|
Hepatitis C should be suspected if a patient develops jaundice and reports recent contact with the blood of a person who may have been infected. There is a blood test to detect HCV IgG antibody, a substance that the body makes to combat HCV. Care ...

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...

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...

ESR stands for erythrocyte sedimentation rate. It is a test that indirectly measures how much inflammation is in the body. However, it rarely leads directly to a specific diagnosis.
|
|
The sedimentation rate test, also called the erythrocyte sedimentation rate (ESR) or sed rate test, measures the speed at which the red blood cells (erythrocytes or RBCs) separate from the liquid part of the blood (plasma) and settle to the bottom...
|
|
The erythrocyte sedimentation rate (ESR), or sedimentation rate (sed rate), is a measure of the settling of red blood cells in a tube of blood during one hour. The rate is an indication of inflammation and increases in many diseases.

Bilirubin is a yellowish pigment found in bile, a fluid produced by the liver. This article discusses the laboratory test done to measure bilirubin in the blood. Total and direct bilirubin are usually measured to screen for or to monitor liver or ...

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...

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.
|
|
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...

|
Alkaline phosphatase (ALP) is a protein found in all body tissues. Tissues with particularly high amounts of ALP include the liver, bile ducts, and bone. A blood test can be done to measure the level of ALP. See also: ALP isoenzyme test
|
|
Alkaline phosphatase is an enzyme found throughout the body. Like all enzymes, it is needed, in small amounts, to trigger specific chemical reactions. When it is present in large amounts, it may signify bone or liver disease or a tumor.
|
|
Gamma-glutamyl transpeptidase (GGT) is a test to measure the amount of the enzyme GGT in the blood.
