Information about the ICAR Proficiency Test

Information and instructions about the ICAR PT Programme 2016 and the new administrative aspects

The technical sub contractor of this proficiency testing scheme is ACTALIA who have for many years collaborated efficiently with ICAR.

The ICAR PT parameters considered are: fat, protein, urea, somatic cell and lactose in cow milk.

From this year it will be possible to participate with reference and alternative method in the ICAR PT.

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

As in the previous years the ICAR PT and ACTALIA PT will be organized in parallel. Thanks to the kind and fruitful collaboration with ACTALIA we know that you have already subscribed the ACTALIA participation. In the that case, please simply sign the ICAR PT Participation form available here and send back to pt@icar.org.

If you have already submitted the information to Actalia If ICAR PT information has not been submitted already or participate in alternative methods
Simply sign the form available here and return it to pt@icar.org, no need to fill in the form again Please fill the ICAR Participation form with all the required information

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.

You will receive a revamped ICAR PT report in 2016 which we believe 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.

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.
