Activated Coagulation Time (ACT) of Whole Blood in Normal Dogs

Abstract

The activated coagulation time (ACT) test is technically simple, inexpensive, and commercially available and provides a rapid, accurate assessment of canine whole blood clotting time. The medium ACT for 72 normal dogs ranging in age from 6 monhts to 11 years was 75 seconds, with a range of from less than 60 seconds to 125 seconds and a mean of 77.5 seconds. Significant difference in the ACT due to sex or age of the animals tested was not found.
