This paper will discuss the ever-changing world of diagnostics in dairy veterinary practice and point out a few things that veterinarians should know concerning test selection and test type. It will be focused primarily on diagnostics for herd-level problems of dairy cattle and will touch on mastitis, abortion and BVD. In addition, some time will be allocated to a brief overview on PCR and advances in culturing. The remaining content of this paper will focus on diagnostic sampling strategies for common dairy herd problems, some disease investigation, routine sampling and interpretation of results.
