 |
The prothrombin time test belongs to a group of blood tests that assess the clotting ability of blood. The test is also known as the pro time or PT test.The PT test is used to monitor patients taking certain medications as well as to help diagnose...

These are primary hemostasis, which is the interaction of the injured blood vessel and platelets; secondary hemostasis, which is referred to historically as the blood coagulation process; and tertiary hemostasis, which is the process of fibrinolys...

Fibrin degradation products(FDPs) are the substances left behind when clots dissolve in the blood. This article discusses the blood test to measure these products.FDPs; FSPs; Fibrin split products; Fibrin breakdown products.Blood is typically draw...
|
|
The FDP assay measures amounts of the fibrin and fibrinogen split products in the blood and directly indicates the level of activity of the fibrinolytic system. High levels of FDP will indicate increased fibrinolysis.

BUN stands for blood urea nitrogen. Urea nitrogen is what forms when protein breaks down.A test can be done to measure the amount of urea nitrogen in the blood.Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand.
|
|
The blood urea nitrogen(BUN) test measures the level of urea nitrogen in a sample of the patient''s blood. Urea is a substance that is formed in the liver when the body breaks down protein.

The process of transferring whole blood or blood components from one person(donor) to another(recipient).Transfusions are given to restore lost blood, to improve clotting time, and to improve the ability of the blood to deliver oxygen to the body''...
|
