Study Notes

Liver Function Tests (LFT)

LFT values include Ca2+, AST, ALT, AlkPhos, Bilirubin, Albumin, and Protein.
Bilirubin indicates liver function and is produced from the breakdown of old RBCs.

Hemoglobin and Hematocrit

Hemoglobin levels: M 13.5-17.5, F 12-16 g/dL.
Hematocrit: M 39-49%, F 35-45%; measures the proportion of RBCs in blood.

Electrolytes

Calcium (Ca++): 8.4-10.2 mg/dL; crucial for nerve function, muscle contraction, blood clotting, and heart operations.
Sodium (Na+): 135-145 mEq/L; key in fluid balance and nerve signals.
Potassium (K+): 3.5-5 mEq/L; vital for heart and muscle function.
Chloride (Cl-): 95-105; maintains fluid balance in conjunction with other electrolytes.
Magnesium (Mg++): 1.6-2.4 mEq/L; supports numerous biochemical reactions in the body.
Phosphate: 2.5-4.5 mg/dL; important for bone health and energy metabolism.

Kidney Function

Blood Urea Nitrogen (BUN): 7-18; assesses kidney and liver health.
Creatinine (Cr): 0.5-1.0 mg/dL; reflects kidney function; elevated levels suggest poor filtration.
BUN/Creatinine ratio: Normal is 10:1 to 20:1; increases may indicate reduced blood flow to kidneys.

Blood Gases and pH Levels

pH: 7.35-7.45; reflects acid-base balance.
Carbon Dioxide (CO2): 35-45; involved in respiratory efficiency.
Bicarbonate (HCO3-): 22-26; indicates metabolic state.
Partial pressure of oxygen (PaO2): 80-100; gauges oxygen delivery.
Oxygen saturation (O2 sat %): 95-100; measures blood oxygen levels.

Coagulation Profile

Prothrombin Time (PT): Normal 9-16 seconds; greater than 30 seconds may indicate bleeding risk.
Partial Thromboplastin Time (PTT): Normal 17-29 seconds; over 90 seconds heightens hemorrhage risk.
International Normalized Ratio (INR): 2-3 for standard warfarin therapy; 3-4.5 for high doses.
Increased aPTT is monitored during heparin therapy.

White Blood Cells (WBC)

WBCs: 4.5k-11k; crucial for immune response and inflammation regulation.

Other Relevant Metrics

Platelets (Plts): 150-450k; essential for clotting.
Ammonia: 10-80 mcg/dL; elevated levels suggest liver dysfunction.
Specific Gravity (SG): 1.005-1.025; with high levels, fluid replacement is necessary.
Erythrocyte Sedimentation Rate (ESR): 0-30 mm/hr; detects overall inflammation and illness.
