  1. Purpose of Lab test
    • Screening
    • -----Evaluates medical condition
    • -----Reveals potential precautions or contraindications to care
    • Diagnosis
    • Monitoring
  2. Limitations of lab tests
    • False-negatives
    • False-positives
    • Therefore look for trends over time and with other info for physiological status (vital signs)
  3. Lab Values vary by…
    • lab
    • Gender
    • Age
    • ---Newborn/kids have higher WBC
    • Weight
    • Physiologic status
  4. Base lab values on
    • APTA Guidelines
    • Lab Values Update 2013
    • Look for trends
  5. Benefits of abbreviations
    Save time
  6. Risks of abbreviations
    • Not everyone uses same abbreviation
    • Context
  7. Basic Metabolic Panel (BMP)

    • Ca
    • Mg
  10. Sodium – Na+
    • Most susceptible to fluid volume
    • Looks to see if someone is still in homeostasis
  11. Potassium – K+
    • Nerve excitability
    • ----especially cardiac muscle (can lead to cardiac arrhythmias)
  12. Calcium – Ca+
    • Neuromuscular activity
    • ----Increased muscle contraction or lack of contraction
  13. Magnesium – Mg
    • Regulation of excitable cells
    • Looks to see if in homeostasis, never excitability, neuromuscular activity
    • Can see cardiac, muscle issues, numbness (all of the above)
  14. Blood Glucose tests
    • Fasting glucose
    • Hba1c
