HEV can be found by microscopically examining a stool sample, but this is not a reliable test, as the virus often dies when stored for a short time. Like other hepatitis viruses, HEV stimulates the body's immune system to produce a substance call...

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.A...

|
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 oxaloaceti...

A platelet count is a test to measure how many platelets you have in your blood. Platelets help the blood clot.
|
|
A platelet count is a diagnostic test that determines the number of platelets in the patient''s blood. Platelets, which are also called thrombocytes, are small disk-shaped blood cells produced in the bone marrow and involved in the process of blood...

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...

This test roughly measures the types of protein in the fluid (serum) part of a blood sample. See also:Immunoelectrophoresis - serumImmunofixation - serumSerum globulin electrophoresisLipoprotein electrophoresisA blood sample is needed.

Separation is based on differences in the charge(and sometimes size) of the molecules, which determines their rate of movement in an electric field. Serum protein electrophoresis is a screening test that measures the major blood proteins.
|
|
Serum protein electrophoresis(SPEP) is a screening test that measures the major blood proteins by separating them into five distinct fractions: albumin, alpha 1, alpha 2, beta, and gamma proteins. Protein electrophoresis can also be performed on u...

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

Albumin is a protein made by the liver. A serum albumin test measures the amount of this protein in the clear liquid portion of the blood.A blood sample is needed.
|
|
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.
|
|
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.Medical testing of alkaline phosphatase is concerned with the enzyme tha...

Bilirubin is a product that results from the breakdown of hemoglobin. Total and direct bilirubin are usually measured to screen for or to monitor liver or gallbladder problems.Total bilirubin; Unconjugated bilirubin; Indirect bilirubin; Conjugated...

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 jaundice in about 99% of newborns.

Gamma-glutamyl transpeptidase(GGT) is a test to measure the amount of the enzyme GGT in the blood.Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine(an...
