Liver Function Blood Test Results That Show An Elevated or Abnormal

Elevated Liver function Test

Nowadays a simple blood test can be used to diagnose the presence of many sexually-transmitted diseases. Although there are other types of testing used, such as swabbing, urine samples and biopsies,
STD Blood Testing is arguably one of the most effective means of testing for sexually-transmitted diseases.

Usually a laboratory technician, phlebotomist or nurse will draw the blood sample to be used for the test. The blood test will consist of analyzing this small sample of blood. In reality it is the serum or plasma that is subjected to analysis, and not actual blood cells.

A Blood Test May Uncover Potential Problems with the Liver: There are several tests which measure enzymes in the blood and indicate potential problems; they include ALT, AST, ALP, GGT and LDH. The PT or Prothrombin time test measures how long it takes the blood to clot. Increased clotting time may indicate there is liver damage. Albumin and total protein is a test for the levels of albumin which is a protein produced by the liver. The liver produces proteins that aide the body in fighting infection. If the levels are lower than normal it can indicate liver disease or damage. Medication can help to improve clotting.

Elevated Enzymes Can Indicate Liver Damage: There are several tests which can indicate a problem in the liver based on elevated enzymes in the blood. Alanine transaminase or ALT is an enzyme that is mainly found in liver cells and it aides the body in metabolizing protein. The levels of ALT are usually low, but when the liver is damaged it releases more ALT into the blood and raises the levels. Aspartate transaminase or AST is an enzyme that helps in the metabolism of the amino acid alanine. AST is usually found in high concentrations in the liver cells and an increase could indicate liver disease or liver damage. Alkaline phosphatase or ALP is an enzyme that is normally found in high concentrations in the bile ducts, in the liver and also in other tissue. High levels of ALP could also indicate liver disease or damage. Other enzymes that could be tested for high levels in the plasma and indicate liver disease or damage could include Gamma-glutamytransferase or GGT and Lactate dehydrogenase or LDH.

Testing is Necessary If Blood is Present: Anytime a person is vomiting blood or has a bloody or black bowel movement it is time to consult a doctor because it could be an indication of liver disease or damage. Other symptoms may include jaundice, dark urine, nausea, swelling or pain in the belly, fatigue or loss of stamina. Exposure to hepatitis, and family history of liver disease or a human in the last stages of alcoholism can also be good reasons for testing.

What Abnormal Levels of Bilirubin Mean: Bilirubin is an orange yellow pigmentation in the blood and it is the result of the normal breakdown of the red blood cells by the body. A normal body processes the indirect bilirubin through the blood and into the liver. When it is in the liver, it attaches to sugars in the blood and becomes direct bilirubin. It is then moved into the bile and stored in the gallbladder until it is excreted through the stool. Anytime there is an abnormal level of either direct or indirect bilirubin, it can indicate a problem with the liver. The bilirubin testing is also done to investigate jaundice, which is a yellowing of the skin and the whites of the eyes. It can also determine whether there is a blockage in the liver bile duct. The bilirubin test is used to make an evaluation if there has been exposure to the hepatitis virus.
