A fluorometric assay was used to determine plasma antithrombin III (AT III) activities in 15 healthy adult horses. Nearly all plasma samples had an initial value of greater than 100% thrombin inhibited, so a 1:1 dilution of the prepared samples was performed. Following dilution, the mean value of the animals was 59.17 +or- 7.4% thrombin inhibited. Mares had significantly greater AT III activity than geldings or stallions. The results of this study indicate that the horse has more AT III activity than other species (man, dog) in which AT III activity has been reported.
