Technical Abstract: Experience has shown that, for a number of reasons, a diagnosis of porcine reproductive and respiratory syndrome (PRRS) is sometimes difficult. In this review we discuss: 1) field observations and laboratory tests that are useful in arriving at a definitive diagnosis; 2) the impact of so-called atypical PRRS on diagnostic procedures in North America; 3) the means by which diagnostic problems can often be circumvented by appropriate sample selection; and 4) methods used for presumptive identification of PRRS virus strains.
