Urine drug screening, or toxicological screening, is a process of chemical analysis designed to test patients for drug abuse, or to insure that a patient is substance-free before undergoing a medical procedure.
|
|
Because of the growing use of illicit drugs and the abuse of prescription drugs and alcohol in modern society, an extensive program of worksite drug testing has developed. Workers who abuse drugs are much more likely to injure themselves and put f...

Gamma-glutamyl transpeptidase (GGT) is a test to measure the amount of the enzyme GGT in the blood.
|
|
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...

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.

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.
