This document discusses various laboratory tests used to evaluate liver function. It describes tests that examine the liver's excretory function like bilirubin, its enzyme levels like ALT and AST, and synthetic function by measuring albumin and prothrombin time. A variety of tests are employed to get a full picture of liver health, as each provides different diagnostic information. Combining test results with a patient's history helps physicians accurately diagnose liver disorders.
The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.
Liver function tests (LFTs) evaluate liver health and detect liver damage. LFTs measure enzymes released from damaged liver cells (ALT, AST), synthetic function (albumin, clotting factors), and signs of obstruction (bilirubin, ALP, GGT). Elevations in ALT and AST indicate hepatocyte injury while increased bilirubin, ALP, and GGT suggest cholestasis or blockage of bile flow. LFTs help diagnose liver diseases, determine severity, monitor treatment effectiveness, and assess operative risk or need for transplantation.

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 has many essential functions and there is no way to compensate for loss of liver function long-term. Liver function tests are used to detect and diagnose liver disease by measuring biomarkers related to the liver's detoxification, excretory, and biosynthetic functions. Key tests include serum bilirubin, liver enzymes AST and ALT, alkaline phosphatase, serum albumin, and prothrombin time. Elevations provide clues to identify pre-hepatic, hepatic, or post-hepatic causes and whether damage is hepatocellular or cholestatic in nature.

Enzymes are proteins that catalyze biochemical reactions without being altered. They are present at higher concentrations in cells than plasma. Elevated plasma enzyme levels can indicate cell damage or proliferation. Each enzyme has an active site that binds to substrates, and some have allosteric sites for regulatory molecules. Isoenzymes are multiple forms of the same enzyme that differ in structure. Measuring plasma enzyme levels helps diagnose tissue damage or diseases of organs like the heart, liver, and muscles.
Jaundice, also known as hyperbilirubinemia, is caused by an excess of bilirubin in the blood and results in a yellow discoloration of the skin and eyes. It can be categorized as pre-hepatic, hepatic, or post-hepatic based on where the underlying disorder occurs in the pathway of bilirubin metabolism and excretion. Pre-hepatic jaundice is caused by issues prior to the liver like hemolytic anemias. Hepatic jaundice results from liver disease or drugs affecting the liver. Post-hepatic jaundice is due to gallstones or other issues blocking bile ducts after the liver. Laboratory tests can help distinguish between the types

The document discusses pancreatic digestive enzymes including amylase and lipase. It notes that amylase breaks down starches into smaller units and is produced in the pancreas and salivary glands. Elevated amylase levels can indicate acute pancreatitis or other conditions. Lipase breaks down fats and is also produced primarily in the pancreas. Lipase levels are more specific for pancreatic disorders than amylase and remain elevated longer in acute pancreatitis. Both enzymes can be measured using colorimetric or other laboratory methods.
Jaundice or icterus is used to describe the yellow discoloration of skin , eyes and mucous membranes most resulting from retention of bilirubin.
The upper limit of normal for total bilirubin is 0.2 to 1.2mg/dl, jaundice is not noticeable until bilirubin levels reached to 3 to 5 mg/dl.
Icteric term commonly used in clinical lab refer to a serum or plasma with yellow discoloration

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.

Vitamin K for their synthesis, the absorption of which is dependent on
the presence of bile in the small intestine.
4. 3) Excretion and secretory function :Major haem waste product
bilirubin into bile. Excretion of bile pigments bile salts
4) Detoxification function and protective function: ammonia is
detoxified to urea and certain drugs Steroids are inactivated by
conjugation as glucuronides and sulphates before excretion in urine
• Kupffer cells: (phagocytosis), The Kupffer cells remove certain toxic
substances coming from portal circulation before they enter the
general circulation.
5) Storage function: glycogen, fat soluble vitamins D,A, trace elements
and iron.
5. • Derangement of liver functions, singly or in combination, may occur
when liver is assaulted by:
• • Viruses
• • Drugs
• • Industrial chemicals
• • Hypoxia due to shock, congestive cardiac failure ,liver cirrhosis
• • Prolonged biliary obstruction.
• In addition, the disease process also destroys the liver cells and this
causes leakage of intracellular enzymes into plasma where their level
rises.
6. Importance of LFTS
• To assess the severity of the disease
• To differentiate different types of jaundice
• To find out the presence of latent disease
7. LFTS
• These test simply provide exsistance, extent, damage
• Classification of LFTS
1. Test based on excretory function
2. Test based on detoxification function
3. Test based on synthetic function
4. Test based on enzymatic activity
5. Test on metabolic activity
8. Test based on excretory function
• Test related with bilirubin metabolism
• Test related with bile acid metabolism
• Deficiency of bile acids then patients will suffer from steahorrea
• Malabsorption of fats
• Test based on dye-excretion BSP bromosulphthalein test
• Estimation of urobilinogen in urine and feaces
• Colour of stool examination
9. 2) Test based on serum enzymes derived from liver
• ALT
• AST
• ALP
• Gamma-glutamy transpeptidase GGT
• 5-nucletidase enzyme 5NT
10. 3) Test based on metabolic activity
• Galactose tolerance test GTT
• Estimation of esterified cholesterol
4) Test based on synthetic function
• Serum albumin and A/G ratio
• Coagulation factors (Prothrombin time) PT
• Total protein estimation
5) Test based on detoxification
• Estimation of blood urea and ammonia
• Hippuric acid synthesis
11. Test based on Synthetic function
• Although these tests are not sensitive to minimal liver damage
• Useful in quantitating the severity of hepatic dysfunction
• A decreased serum Albumin correlates with severity of functional
impairement
• Found in chronic liver disease rather than in acute liver disease.
• Serum alpha globulin in CLD. Serum gamma globulins in acute
liver disease and CLD, cirrhosis.
• Ig G and Ig M in chronic active hepatitis
• Ig A in alcoholic cirrhosis
12. • Prothrombin time in jaundice and liver disease because the liver
is unable to synthesize adequate amount of clotting factor or because
of disruption of bile flow results in inadequate absorption of vitamin
K.
• Measurement of PT is useful in following the progression of disease
• May be prolonged by cholestasis
• Assesement of risk of bleeding
• A marked increase indicates diffuse liver disease and a poor
prognosis.
13. • Total protein estimation
• A/G ratio
• Globulin = albumin- total protein
14. Test based on Detoxification function
• Serum ammonia level
Liver failure ammonia other toxins increase in blood leads to hepatic coma
hepato-encephalopathy
• Hippuric acid test
Hippuric acid is produced in liver when benzoic acid combines with glycin
3gm should excreted in healthy person
Smaller amount when there is acute or chronic liver damage or infectious
hepatitis
15. Test based on Enzymatic function
• Enzymes play an important role in differentiating hepatocellular from
obstructive liver disease. If the obstruction not rapidly treated it may
leads to liver failure.
• Hepatocyte damage
• AST and ALT
• A rise in plasma aminotransferase activity sensitive indicator of
damage to cytoplasmic or mitochondrial membrane
• Liver cells contain more AST than ALT.ALT is confined to cytoplasm in
which its concentration is high than AST.
16. • In viral hepatitis the cytoplasmic membrane sustains the more
damage thus ALT greater increase than AST.
• In infiltrative disorders in which there is damage to both
mitochondrial and cytoplasmic membrane there is greater increase in
AST than ALT.
• The relative plasma activities of ALT and AST may help to indicate
type of cell damage.
• A plasma AST:ALT ratio of > 2 suggestive but not diagnostic of
alcoholic disease
• <1 ratio suggests chronic viral hepatitis.
17. • ALT is found mainly in liver(lesser amount in kidney,skeletal muscle)
• ALT is more liver specific
• AST is widely distributed in equal amounts in heart ,skeletal muscle
and liver.
• AST and ALT raised in acute conditions acute viral hepatitis drug and
toxin induced liver necrosis and ischemia.
• ALT is more elevated than AST.
18. • Test of obstruction
• ALP (Alkaline phosphatase)
• Localized in microvilli of bile canaliculi
• Widely distributed in all tissues high in liver bone kidney and placenta
• Marker of extra hepatic biliary obstruction
• Intra hepatic cholestasis
• Thus both conjugated bilirubin and ALP will be elevated in cholestasis
liver disease.
• Bone related disorders
19. GGT
• Gamma-glutamyl transferase
• It is an enzyme derived from endoplasic reticulum of cells of
hepatobiliary tract.
• Also found in liver kidney pancreas intestine prostate but not in bone.
• As this reticulum proliferates for example in response to prolonged
alcohol intake and drugs synthesis of enzyme is induced. There fore
raised plasma activity does not indicate hepatocellular damage but
may reflect enzyme induction or cholestasis.
• Highest level in biliary obstruction
