Study Notes

Serum Electrolytes

Essential blood test measuring key electrolytes in the body.
Main electrolytes include sodium, potassium, calcium, chloride, magnesium, phosphorus.

Sodium

Normal range: 135-145 mEq/L.
Crucial for fluid balance, nerve transmission, and muscle function.

Potassium

Normal range: 3.5-5.5 mEq/L.
Vital for heart function, muscle contraction, and nerve signaling.

Calcium

Normal range: 8.5-10.9 mg/L.
Important for bone health, muscle function, and blood clotting.

Chloride

Normal range: 95-105 mEq/L.
Assists in maintaining fluid balance and acid-base balance.

Magnesium

Normal range: 1.5-2.5 mEq/L.
Plays a role in muscle and nerve function, and energy production.

Phosphorus

Normal range: 2.5-4.5 mg/dL.
Involved in energy storage, bone health, and cellular function.

Hematology

The study of blood components, including red blood cells (RBC), white blood cells (WBC), platelets (Plt), and hemoglobin (Hgb).

Red Blood Cells (RBC)

Normal range: 4.5-5.0 million cells per microliter.
Responsible for transporting oxygen throughout the body.

White Blood Cells (WBC)

Normal range: 5,000-10,000 cells per microliter.
Key role in immune defense against infections.

Platelet Count (Plt)

Normal range: 200,000-400,000 cells per microliter.
Crucial for blood clotting and wound healing.

Hemoglobin (Hgb) for Women

Normal range: 12-16 g/dL.
Protein in RBC that carries oxygen.

Hemoglobin (Hgb) for Men

Normal range: 14-18 g/dL.
Essential for oxygen delivery to tissues.

Arterial Blood Gas (ABG) Values

Critical for assessing respiratory and metabolic functions.

HCO3 (Bicarbonate)

Normal range: 24-26 mEq/L.
Important for maintaining pH balance in the body.

CO2 (Carbon Dioxide)

Normal range: 35-45 mEq/L.
Indicates respiratory function and metabolic rate.

PaO2 (Partial Pressure of Oxygen)

Normal range: 80%-100%.
Reflects the amount of oxygen dissolved in blood.

SaO2 (Oxygen Saturation)

Normal threshold: greater than 95%.
Percentage of hemoglobin saturated with oxygen.

Glucose

Normal range: 70-110 mg/dL.
Main energy source for the body; monitoring is essential for diabetes management.

Specific Gravity

Normal range: 1.010-1.030.
Indicates kidney function and hydration status through urine concentration.

Blood Urea Nitrogen (BUN)

Normal range: 7-22 mg/dL.
Provides information on kidney function and protein metabolism.

Serum Creatinine

Normal range: 0.6-1.35 mg/dL.
Measurement of kidney function and muscle metabolism.
