The Carbon Dioxide (CO2) test measures the amount of carbon dioxide in the blood, primarily in the form of bicarbonate. This test is crucial for assessing acid-base balance and respiratory function. CO2 levels reflect the body's ability to maintain pH balance, which is essential for proper cellular function. Abnormal CO2 levels can indicate various conditions, including respiratory disorders, metabolic imbalances, or kidney problems. The test helps diagnose and monitor conditions such as emphysema, chronic obstructive pulmonary disease (COPD), metabolic acidosis, or alkalosis. It's often used in conjunction with other electrolyte tests to provide a comprehensive picture of the body's acid-base status and overall metabolic health.

What do readings below 23 mEq/L for Carbon Dioxide (CO2) - CO2 mean?
A low CO2 level (below 23 mEq/L) may indicate:
-
Metabolic acidosis: A condition where the body produces too much acid or cannot remove it effectively.
-
Respiratory alkalosis: Overbreathing or hyperventilation, leading to excessive loss of CO2.
-
Kidney problems: Inability to retain bicarbonate.
-
Severe diarrhea or dehydration: Leading to loss of bicarbonate.
-
Diabetic ketoacidosis: A complication of diabetes.
-
Lactic acidosis: Buildup of lactic acid in the body.
Low CO2 levels may require further testing to determine the underlying cause and appropriate treatment.
What do readings above 29 mEq/L for Carbon Dioxide (CO2) - CO2 mean?
A high CO2 level (above 29 mEq/L) may indicate:
-
Metabolic alkalosis: A condition where the body has too much base (alkali).
-
Respiratory acidosis: Decreased lung function or airway obstruction, leading to CO2 retention.
-
Cushing’s syndrome: An endocrine disorder causing hormonal imbalance.
-
Chronic vomiting: Resulting in loss of stomach acid and relative increase in bicarbonate.
-
Certain medications: Such as diuretics or corticosteroids.
-
Compensatory response to chronic respiratory acidosis.
High CO2 levels may require further evaluation to identify the underlying cause and determine appropriate management.
