Partial thromboplastin time (PTT) is a blood test that looks at how long it takes for blood to clot. It can help tell if you have bleeding or clotting problems.
|
|
The partial thromboplastin time (PTT) test is a blood test that is done to investigate bleeding disorders and to monitor patients taking an anticlotting drug (heparin).

Fibrinogen is a protein produced by the liver. This protein helps stop bleeding by helping blood clots to form. A blood test can be done to tell how much fibrinogen you have in the blood.
|
|
Fibrinogen (Factor I) is a protein that originates in the liver. It is converted to fibrin during the blood-clotting process (coagulation).
|
|
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.

When injury occurs to a blood vessel wall, thrombin (a coagulation enzyme) is formed in the first stage of a complicated series of steps called the coagulation cascade. In the second phase, fibrinogen, a coagulation protein made by the liver , is ...

AST (aspartate aminotransferase) is an enzyme found in high amounts in heart muscle and liver and skeletal muscle cells. It is also found in lesser amounts in other tissues. This article discusses the test to measure the amount of AST in the blood.
|
|
The Aspartate aminotransferase test measures levels of AST, an enzyme released into the blood when certain organs or tissues, particularly the liver and heart, are injured. Aspartate aminotransferase (AST) is also known as serum glutamic oxaloacet...

|
A bilirubin test is a diagnostic blood test performed to measure levels of bile pigment in an individual's blood serum and to help evaluate liver function.

Monitors the liver function of newborns. The bilirubin test is a blood test to monitor the liver function of newborns. The rapid destruction of red blood cells after birth produces more bilirubin than the infant's liver can handle, causing some ja...

Common tests that are used to evaluate liver function include: Albumin; Alpha-1 antitrypsin; ALP; ALT; AST; Gamma-glutamyl transpeptidase (GGT; Prothrombin time; Serum bilirubin; Urine bilirubin. Please see individual tests for details on how each...

Liver function tests, or LFTs, include tests for bilirubin, a breakdown product of hemoglobin, and ammonia, a protein byproduct that is normally converted into urea by the liver before being excreted by the kidneys. LFTs also commonly include test...

Liver function tests, or LFTs, include tests that are routinely measured in all clinical laboratories. LFTs include bilirubin, a compound formed by the breakdown of hemoglobin; ammonia, a breakdown product of protein that is normally converted int...

Alanine transaminase (ALT) is an enzyme found in the highest amounts in the liver. Injury to the liver results in release of the substance into the blood. This article discusses the test to measure the amount of ALT in the blood.

Prothrombin time (PT) is a blood test that measures the time it takes for the liquid portion (plasma) of your blood to clot. See also: Partial thromboplastin time (PTT)
|
|
|
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.
|

Hemostasis has been described as "a process by which the body spontaneously stops bleeding and maintains blood in the fluid state within the vascular compartment." There are at least four major systems that are involved in this complex process: th...

One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (...

A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet co...
