What is coagulation test?
When you cut yourself, clotting stops the blood from becoming excessive. Your blood should not clot as it flows through your veins, though. These clots have the potential to develop and move through your bloodstream to your heart, lungs, or brain. A heart attack, stroke, or even death could result from this.
Coagulation assays assess the speed and consistency of blood clotting. Your doctor can use testing to determine your risk of excessive bleeding or the occurrence of clots (thrombosis) in one of your blood arteries.
Venous blood samples for coagulation assays should be drawn into a blue top tube containing 3.2% buffered sodium citrate to produce whole blood samples with a 9:1 blood to anticoagulant ratio.
