Advanced Animal Diagnostics (AAD) updated its QScout® Farm Lab. The on-farm, portable diagnostic analyzer is designed to read a suite of animal health tests and provide producers with results in minutes. For example, the QScout MLD (milk leukocyte differential) test accurately detects subclinical mastitis in individual quarters by analyzing ratios of white blood cell types that fight infection. To perform the QScout MLD, an easy-to-collect milk sample is transferred to an MLD test. Up to 20 individual tests can be placed into the QScout Farm Lab autoloader and left unattended during the diagnostic analysis. Full data results are downloadable from the unit or online.
