Adjustment of partial reports in relation to the Animal Health Law (AHL)
21 March 2022
The new AHL includes a number of animal diseases that, contrary to the previous legislation, are now notifiable. Because of this, it is no longer possible to report the results of tests for these animal diseases as partial results to our customers.
Only when all tests have been completed, the results will be reported to you as a customer.
This concerns the following tests:
22EAV04 Equine Arteritis Virus PCR
22MAR01 Marteilia refringens PCR
22MPT06 Mycobact. paratuberculosis ELISA
22MPT03 Mycobacterium paratbc serology ELISA
22MPT04 Paratuberculosis PCR
22MPT01 Mycobacterium paratbc serology CBR
22PRS01 PRRSV serology ELISA
22PRS02 PRRSV PCR
22PRS03 PRRSV PCR with spike control
22QFE03 Coxiella burnetii serology ELISA
22QFE01 Coxiella burnetii serology CBR
22COV04 SARS-Cov-2 IPMA
22COV01 SARS-Cov-2 VNT
22TRI02 Tritrichomonas foetus isolation
22TEV01 Tryp.evansi (Surra) serology (CATT)
22TEV02 Tryp. evansi (Surra) smear
Test result ‘inconclusive’ or ‘-*’ expired with immediate effect
21 March 2022
At request of customers, WBVR has critically evaluated the use of an inconclusive test result with regards to the equine herpes virus (EHV) PCR, reported as ‘inconclusive’ or ‘-*’. Test results were considered to be inconclusive, when the tested samples yielded a signal, but below the threshold value of the test. After analyzing data from the past years, WBVR came to the conclusion that in the specific case of the EHV PCR, WBVR can proceed with only positive or negative test results in accordance with the ISO17025 quality system. Test results including ‘inconclusive’ or ‘-*’ will therefore no longer be reported in case of the EHV PCR.
Turnaround times of diagnostics
18 February 2022
At Wageningen Bioveterinary Research we are currently dealing with lower staffing levels due to the coronavirus. Despite the fact that we are doing everything we can to meet the standard turnaround times of our diagnostic tests, this may not be attainable in some cases. Your understanding is greatly appreciated.
If you need the results by a set time, for example because of a maximum number of days between the collection of samples and export, please contact us by telephone +31 320-238302 or via of e-mail to discuss this.
Babesia gibsoni IFAT: changes in turnaround time in 2022
13 January 2022
As announced earlier, WBVR sends samples for the Babesia gibsoni IFAT to another laboratory, until the required reagents for the test can be supplied again and WBVR will be able to perform the test itself. Due to a change in service, the laboratory concerned is able to offer the test with a shorter turnaround time, which means that the turnaround time will now be 8-12 working days (instead of 20).
News from 2021
22 December 2021: testing possible again, but longer lead time
In view of the Christmas holidays of the laboratory to which the Babesia gibsoni IFAT was outsourced by WBVR, as well as the challenges concerning the sending of samples to this laboratory, WBVR has been looking hard for a solution to continue offering the Babesia gibsoni IFAT. Not only WBVR experiences problems with the delivery of test material, other laboratories are also affected. In addition, many laboratories only offer the ELISA for Babesia gibsoni, while the IFAT is the preferred test according to the certificate of South Africa. Nevertheless, WBVR has found a laboratory that can perform this test and samples can be received by WBVR again from today. The turnaround time for the Babesia gibsoni IFAT is currently 20 working days.
2 December 2021: no more testing in 2021
In addition to the message below about test outsourcing: the performing laboratory has indicated not to perform the Babesia gibsoni IFAT between 10 December 2021 and 16 January 2022 due to the Christmas holidays. Samples submitted from today onwards will not be tested in the aforementioned period and results can therefore not be reported before 16 January 2022. Customers of already submitted samples have been informed of this development.
28 October 2021: longer turnaround time
Wageningen Bioveterinary Research is still experiencing the effects of the COVID-19 pandemic on the supply of test materials. Therefore we are forced to outsource certain tests including the Babesia gibsoni IFAT to other laboratories with a similar quality system. The turnaround time for the Babesia gibsoni IFAT has therefore been extended to 8-12 working days, with the possibility of it exceeding 12 working days in some cases. The expectation is that this outsourcing will last until at least the spring of 2022.
21 December 2021
Due to the large number of packages before the holidays and the new lockdown as a result of the corona crisis, delivery by the various transporters has been delayed. It is therefore possible that materials that you order from Wageningen Bioveterinary Research will be delivered with a delay. Please take this into account when ordering.
News from 2020
13 March 2020
The outbreak of COVID-19 continues to worsen, and this has effects on the delivery of diverse articles needed for biomedical and veterinary research.
As a result of the global spread of the coronavirus, the delivery of diverse articles needed for biomedical and veterinary research is problematic. A major share of these products is being delivered to regions with the highest level of infection in order to diagnose people and prevent the further spread of the virus. Unfortunately, this also means that other regions, such as the Netherlands, will encounter delivery problems. This includes products that are crucial to biomedical and veterinary research at Wageningen Bioveterinary Research (WBVR) because we use some of the same equipment that is used to diagnose humans.
WBVR is working on all fronts to continue its work and activities. To meet this crisis, we are in constant contact with our suppliers and we are looking for alternative solutions. In doing this, we take into account the measures announced by the Dutch government.
We want to ensure our customers that we are doing our utmost to optimally carry out any orders as soon as possible.
If you would prefer to speak to us about this, please contact Dispatching Service Unit (DSU) via mail firstname.lastname@example.org or via telephone +31 (0)320-238302.
5 March 2020
When test material is submitted, we have noticed that there is still some room for improvement in the way order forms are completed and samples labelled. Moreover, because of the more stringent quality requirements arising from ISO 17025, there are a few changes to the reporting of results.
New layout for results
As of 17 February 2020, we have been sending our results according to a new layout. This is due to the new ISO 17025 standards. From now on, the report will be called the Certificate of Analysis.
This certificate clearly indicates which data were submitted by the client.
The layout of the table of results is unchanged, but there is now explicit mention of the fact that the results apply to the sample(s) as received by WBVR.
At the bottom of the certificate, there is now a table which, for ISO 17025 accredited tests, refers to the scope of Wageningen Bioveterinary Research (scope no. L389, which can be found on the website of the Dutch Accreditation Council [RvA], covers the tests carried out that are accredited by the RvA) and explanatory notes on the conformity of these accredited tests.
Under the new ISO 17025 standard, from now on we are required to mention on the revised Certificate of Analysis that it is an amendment report. We must also mention the part of the certificate in which the change has been made compared with the previous certificate. Additionally, we must indicate whether the change was made at the client’s request, or was made on the basis of a check by Wageningen Bioveterinary Research.
This requirement means that the person reading the certificate can tell which changes, if any, have been made compared with a previous certificate. It is therefore very important that all the information provided on the order form is accurate. Whilst it is still possible to subsequently change this information, this will be visible on the Certificate of Analysis.
Submitting test material for CEM diagnostics
A number of things are very important to bear in mind when submitting test material for CEM testing.
a. For example, swabs must be used to take samples of the material, and these swabs must be sent in an Amies medium (medium with activated carbon). These swabs have an expiry date. If this has elapsed when they arrive at the lab, the swabs cannot be used for testing.
b. Nor will swabs be acceptable for testing if they have not been transported in a refrigerated environment (4-10 oC) after the sample was taken and have not arrived within at WBVR within 36 hours of the sample being taken.
c. The sampling location is very important for these swabs. The sampling location must be mentioned on both the order form and the swab. Otherwise, it must be clear what the connection is between the swab and the sample, as described on the order form.
Completing order forms
We frequently still receive order forms completed by hand, despite the option of completing the order form digitally. It is not a problem to complete the form by hand, as long as the handwriting is clearly legible. If the completed forms are hard to decipher, this can result in incorrect information being put on the Certificate of Analysis.
This information can be amended, but this will be mentioned on the Certificate of Analysis. To avoid this, it is therefore very important that the order form is completed correctly and legibly.
3 March 2020
Large sections of the new Official Controls Regulation (OCR, EU 2017/625) entered into force on 14 December last. This Regulation replaces a lot of old European legislation, and brings together everything to do with official controls carried out by, or on behalf of the competent bodies. This regulation covers a lot of areas, such as food safety, animal feeds and genetically modified organisms, animal health, animal welfare and, eventually, organisms harmful to plants.
The OCR requires all member states to appoint national reference laboratories (NRL), at least if a European reference laboratory has also been designated. In the sphere of animal health, WBVR has been appointed as the NRL for a large number of animal diseases. The most recent updated list can be found in Staatscourant (Official Gazette) 69789 dated 23 December 2019. The OCR also stipulates requirements for laboratories which perform tests as part of the official controls. The applicable standard is ISO 17025 accreditation for the tests used. At present, WBVR has more than 60 accredited tests, and is working to add to this number.
Laboratory results of accredited tests by WBVR are therefore always accepted for the purposes of official controls and, for example, export diagnostics.
News from 2018
Wageningen Bioveterinary Research would like to inform you that as of 1 May 2018, our laboratory will no longer offer Mycobacterium (para)tuberculosis ELISA assays.
The Mycobacterium tuberculosis ELISA bovis (article number MTU01), Mycobacterium tuberculosis ELISA avium/para (MTU04), Mycobacterium tuberculosis ELISA MPB70 (MTU05) and the Mycobacterium paratuberculosis ELISA (MPT06) assays will not be carried out after this date due to the fact that the materials on which the assays are based are no longer available. Because of our current high quality criteria, we have decided to discontinue the tests.
Our laboratory is working on the development of animal species-specific alternatives and we will keep you informed of any news in this area.
