DRL maintains its USDA accreditation for Johne’s disease testing

The results of the 2018 USDA laboratory proficiency tests are in and DRL have once again received full marks. We remain one of only two laboratories in the southern hemisphere, and the only laboratory in NZ, to achieve this level of accreditation from the United States Department of Agriculture (USDA) for PCR quantitation of Johne’s (MAP) shedding in individual faecal samples, in pooled faecal samples, in milk and in serum. We voluntarily undertake this independent validation every year to ensure that our diagnostic reporting is top notch!

This accreditation process involves blinded testing of proficiency panels comprising bovine faecal samples of known infection status and faecal culture titre, administered through the US National Veterinary Services Laboratory (NVSL, Ames, Iowa) as part of an ongoing JD proficiency testing panel for diagnostic laboratories. The NVSL JD proficiency panels are distributed annually to diagnostic and research laboratories both in the US and internationally and are used to accredit testing services for JD diagnostic testing in the US. DRL are a USDA Animal and Plant Health Inspection Service accredited testing laboratory for JD (organism-based methods (direct PCR and pooled PCR) and serum/milk ELISA) and have participated and passed NVSL JD proficiency panels annually since 2008.
