Produced by the liver or blood vessels, the coagulation factors are continuously released into the bloodstream. When an injury occurs these factors are activated in a step by step process called the coagulation cascade. Complete blood count.

If the blood must be drawn through an indwelling catheter, possible heparin contamination and specimen dilution should be considered. CoaguChek ® is a portable coagulometer that provides INR results in less than one minute from a single drop of blood taken from the tip of the finger. CoaguChek ® has demonstrated accuracy and is recognized internationally as a reliable means of monitoring INR. If drawn through an indwelling catheter, flush with 5 mL of saline and discard the first 5 mL of blood collected before collecting the specimen for coagulation testing.

The test may be ordered for any number of conditions where a doctor has concerns about the patient’s ability to form blood clots. How to perform a PT test using the KC1 semi-automated coagulation analyzer. Coagulation is the final and most definitive process of hemostasis and allows for the creation of a highly stable, long-lived clot. The entire process of coagulation is directed toward creating fibrin, a highly fibrous protein that essentially forms a mesh, entrapping blood cells and platelets, creating an unyielding gel-like substance that can prevent blood loss from large tears in the In conclusion, a programmed centrifugal analyzer is a safe, efficient, and flexible way of automating routine coagulation tests. It widens the reportoire of tests performed in the Hemostasis laboratory by using a machine capable of being used in other areas of pathology. PMID: 3348169 [Indexed for MEDLINE] MeSH terms.
