Evaluation of liver function tests pptDhiraj Kumar
The document discusses liver function tests used to evaluate liver disease. It provides details on various tests including:
- Serum bilirubin, which detects liver cell damage and cholestasis. Elevated levels suggest viral or alcoholic hepatitis.
- Liver enzymes like ALT and AST reflect hepatocyte damage, while alkaline phosphatase, GGT, and 5'NT indicate cholestasis.
- Prothrombin time evaluates synthetic function and is a marker of severity in acute liver disease.
- Albumin reflects synthetic capacity but has a long half-life. Prealbumin and coagulation factors are more sensitive markers.
- Transient elastography can stage fibrosis non-invasively
The liver function tests typically include alanine transaminase (ALT) and aspartate transaminase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), serum bilirubin, prothrombin time (PT), the international normalized ratio (INR), total protein and albumin.
The document discusses various liver function tests that can help evaluate liver health. Tests that detect liver cell injury include alanine transaminase (ALT) and aspartate transaminase (AST), which are released when the liver cell membrane is damaged. Elevated levels of these enzymes suggest hepatocellular damage. Tests that indicate cholestasis and obstruction of bile flow include alkaline phosphatase, 5' nucleotidase, and leucine aminopeptidase. The ratio of AST to ALT can help differentiate conditions such as alcoholic liver disease. Together these tests provide insight into liver synthetic, metabolic and detoxification functions.

The document discusses liver function tests and what they indicate about liver health. It covers tests that detect hepatocellular injury like ALT and AST, tests that detect cholestatic disorders like alkaline phosphatase, and tests that assess hepatic protein synthesis like albumin. Elevations in ALT and AST generally indicate liver cell damage, while increases in alkaline phosphatase and GGT suggest problems with bile flow in the liver or bile ducts. Albumin levels reflect protein production by the liver, though other factors can also influence albumin levels. Together these tests provide insight into liver health and the type of underlying liver condition.
Liver function tests are used to:
1. Detect the presence of liver diseases
2. Distinguish between different types of liver diseases
3. Measure the extent of known liver damage
4. Monitor response to treatment
Common liver function tests include measurements of bilirubin, ammonia, serum enzymes, albumin, globulins, and coagulation factors. Elevations in certain enzymes and proteins provide clues to the type of liver disease, such as whether it involves hepatocyte damage or cholestasis. Following a patient's liver function tests over time also helps assess the severity of disease and response to treatment.
The liver has several important functions including metabolism, synthesis, and storage. Liver dysfunction can be caused by hepatocellular diseases, cholestatic diseases, cirrhosis, cancer, or genetic disorders. Diagnosis involves patient history, exams, labs, imaging, and biopsy. Liver function tests evaluate metabolism, damage to hepatocytes, cholestasis, and synthetic function. Elevations in certain enzymes and proteins provide clues to the type and severity of liver disease.
Jaundice, or icterus, is caused by the deposition of bilirubin in tissues resulting in a yellowish discoloration. Bilirubin deposition only occurs with hyperbilirubinemia and indicates either liver disease or a hemolytic disorder. Slight increases in bilirubin are best detected by examining the sclerae, which have an affinity for bilirubin. Bilirubin is produced from the breakdown of hemoglobin and transported bound to albumin to the liver where it is conjugated and excreted in bile and ultimately in feces. Laboratory tests are used to evaluate jaundice and determine if the cause is pre-hepatic, hepatocellular
This document discusses various biomarkers used in the diagnosis of liver disease. It describes how bile salts facilitate fat absorption and are excreted in urine during cholestasis. Primary and secondary bile salts are produced in the liver and intestines. Increased renal excretion of bile salts occurs during cholestasis. Liver enzymes like ALT, AST, ALP, GGT and 5-nucleotidase reflect hepatocyte damage and cholestasis. Elevated ALT and AST indicate hepatocellular injury. Increased ALP, GGT and 5-nucleotidase suggest cholestasis. Prothrombin time is prolonged in liver dysfunction due to decreased synthesis of clotting factors. Albumin and globulin
Liver function tests (LFT’s) are groups of laboratory blood assays designed to give information about the state of patients liver

The document discusses liver function tests (LFTs). It begins by providing an overview of liver anatomy and physiology. It then discusses the various functions of the liver including metabolic, excretory, protective, hematological, and storage functions. The goals of LFTs are outlined as detecting liver disease, distinguishing disease types, and monitoring treatment response. Common LFTs are described such as bilirubin, alkaline phosphatase, GGT, AST, ALT, albumin, and prothrombin time. Elevations in these enzymes and proteins can indicate liver damage or disease. Causes and interpretations of abnormal LFT results are provided.
This document discusses serum enzymes that can indicate liver disease states. It outlines enzymes that reflect hepatocyte damage like ALT and AST, as well as enzymes that indicate cholestasis such as alkaline phosphatase, GGT, and 5'-nucleotidase. ALT and AST are more specific to liver injury than other tissues. Alkaline phosphatase is also elevated in bone diseases. GGT and 5'-nucleotidase are more sensitive markers of cholestasis than alkaline phosphatase. The document also presents two case studies, one with signs of alcoholic liver disease and another with possible liver metastases from lung cancer.
The liver performs many essential functions including metabolic, excretory, hematological, storage, protective and detoxification roles. Liver function tests evaluate these roles by measuring biomarkers like bilirubin, liver enzymes, clotting factors, and drug metabolism. Elevations in biomarkers can indicate liver inflammation, injury, blockage or cancer. A combination of clinical history and liver function tests are used to diagnose specific liver disorders.
The document provides information about the liver and liver function tests. It discusses what the liver is and its key functions. These include excretion of bile, metabolic functions, hematological functions, storage of vitamins and minerals, and detoxification. It also describes jaundice, the metabolism of bilirubin, different types of liver function tests, and common liver diseases like acute viral hepatitis, chronic hepatitis, cirrhosis, liver failure, and alcoholic liver disease. Non-alcoholic steatohepatitis is also mentioned.
Liver Function Tests (LFTs) provide information about liver health and disease processes. They include tests of liver transport and metabolism (bilirubin, albumin), hepatocyte injury (aminotransferases, alkaline phosphatase), and biosynthetic function (proteins, ceruloplasmin). Bilirubin and albumin directly assess liver function, while enzymes indicate hepatocyte damage. Elevated enzymes suggest hepatitis. Bilirubin levels distinguish hepatocellular from cholestatic processes. Albumin declines with cirrhosis. LFTs help pharmacists monitor for drug-induced liver injury.
The document discusses the anatomy, functions, and tests related to evaluating the liver. It notes that the liver is the largest organ located in the upper right abdomen and contains hepatocytes as its main cells. The liver has important metabolic, excretory, hematological, storage, protective, and detoxification functions. Common tests to evaluate liver function include assessing serum enzymes like AST, ALT, ALP, GGT, and bilirubin levels. Tests can also examine the liver's metabolic capacity through galactose tolerance or its synthetic function using prothrombin time.
The document discusses liver function tests (LFTs) and their use in evaluating liver diseases. It provides details on 3 key LFTs:
1. Bilirubin tests which are used to diagnose prehepatic (hemolytic), hepatic, and obstructive jaundice. Elevated conjugated bilirubin indicates obstructive jaundice while elevated unconjugated bilirubin indicates hepatic or hemolytic jaundice.
2. Liver enzymes like ALT, AST, ALP, and GGT which provide information on liver health and injury. Elevated ALT and AST indicate liver parenchymal damage while elevated ALP and GGT can indicate obstructive jaundice.

3. STRUCTURE
Heaviest organ in the body
(weighs 1.0—1.5 kg.)
Majority of cells are hepatocytes.
(2/3rd of liver mass.)
Remaining — Kupffer cells, Ito cells,
Endothelial cells, Bile ductular cells
Blood supply :dual blood supply- 20%
hepatic artery & 80% from the portal vein.
4. STRUCTURE
Organised in lobules with portal areas at
periphery and central veins in centre.
Functionally organised into acini
Zone 1 - portal area
Zone 2 - hepatocytes
Zone 3 - central veins.
Blood flows from Zone 1 to Zone 3.
8. Synthesis of proteins (albumin, coagulation
factors, hormonal and growth factors)
Production of bile and its carriers (bile acids,
cholesterol, lecithin, phospholipids)
Regulation of nutrients (glucose, glycogen, lipids,
cholesterol, amino acids)

compounds (bilirubin, drugs, ammonia) for
excretion in the bile or urine.
9. LIVER FUNCTION TESTS
2 types –
Based on
Detoxification and
Excretory Functions
Tests that Measure
Biosynthetic Function
of the Liver
10. Based on Excretory Functions :
Serum Bilirubin :
Breakdown product of heme-containing
proteins found in the blood
Two fractions — conjugated (direct, soluble) –
increases in liver & biliary disease
Unconjugated (indirect, bound to albumin) –
increases in hemolysis
Normal value – 0.3 to 1 mg/dl.
11. Serum Enzymes
Two categories:
(1) Reflect damage to hepatocytes: AST &
ALT
(2) Reflects cholestasis : alkaline
Phosphatase (ALP) & 5’ nucleotidase
12. AST & ALT
Released into the blood in greater amounts during
damage to the liver cell membrane.
ALT is found primarily in the liver.
Normal value 5-40mg/dl.
Pattern of elevation is helpful diagnostically. In
acute hepatocellular disorders, ALT > AST. An
AST:ALT ratio > 2:1 is suggestive while a ratio > 3:1
is highly suggestive of ALD.
13. Alkaline phosphatase (ALP)
Distinct isoenzymes found in the liver, bone,
placenta
Normal value 80-140mg/dl.
During obstruction to biliary tract ALP is
produced excessively
GGT
Raised in biliary obstruction
More specific for liver
14. Transaminases
May not be elevated in chronic liver disease
Cirrhosis
Minimal ALT elevations (<1.5 X normal)
Race/Gender
Obesity
Muscle injury
15. Transaminases
Mild elevations – more to come
Marked elevations
Acute toxic injury- i.e. Paracetamol, ischemia
Acute viral disease
Alcoholic hepatitis
17. Mild Transaminase elevation
AST or ALT < 5 times upper limit of normal
Etiologies
Hepatic: (ALT-predominant)
Chronic Hep C ▪Hemochromatosis
Chronic Hep B ▪Medications/Toxins
Acute viral hep ▪Autoimmune Hep
Steatosis ▪Alpha1 Antitrypsin Def
Wilson’s Disease ▪Celiac Disease
24. Tests that Measure Biosynthetic Function
of the Liver
Serum Albumin
Synthesized exclusively by hepatocytes
Hypoalbuminemia is more common in chronic
liver disorders such as cirrhosis
Normal value 3.5 – 5mg/dl
Serum Globulins
Increase in specific isotypes of globulins occurs
in chronic liver diseases
25. Coagulation Factors
Made exclusively in hepatocytes
Due to rapid turnover, single best acute measure of
hepatic synthetic function
Serum prothrombin time - collectively measures
factors II, V, VII, IX and X.
Normal value 11-12.5sec.
26. PROTHROMBIN TIME
The prothrombin time (PT) does not become
abnormal until more than 80 percent of liver
synthetic capacity is lost.
Factor VII has a short half-life of only about six
hours.
Single best acute measure of hepatic synthetic
function.
27. PROTHROMBIN TIME
Factors II, VII, IX and X requires vitamin K for
biosynthesis.
PT can be prolonged in hepatitis, cirrhosis or in
Vit K deficiency.
Trial of vit K injections (e.g., 5 mg/day s for three
days) is the most practical way to exclude vitamin
K deficiency.
Prolongation of PT > 5 sec above control and not
corrected by vit K is a poor prognostic sign.
28. SERUM ALBUMIN
Synthesised exclusively by the liver.
Half life—15-20 days.
Not a good indicator of acute hepatic dysfunction.
Sign of chronic liver disease.
29. SERUM GLOBULINS
Gamma globulin fraction synthesised by B cells.
Alpha and beta fractions by liver.
Gamma globulins increase in chronic liver
disease.
30. Jaundice or icterus, is yellowish
discoloration of tissue resulting from the
deposition of bilirubin.
Clinical jaundice – S Bilirubin >2.5mg%
JAUNDICE
31. NORMAL BILIRUBIN
METABOLISM haem (from RBCs) is oxidised to Bili verdin by
an enzyme - heme oxygenase
Biliverdin is reduced to Bili rubin by Bili verdin
reductase
Uptake of bilirubin by the liver is mediated by
a carrier protein (receptor)
On the smooth ER, bilirubin is conjugated with
glucoronic acid catalyzed by UDP glucuronyl
tranferase
“Conjugated” bilirubin is water soluble and is
secreted by the hepatocytes into the biliary
canaliculi
Converted to stercobilinogen (urobilinogen)
(colorless) by bacteria in the gut
Oxidized to stercobilin which is colored
(excreted in feces)

33. Classification
Based on the pathological
mechanism giving rise to
jaundice
1. Hemolytic jaundice
2. Hepatocellular jaundice
3. Cholastatic jaundice
