL) for copper, zinc, manganese, selenium, and iron. The cost is $30 in-state, $45 out-of- state.  Liver is the sample of choice to submit. Results will be available in about one week. If interested in only selenium, submit WHOLE blood.

It is difficult, if not impossible, to accurately interpret the concentrations of macro minerals (e.g., P) and electrolytes (e.g., Na and K) detected in liver samples.  In addition, our instrumentation for minerals/elements (ICP-MS) routinely reports a total of 16 minerals/elements as part of its normal sample run.  Many of these are irrelevant in terms of a nutritional trace element panel (e.g., Arsenic, Cadmium).  In order to streamline reporting and avoid reporting unnecessary data, WVDL is now offering a nutritional trace element panel that includes reporting for only copper, zinc, manganese, selenium, and iron.

In addition, please note that most* of the trace minerals/elements are difficult to interpret and their value uncertain when assessed by running blood or serum. Liver is the relevant sample for a panel of trace mineral/element analysis.  Please visit our Test Fee List for submission guidelines and call with any questions.

*Selenium is the one trace mineral which can, without reservation, be run and reliably interpreted from whole blood samples.  Interpretation of [Se] from serum samples can be more challenging than that from whole blood samples, as a result of variability caused by feeding organic vs inorganic selenium supplements.

WVDL No Longer Provides Testing for Antimicrobial Residue in Cattle effective 1 February 2014

Antimicrobial Residue Testing No Longer Offered at WVDL

This test, performed on bovine urine, made use of a commercially available kit called the PremiTest Antibiotic Test Kit. Veterinarians wishing to perform this test for their clients can obtain a block heater and kits from Nelson Jameson Inc of Marshfield, Wisconsin  The kits are inexpensive, and the test is easy to perform and amenable to in-clinic use.

We apologize for any difficulty this may cause. However, because the test is available as a commercial kit, veterinarians can still offer this service to their clients.

Please contact the WVDL with questions.

WVDL Price Changes for 2014

Announcement of Price Changes

Effective 1 Jan 2014 the Wisconsin Veterinary Diagnostic Laboratory will increase prices of selected tests. This decision was not made lightly but was forced upon the laboratory by rising costs, such as the cost of supplies, tests kits, and utilities. (Although the WVDL is supported by state funds, this funding only supports staff salaries. All other laboratory expenses are supported by testing fees.)

The price change does not apply across the board to all tests. Some tests were excluded for a number of reasons: prices recently raised, prices set by contract, etc. Because multiple tests are affected, it is not practical to list price changes individually in this announcement. However a list of affected prices will be available on the WVDL website. In addition, the Table of Tests and Fees on the WVDL website will display updated prices on 1 Jan 2014. ( These two resources will enable you to determine if the new prices will affect your practice and your clients.

The WVDL Board of Directors approved the price changes after weighing the increased cost to our clients against the increasing costs of performing tests. We regret the need to raise prices and did not take this step without careful consideration.

If you are interested in what tests are being increased please CLICK HERE

The WVDL will continue to provide high quality testing and outstanding customer service. Please contact us if you have questions or comments.

Introducing the Chemisty unit of WVDL

Introducing the Chemistry unit of WVDL


There is rarely a dull moment for the chemists here: a single day could involve anything from routine testing, investigative diagnostic work, instrument troubleshooting, major instrument maintenance and repairs, to exciting data manipulation and calculations! We admit that may not be everyone’s idea of an exciting day, but we love it.  And the diversity and scope of the tests we offer as well as the samples we receive keep things interesting.

When telling visitors about what we do we often say, “It’s like CSI for animals.”  That can warrant a response from any tour group: they perk up a little and lose the glazed look in their eyes. Then we have to follow with our caveat, “It’s like the lab part of CSI.”
Then we tell them we get to do the exciting, investigative side of things (e.g. detecting, confirming, and quantifying elements, drugs, pesticides, herbicides, PCBs and other toxins), but the catch is the amount of time that it takes and, often, the amount of sample required.  After all, this is chemistry, not magic!  We only ask that our clients carefully read our submission guidelines on the WVDL website and we encourage everyone to call us at any time with questions (608-262-5432 ext. 3215).
