Liver Function Tests And Their Interpretation Pdf Liver function tests (lft) are a helpful screening tool, which are an effective modality to detect hepatic dysfunction. since the liver performs a variety of functions so no single test is sufficient to provide complete estimate of function of liver. What are the lfts? in and other proteins, and bilirubin. the liver enzymes a e produced by cells within the liver. they include alkaline phosphatase (alp), γ–glutamyl transpedtidase (ggt), alanine aminotransferase (alt) and aspartate aminotransferase (ast), but the combination of liver enzyme results you rec.
Liver Function Test Pdf Liver Hepatitis When appropriately ordered and interpreted, serum biochem ical tests, the so called “liver function tests” or “liver chemis tries,” can be useful in the evaluation and management of patients with liver disorders. The liver function test (lft) is a commonly requested test, and abnormal results are often detected in asymptomatic patients. the components of the test profile are total (t bili) and direct or unconjugated bilirubin (d bili), aspartate aminotransferase (ast), alanine aminotransferase (alt), alkaline phosphatase (alk phos), gamma. Liver function tests help your doctor check your liver’s health and detect liver damage. these blood tests mea sure the levels of certain proteins and enzymes in your blood. proteins are large molecules that are needed for your overall health. enzymes are cellular proteins that help important chemical reactions to occur in your body. Liver function tests include estimation of the serum levels of four important enzymes in the liver. an increase in the serum levels of these enzymes indicates liver injury. each of these enzymes is located in specific areas within the hepatocytes and cholangiocytes.

Liver function tests include estimation of the serum levels of four important enzymes in the liver. an increase in the serum levels of these enzymes indicates liver injury. each of these enzymes is located in specific areas within the hepatocytes and cholangiocytes. There are two main patterns of lft abnormalities that can provide clues about the location or type of liver dysfunction: 1. hepatocellular injury – reflected by increased aminotransferase levels (alt and ast). the ast:alt ratio may be helpful in determining both the aetiology and the stage of liver disease (see main text). 2. Lfts comprise a panel of blood tests used to assess various aspects of liver function, including hepatocellular integrity, biliary excretion, and synthetic capacity. due to the liver’s multifunctional role, no single test can comprehensively evaluate its function. Assessment of functional status of liver generally requires laboratory tests. number of tests are required to assess hepatic functions all the tests need not be performed in every patient. bile pigments, bile salts and urobilinogen in urine. a rise in serum bilirubin above 2mg dl leads to yellow staining of tissues. In clinical medicine tests have been used chiefly for one or more of four reasons: (1) to demonstrate the existence of hepatic disease; (2) to identify the degree and type of liver pathology present; (3) to differentiate between the clinical varieties of jaundice; and (4) to follow the course of hepatic disease and thus establish a prognosis.
