Activated Clotting Time Tubes
NOTE: THE FORMULATION HAS CHANGED FROM DIATOMACEOUS EARTH TO KAOLIN. THIS HAS NO EFFECT ON TUBE EFFICACY.
For Veterinary Use Only
The activated clotting time (ACT) is commonly used in veterinary medicine as an assessment of dysfunction within the intrinsic clotting cascade.1 The ACT can be used on-site to quickly evaluate and diagnose secondary hemostasis from a myriad of conditions such as rodenticide toxicosis and other disorders characterized by a decrease in clotting factors.
Haematologic Technologies SCAT-ACT tube draws 2 mL of blood into 12 milligrams of Kaolin (6 milligrams per mL blood).
Normal Clotting Values*:
Dogs < 120 seconds
Cats < 100 seconds
Cow < 145 seconds
Horse < 45 seconds
* The above values are taken from the literature from use with tubes of a different brand of tube, and should only be used as a guideline.
FOR VETERINARY USE ONLY!
Tubes are non-sterile. We recommend phlebotomy be done with a catheter of at least five inches in length, which is equipped with a multi-sample luer adapter (MSLA).
SCAT-ACT tubes have not been validated in any controlled animal studies, and Haematologic Technologies makes no claims of performance or suitability as a screening test for coagulopathy. The responsibility for achieving accurate and clinically useful results with SCAT-ACT tubes rests solely with the Veterinarian and/or individual performing the test. Good laboratory practice dictates that each clinic should establish its own reference values by running 5 to 10 known normal animals.
Haematologic Technologies, Inc. is NOT responsible for any injuries or illness that may occur as a result from the use of these tubes.
