A Serum Bicarbonate Test measures the level of bicarbonate (HCO3-) in your blood, which is an essential component of the body’s buffering system that helps maintain acid-base balance.
Bicarbonate acts as a buffer to prevent the blood from becoming too acidic or too alkaline. It plays a crucial role in balancing electrolytes, maintaining proper pH levels in the blood, and facilitating various physiological functions. This test is often conducted as part of an electrolyte panel to assess kidney and lung function, as these organs regulate bicarbonate levels. A normal serum bicarbonate level is crucial for ensuring that the body’s internal environment remains stable.
A normal serum bicarbonate level typically ranges from 22 to 29 milliequivalents per liter (mEq/L) for adults. For children, the range can vary slightly, typically between 20 to 28 mEq/L. These ranges can also differ slightly depending on the laboratory performing the test, but most labs use these as standard values. Maintaining bicarbonate within this range is essential to ensure that the body can neutralize acids and avoid complications related to pH imbalance.
1] Normal Range for Adults: 22–29 mEq/L
2] Normal Range for Children: 20–28 mEq/L
The serum bicarbonate normal value reflects the body’s acid-base status and helps healthcare providers determine if any disturbances are present in the respiratory or metabolic systems.
Low serum bicarbonate levels, known as bicarbonate deficiency or hypobicarbonatemia, occur when the blood becomes too acidic. This condition is often associated with metabolic acidosis, which is characterized by an excess of acid in the body.
A] Chronic kidney disease: Impaired kidney function can result in the accumulation of acids in the body, leading to low bicarbonate levels.
B] Diabetic ketoacidosis (DKA): A serious complication of diabetes, where high blood sugar leads to the buildup of acidic ketones, lowering bicarbonate levels.
C] Lactic acidosis: A condition caused by the buildup of lactic acid in the body, which can lower bicarbonate.
D] Respiratory acidosis: When the lungs cannot remove enough carbon dioxide from the body, causing an acid buildup.
On the other hand, high serum bicarbonate levels can indicate an alkaline imbalance in the blood, known as alkalosis. This condition occurs when there is an excessive amount of bicarbonate or a significant loss of acids from the body.
A] Metabolic alkalosis: Caused by the loss of acids from vomiting or excess bicarbonate from medications, such as antacids.
B] Chronic lung disease: In conditions such as emphysema or chronic obstructive pulmonary disease (COPD), the body may retain carbon dioxide, increasing bicarbonate levels as a compensatory mechanism.
C] Hypokalemia: Low potassium levels in the blood can lead to metabolic alkalosis and elevated bicarbonate.
D] Adrenal disorders: Certain adrenal gland issues can cause an increase in bicarbonate levels.

The risks involved with this test are minimal. You may experience slight discomfort, bruising, or soreness at the site where blood is drawn, but these side effects usually subside quickly.
The test is a simple blood test. A healthcare professional will draw blood from a vein, typically in your arm, and the sample will be analyzed in a laboratory to measure the bicarbonate levels.
Generally, no special preparation is required for the serum bicarbonate test. However, it is always advisable to inform your doctor of any medications or supplements you are taking, as certain drugs may affect the test results.
Several factors can influence bicarbonate levels, including kidney function, respiratory conditions, certain medications (like diuretics), and electrolyte imbalances. It’s important to discuss your results with a healthcare provider to determine the underlying cause.
