Study Notes
Interpreting Clinical Laboratory Values
- Erythropenia is characterized by a reduced number of RBCs, Hgb, & Hct.
- Platelets (Thrombocytes) range from 150,000-400,000/m3 or 150-400x 10^9/L.
- White blood cells (Leukocytes) typically range from 5,000-10,000/mm3.
- Neutrophils are responsible for killing and digesting bacterial organisms.
- Coagulation studies analyze the clotting factors of blood, including PT, INR, and PTT.
- PT and INR measure the adequacy of the extrinsic clotting cascade pathway and common pathway in the clotting mechanism.
- Coumadin (Warfarin) is an anticoagulant that directly affects clotting factors.
- PTT evaluates the adequacy of the intrinsic clotting cascade pathway and common pathway in the clotting mechanism.
- Elevated BUN may indicate renal disease or dehydration.
- Serum creatinine measures the amount of creatinine in the blood and is excreted entirely by the kidneys.
- The GFR is the rate at which the glomeruli are filtering blood and is used to determine kidney function.
- Liver function labs include Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP), and Bilirubin.
