Bicarbonate, Serum

Bicarbonate, Serum Test

The Bicarbonate, Serum test measures the level of bicarbonate (HCO₃⁻) in the blood. Bicarbonate is an important electrolyte that helps maintain the body’s acid-base (pH) balance. This test is commonly used to evaluate metabolic and respiratory conditions, kidney function, and electrolyte balance.

Why is the Bicarbonate, Serum Test Done?

Doctors may recommend this test to:

• Assess acid-base balance in the body
• Diagnose metabolic acidosis or alkalosis
• Monitor kidney and lung disorders
• Evaluate dehydration or electrolyte imbalance
• Monitor treatment in critically ill patients
• Investigate symptoms such as confusion, weakness, vomiting, or breathing problems

Symptoms That May Require Testing

• Shortness of breath
• Fatigue or weakness
• Confusion
• Persistent vomiting or diarrhea
• Rapid breathing
• Muscle twitching or cramps

Normal Reference Range

Typical bicarbonate levels in adults are:

• 22 – 29 mEq/L

Reference ranges may vary slightly depending on the laboratory and testing method.

What Do Abnormal Results Mean?

Low Bicarbonate Levels

May indicate:

• Metabolic acidosis
• Kidney disease
• Diabetic ketoacidosis
• Severe diarrhea
• Lactic acidosis
• Shock or severe infection

High Bicarbonate Levels

May indicate:

• Metabolic alkalosis
• Chronic lung disease
• Excessive vomiting
• Dehydration
• Use of certain diuretics

Sample Required

• Sample Type: Serum
• Preparation: Usually no fasting required unless advised by the doctor
