Note on Nitrate/Nitrite Proficiency test:


In spring 2012, the AAVDL/AAVCT Forage Nitrate/Nitrite proficiency program was initiated. This testing program ensures that all participating veterinary diagnostic laboratories are reporting accurate forage nitrate/nitrite results. Identical aliquots of dried, milled forage material were shipped to over 20 AAVLD-accredited veterinary diagnostic laboratories. The nitrate/nitrite test results obtained by the UKVDL were in excellent accordance with the expected values, as were the majority of the laboratories (see graph below). This confirms that the UKVDL nitrate/nitrite analysis methods and results are accurate. The figure below shows the distribution of results for all of the laboratories. The UKVDL nitrate results are right in middle of the group (see arrow).
