Diagnostic studies
Diagnostic Studies

  • Serum Bilirubin Test

    • Normal Values

      • Direct bilirubin: 0.1 to 0.3 mg/dl

      • Indirect bilirubin: 0.2 to 0.8 mg/dl

      • Total bilirubin: 0.1 to 1.0 mg/dl

      • Total bilirubin in newborns: 1 to 12 mg/dl

    • Rationale

      • Used to diagnose liver disease, biliary obstruction, erythroblastosis fetalis, and hemolytic anemia

    • Nursing Interventions

      • NPO


Diagnostic studies1
Diagnostic Studies

  • Liver Enzyme Tests

    • Normal Values

      • AST (SGOT): 5-40 IU/L

        • elevated with MI, hepatitis, cirrhosis, hepatic necrosis, hepatic tumor, acute pancreatitis, acute renal failure, and acute hemolytic anemia

      • ALT (SGPT): 5-35 IU/L

        • elevated with hepatitis, cirrhosis, hepatic necrosis, hepatic tumors, and hepatotoxic drugs.

      • LDH: 45-90 U/L

        • elevated with MI, pulmonary infarction, hepatic disease, pacreatitis, hemolytic anemia, and skeletal muscle disease.


Diagnostic studies2
Diagnostic Studies

  • Alkaline Phosphatase: 30-85 ImU/L

    • elevated in obstructive disorders of the biliary tract, hepatic tumors, cirrhosis, primary and metastatic tumors, hyperparathyroidism, metastatic tumor in bones and healing fractures

  • Gamma GT: 4-38 U/L

    • elevated with hepatitis, cirrhosis, hepatic tumors, hepatotoxic drugs, MI (4-10 days after), CHF, and alcohol ingestion

  • Rationale

    • Liver is storehouse for many enzymes

    • Injury or diseases affecting the liver will cause release of these enzymes into the bloodstream


  • Diagnostic studies3
    Diagnostic Studies

    • Serum Protein Test

      • Normal Values

        • Total Protein: 6-8 g/dl

        • Albumin: 3.2-4.5 g/dl

        • Globulin: 2.3 to 3.4 g/dl

        • Albumin globulin (A/G ratio): 1.2 to 2.2 g/dl

      • Rationale

        • The liver metabolizes protein, esp. albumin. If the liver is diseased it loses the ability to metabolize the albumin and the serum albumin level is decreased


    Diagnostic studies4
    Diagnostic Studies

    • Oral Cholecystography (Gallbladder Series)

      • Rationale

        • Provides x-ray visualization of the gallbladder after ingestion of a radiopaque dye.

        • The following factors are necessary for adequate dye concentration:

          • Ingestion fo correct number of dye tablets

          • Adequate absorption of the dye from the GI tract; no vomiting or diarrhea

          • Abstinence from food the morning of the test

          • Patency of the cystic duct

          • Concentration of the cye within the gallbladder


    Diagnostic studies5
    Diagnostic Studies

    • Nursing Interventions

      • Assess for allergies to iodine

      • Administer 6 Telepaque tablets orally, after the evening meal

      • NPO after midnight


    Diagnostic studies6
    Diagnostic Studies

    • Intravenous Cholangiography (IV Cholangiogram)

      • Rationale

        • Radiographic dye is administered IV

        • Allows visualization of the hepatic and common bile ducts and also the gallbladder if the cystic duct is patent

        • Used to visualize stones, strictures, or tumors of the hepatic duct, common bile duct, and gallbladder.


    Diagnostic studies7
    Diagnostic Studies

    • Operative Cholangiography

      • Rationale

        • Common bile duct is injected directly with radiopaque dye.

        • Visualization of stones or other obstructions during surgery to prevent unneccessary common bile duct exploration


    Diagnostic studies8
    Diagnostic Studies

    • T-Tube Cholangiogram

      • Rationale

        • Demonstrates good flow of contrast into the duodenum

        • Diagnose retained ductal stones and/or leaks in ducts

      • Nursing Interventions

        • T-tube to closed drainage system

        • Cover site with sterile dressing, if t-tube removed

        • Assess for allergies to iodine

        • NPO after midnight


    Diagnostic studies9
    Diagnostic Studies

    • Ultrasound of the Liver, Gallbladder, and Biliary System

      • Rationale

        • Visualization of deep structures by recording the reflections of ultrasonic waves directed in to the tissue

      • Nursing Interventions

        • NPO after midnight

        • Should be done before barium studies or after all barium has been expelled


    Diagnostic studies10
    Diagnostic Studies

    • Gallbladder Scanning

      • Rationale

        • Injection of technetium 99 is given and scan is done to visualize the gallbladder and biliary tract

        • Used to diagnose acute cholecystitis

      • Nursing Interventions

        • NPO after midnight


    Diagnostic studies11
    Diagnostic Studies

    • Liver Biopsy

      • Rationale

        • Needle is inserted through the abdominal wall into the liver to remove a piece of liver tissue

        • Used to diagnose cirrhosis, hepatitis, drug-related reactions, granuloma, and tumors

      • Nursing Interventions

        • Informed consent

        • NPO for 4-8 hours

        • Assess lab results for normal platelet count and prothrombin time


    Diagnostic studies12
    Diagnostic Studies

    • After biopsy

      • Assess for s/s of bleeding

      • Nursing Interventions

        • NPO after midnight


    Diagnostic studies14
    Diagnostic Studies

    • Blood Ammonia

      • Normal Value

        • 15 to 110 micrograms/dl

      • Rationale

        • Ammonia is normally converted into urea and then excreted by the kidneys

        • Liver dysfunction or altered blood flow to the liver causes blood ammonia levels to rise and BUN (blood urea nitrogen) to decrease

      • Nursing Interventions

        • Notify lab if patient is currently taking Neomycin; can cause decreased ammonia levels


    Diagnostic studies15
    Diagnostic Studies

    • Hepatitis Virus Studies

          • A, B, C, D, and E


    Diagnostic studies16
    Diagnostic Studies

    • Serum Amylase Test

      • Normal Value

        • 25 to 125 U/L

      • Rationale

        • Damage to pancreas cells or obstruction to the pancreatic ductal flow will cause an outporing of this enzyme and absorption into the bloodstream

        • Levels will rise within 12 hours of onset of pancreatic disease.

        • Rapidly cleared by the kidneys; levels may return to normal within 48-72 hrs

      • Nursing Interventions

        • Note administration of any IV dextrose; can cause a false-negative result


    Diagnostic studies17
    Diagnostic Studies

    • Urine Amylase Test

      • Normal Value

        • 3-35 IU/hr

      • Rationale

        • Disorders affecting the pancreas will cause elevated amylase levels in the urine because the kidneys rapidly clear amylase

        • Levels remain elevated in the urine for 7-10 days

        • Used to diagnose pancreatitis in patients who have had symptoms for 3 days or longer


    Diagnostic studies18

        • Discard first urine specimen

        • Collect all subsequent urine, including the last urine voided exactly 2, 6, 12, or 24 hrs after collection began

        • Urine should be kept on ice during collection period


    Diagnostic studies19
    Diagnostic Studies

    • Ultrasound of Pancreas

      • Rationale

        • Provides diagnostic information with the use of ultrasonography of the pancreas

        • Used to diagnose carcinoma, pseudocyst, pancreatitis, and pancreatic abcess

      • Nursing Interventions

        • NPO for 8 hours before test

        • Gas or barium will interfere with sound wave transmission

        • NPO after midnight

        • Some patients may experience claustrophobia


    Diagnostic studies21
    Diagnostic Studies

    • Endoscopic Retrograde Cholangiopancreatography of the Pancreatic Duct (ERCP)

      • Rationale

        • A fiberoptic duodenoscope is inserted through the oral pharynx, through the esophagus and stomach, and into the duodenum. Dye is injected for radiographic visualization of the CBD and pancreatic duct.

        • Used to diagnose obstructive jaundice, remove common bile duct stones, and place biliary and pancreatic duct stents to bypass obstructions
