Lab Tests & Values Flashcards
Reference Range or Expected Value
range of values for a given test in a healthy person
APACHE
Acute Physiology and Chronic Health Evaluation;
system for prognosis development for critically ill patients
based on admission diagnosis, age, health history, physiologic measurement taken during first 24 hrs.;
calculates a predictive death rate or predicted length of stay in the ICU
Basic Metabolic Panel (BMP)
group of 8 specific tests for electrolyte level, acid-base balance, blood sugar, & kidney status
BMP tests
serum concentrations of sodium, potassium, chloride, calcium, blood urea nitrogen (BUN), creatine, glucose, & carbon dioxide
Reference value - Sodium
Infant = 134-150 mEq/L Child = 135-145 mEq/L Adult = 135-145 mEq/L
Critical value - Sodium
Adult = < 110
Reference value - Potassium
Infant = 3.6-5.8 mEq/L Child = 3.5-5.5 mEq/L Adult = 3.5-5.0 mEq/L
