|
Reference Range
|
-range of normal values
-calculated as "central 95%" of results in a healthy population |
|
|
Critical Value
|
-lab test that is so abnormal that it is life threatening and needs immediate Tx
-lab is required to inform pt of critical values |
|
|
What occurrs with high potassium levels?
|
cardiac arrhytmia and sudden death
|
|
|
What occurrs with low calcium levels?

seizures
|
|
|
Diagnostic Algorithm
|
-the steps that lead to a final diagnosis
|
|
|
Basic Metabolic Panel
|
*tests electrolyte, acid/base, kidney disease, & DM*
1. Electrolytes = Na, K, Ca, Cl, HCO3; Kidney = creatinine, BUN; Glucose |
|
|
Reference Range for Glucose
|
60-100 mg/dL
Abnormal Results caused by hyperglycemia or hypoglycemia |
|
|
Comprehensive Metabolic Panel
|
Basic Metabolic Panel + Liver F(x) Tests:
ALT = alanine aminotransferase AST = aspartate aminotransferase alkaline phosphatase bilirubin albumin total protein |
|
|
What is the importance of ALT and AST?
|
ALT and AST are liver, cardiac, skeletal muscle enzymes involved in making AA's. If elevated (>35 IU/L), indicates liver, cardiac, or skeletal muscle disease.
|
|
|
Complete Blood Count
|
*RBCs, WBCs, Platlets*
A. Red Cell Parameters -Hb -Hematocrit -Red Cell Count -Mean Rec Cell Vol -Mean Red Cell Hb -Mean Red Cell [Hb] -Red Cell Vol Dist Width B. White Cell Parameters -White Cell Count -Neutrophils -Basophils -Monocytes -Lymphocytes -Eosinophils C. Platelet Parameters -Platelet Count -Mean Platelet Vol |
|
|
Reference Range for WBC's:
|
4500-11,000 per uL blood
|
|
|
A. Elevated Neutrophils Indicates:
B. Elevated Lymphocytes Indicates: C. Elevated Eosinophils Indicates: |
A. High Neutrophils = bacterial infection
B. High Lymphocytes = viral infection C. High Eosinophils = parasitic infection |
|
|
