    Bilirubin

    Bilirubin

    Get a free nursing lab values cheat sheet at NURSING.com/63labs
     
    Objective: Determine the significance and clinical use of measuring Direct or Conjugated Bilirubin in clinical practice
     
    Lab Test Name: Direct or Conjugated Bilirubin
     
    Description: Bilirubin is a substance made when your body breaks down old red blood cells. This is a normal process. Bilirubin is also part of bile, which your liver makes to help digest the food you eat.
    A small amount of bilirubin in your blood is normal.
    Some bilirubin is bound to albumin in the blood. This type of bilirubin is called unconjugated, or indirect, bilirubin.
    In the liver, bilirubin is changed into a form that your body can get rid of. This is called conjugated bilirubin or direct bilirubin. 
    This bilirubin travels from the liver into the small intestine. A very small amount passes into your kidneys and is excreted in your urine. This bilirubin also gives urine its distinctive yellow color and contributes to the brown color of stool.
     
    Indications: Newborns – immature liver has trouble clearing bilirubin and manifests as jaundice Investigate jaundice in adults Blockage of bile ducts- (liver or gallbladder) Detection of liver disease- particularly hepatitis Monitor progression of hepatitis Detect issues with RBC breakdown→hemolytic anemia Suspected drug toxicity- many medications are metabolized and cleared in the liver  
    Normal Therapeutic Values: Normal – 0.0-0.2 mg/dL
    Collection:
    Plasma separator tube  
    What would cause increased levels? Increased levels linked to:
    Poor liver function or hepatitis Certain medications Hemolytic anemia Pregnancy Sepsis- poor perfusion Exercise TPN ETOH  
    What would cause decreased levels? Studies are inconclusive regarding risk or association with disease process in the presence of a decreased bilirubin level.

    What is the Lab Name for Aspartate Aminotransferase (AST) Lab Values?

    Aspartate Aminotransferase








    What is the Lab Abbreviation for Aspartate Aminotransferase?

    AST








    What is Aspartate Aminotransferase in terms of Nursing Labs?

    Aspartate aminotransferase (AST) is an enzyme primarily found in liver and heart cells and to a smaller extent, AST can also be found in the pancreas, kidneys, skeletal muscle, and brain. Levels of AST increase from cell death (necrosis) because the AST enzyme is released into the blood.








    What is the Normal Range for Aspartate Aminotransferase?

    12-37 U/L








    What are the Indications for Aspartate Aminotransferase?

     
    Monitor progression of: Liver disease Response to treatments. Monitor liver toxic medications  








    What would cause Increased Levels of Aspartate Aminotransferase?

     
    Liver disease Liver cancer Shock Congestive Heart Failure (CHF) Pericarditis Biliary tract obstruction Dermatomyositis Pancreatitis Muscular Dystrophy CVA Hemolytic anemia Delirium Tremens (DT)  








    What would cause Decreased Levels of Aspartate Aminotransferase?

    What is the Lab Name for Amylase Lab Values?

    Amylase
     








    What is Amylase in terms of Nursing Labs?

    Amylase is made in the pancreas. It is an enzyme that breaks down carbohydrates to allow our body to absorb it. Monitoring amylase levels can identify problems with the pancreas.
     








    What is the Normal Range for Amylase?

    0-130 U/L
     








    What are the Indications for Amylase?

    Diagnosing: Pancreatitis Pancreatic Duct Obstruction Macroamylasemia Trauma to Pancreas  








    What would cause Increased Levels of Amylase?

    Pancreatitis Pancreatic Cancer Pancreatic Cyst DKA Peritonitis Abdominal Trauma Duodenal Obstruction Mumps Alcohol use












     






    What would cause Decreased Levels of Amylase?

    What is the Lab Name for Ammonia (NH3) Lab Values?

    Ammonia
     








    What is the Lab Abbreviation for Ammonia?

    NH3
     








    What is Ammonia in terms of Nursing Labs?

    Ammonia (NH3) is a byproduct created when protein is broken down. Ammonia is converted into urea in the liver, and urea is excreted by the kidneys. During liver disease, ammonia levels rise and can have a negative effect on the brain.
     








    What is the Normal Range for Ammonia?

    19-60 mcg/dL
     








    What are the Indications for Ammonia?

    Identifying liver disease Monitoring hepatic encephalopathy Evaluating effectiveness of treatment.  








    What would cause Increased Levels of Ammonia?

    Liver Failure Hepatic Coma (Hepatic Encephalopathy) Reye’s syndrome Total Parental Nutrition (TPN) Gastrointestinal Hemorrhage












     














    What would cause Decreased Levels of Ammonia?

    Located in several places in the body:
    Liver Intestines Biliary tract Bones Placenta Different isoenzymes of ALP are used to determine:
    Liver, bone, intestine and other cancers Bone turnover in postmenopausal women

    What is Albumin in terms of Nursing Labs?

    Albumin is a transport protein in the blood. It helps maintain the oncotic pressure of the blood. Albumin levels will drop if synthesis is slowed, protein intake is inadequate, or there are increased losses. Albumin has a long half life, however, so levels are not a good indicator of acute illness.
     








    What is the Normal Range for Albumin?

    3.5 – 6.0 g/dL

Compact and complete

Excellent source for a recap of past classes. It can be essential for new nurses in the floor specially ER, ICU. I love the most the fact that they take just a few minutes and during that time frame explains the basic reasoning for the test and most importantly it’s translation in patient care.
Really wish you could expand the number of tests even though they might not necessarily be common in most institutions.
Great work and thank you for everything you’ve done so far.

Wonderful

These podcasts have been invaluable to studying for nursing school! They're encouraging and easy to understand. I can play them in the car while I'm travelling, at the gym while I'm working out, or just working around the house. Love them.
