Our Liver Function Screening test basically consists of liver enzymes Alanine amino transferase (ALT/SGPT), Aspartate amino transferase (AST/SGOT), gamma Glutamyl transferase (GGT), and Alkaline phosphatase (ALP) assays. Others are Total Protein, Albumin, Globulin, and Bilirubin (Total and Direct), as well as Hepatitis B surface antigen (HBsAg) and Hepatitis C antibody (HCV) screening. To perform this test you will need to visit your laboratory of choice for the collection of a blood sample.
The liver is a large organ located in the right side of the mid-back. It produces enzymes, clotting factors, and bile; detoxifies the body of harmful compounds; stores vitamins and minerals; and stores and metabolizes glycogen for energy. Because of its intimate connection with so many different bodily processes, the liver is subject to damage from several fronts. Alcohol and pharmaceutical drugs may cause liver damage, as may infections and bile duct obstructions. Liver damage may cause a variety of symptoms. Jaundice, a yellowing of the eyes and skin, is a common symptom. It is caused by the inability of the liver to help in the excretion of bilirubin.
The Liver Function Blood Tests help assess liver functioning by measuring the levels of various substances produced by the liver. Tests performed as part of the Profile Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP), Gamma-glutamyl transferase (GGT), Protein (Total, Albumin and Globulin) and Bilirubin (Total and Conjugated).
Also included to this profile testing is Hepatitis screening (HBsAg and HCV). Hepatitis is a common viral infection affecting the liver, and with a high prevalence in our society.
NOTE: Certain medications that you may be currently taking may influence the outcome of the test.
