Blood samples were collected from 150 stray dogs in New Orleans, Louisiana. Dogs were then necropsied and the pulmonary artery, heart, and vena cava were examined for the presence and number of Dirofilaria immitis (heartworm). Concurrently, a serologic test was performed on these animals' serum according to the manufacturer's recommendations. All tests and necropsy results were performed "blind". The following data were obtained: of the 60 dogs with heartworm, 48 tested positive. Of the 90 dogs without evidence of heartworm, 3 were positive.
