Calls for PT for 2018 (March and September)

Previous reports of the ICAR Proficiency Tests are available here

ICAR is pleased to announce the organization of the ICAR Proficiency Test 2018.

The participation in ICAR proficiency test will comply with analytical quality assurance requirements ISO 17025 and with the system of Certification of Quality implemented by ICAR from 2006, including a recognition of the competence of laboratories and, more widely, of analytical systems in ICAR member organisation that requires regular PT participation with international anchorage.

ICAR PT Program 2018 and administrative aspects

Administrative fees

In 2018 the administrative fees are differentiated for ICAR Member (or servicing an ICAR Member) and NON-ICAR members.

If your laboratory is servicing an ICAR member – see the ICAR member list here.

For this reason in the subscription form we are asking you to report the organization’s name that you are providing the DHI results. The annual fee for a laboratory to become ICAR associate member is 1000,00 €, you can find the form here

 

Parameter Fees

The technical sub-contractor of this proficiency testing scheme is ACTALIA who has for many years collaborated efficiently with ICAR. The ICAR PT parameters considered are: fat, protein, urea, lactose, somatic cell, beta-Hydroxybutyrate (BHB), Pregnancy Associated Glycoproteins (PAG) and Microorganism DNA PCR technique in cow milk. For fat, protein, urea, lactose, somatic cell, beta-Hydroxybutyrate (BHB), it will be possible to participate with chemical (direct) method and alternative (indirect) method.

ICAR secretariat will collect the participation forms, will send you the final report and the invoice.

ICAR PT and ACTALIA PT will be organized in parallel. If you are interested in other parameters offered by Actalia you have to subscribe the Actalia order.

The contract between ICAR and ACTALIA prescribes that for the ICAR PT parameters you will receive only that invoice from ICAR.

ACTALIA will invoice your company only for the parameters that are NOT included in ICAR PT (extra-parameters). So, to be clear, ICAR will invoice for the ICAR PT parameters and Actalia will invoice separately their extra parameters.

We believe that the ICAR PT will be more useful for your quality assurance!

A feature of the new ICAR PT report will help you track and trend your performance over time. ICAR technical staff will be there to help to interpret and support you as necessary.

  • Dispatch: by express carrier with ice in isolated boxes => arrival within 1 day (for most European countries) or up to 5 days, depending on the consignee’s country.
  • Storage in the laboratory: samples must be stored at 4°C upon arrival and should be analysed for SCC no longer than 5 days, and for chemistry no longer than 10 days, after the dispatch date.
Dates of sample dispatch 1st trial 05 March 2018
Arrival expected from 06 to 08 March 2018
2nd trial 03 September 2018

Particular cautions for international delivery

Large delays can result from missing the exact fulfilment of the custom requirements of the importing country so it is important to update Actalia-Cecalait on the local custom requirements and the latest changes. For new participants, particular attention should be paid to the first trial to check transport effectiveness and, where needed, enable possible improvement with regard to delays. The most appropriate method for sample transport and delivery will be determined.
