Albumin

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. The role of albumin is to stop fluid from leaking out of blood vessels, to nourish tissues, and carry hormones, vitamins, drugs, and ions throughout the body.

Aspartate Aminotransferase (AST)

AST is an enzyme found mostly in the liver. An AST blood test is often part of a routine blood screening to check the health of your liver. When cells that contain AST are damaged, they release the AST into your blood, from where a blood test can measure the amount of AST present.

Alanine Transaminase (ALT)

ALT is an enzyme found mostly in the liver; smaller amounts are also found in the kidneys, heart, and muscles. When the liver is damaged, ALT is released into the bloodstream, increasing the concentration that can be detected in a blood test. This often happens before more obvious symptoms of liver damage occur. The ALT test can determine if any form of liver disease is present.

Total Bilirubin (Tbili)

Bilirubin is a yellow pigment that makes up a part of bile and is formed during the breaking down of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body. Higher than usual levels of bilirubin may indicate different types of liver or bile duct problems. Sometimes, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells.
