Labs for NURS 370
Show Answers:

  1. Albumin
    • a protein that aids in circulating/transporting hormones and medications
    • determine liver and kidney function
    • helps in regulating blood
    • low albumin can suggest liver disease or inability for the kidneys to retain albumin (lost in urine)
    • low albumin can be seen in malnutrition and inflammation
    • high levels of albumin can be seen in dehydration
  2. Alkaline Phosphate (ALP)
    • located in the liver
    • used to help detect liver disease
    • increased amounts of ALP indicate liver dysfunction, which may cause build up of toxins in the liver (liver filter function)
  3. Brain Natriuretic Peptide (BNP)
    • helps to detect, diagnose, and evalute the severity of heart failure
    • increased BNP indicates worsening HF
  4. Blood Urea Nitrogen (BUN)
    • used along with creatinine test to evaluate kidney function
    • increased BUN suggests impair kidney function
  5. C-reactive protein (CRP)
    non-specific test used to identify inflammation (systemic)

    high CRP may indicate inflammation; however, will not indicate the location or the condition causing it
  6. CBC w/ diff
    • broad screening used to test disorders (such as anemia and infection)
    • consists of WBC, RBC, hemoglobin (amount of O2 carrying protein), hematocrit, platelet count
    • decrease in RBC and hemoglobin may indicate anemia
    • increase in hematocrit equals low blood volume
    • decreased hematocrit = high blood volume
  7. Electrolytes
    used to identify or monitor electrolyte or acid-base imbalances
  8. Homocytesine
    • used to determine if a person is vitaminB12 or folate deficiency
    • maybe ordered for people who are at risk for heart attack or stroke
  9. Lipid profile
    • used to determine the risk for coronary heart disease
    • consists of cholesterol (HDL and LDL) and triglycerides
  10. PT/PTT
    • measures the ability for the blood to clot and it can help diagnose bleeding disorders
    • prolong or increased PT suggests the blood istaking too long to clot
    • increased PT suggests liver dysfunction because platelets are orginated from the liver
    • PT has been adjusted to INR (international normalized ratio) for patient using anti-coagulants
  11. Troponin I
    • used for people who report having chest pain, which may indicate a heart attack
    • elevated level suggests damage to the heart (heart attack)
  12. Type, screen & cross match
    used for blood transfusion
