Bicarbonate blood test: what a low bicarb result may mean

As we age, the kidneys' ability to regulate acid-base balance may change. Monitoring bicarbonate can help ensure metabolic stability and support overall well-being in later years.

Results within 4–6 working days after your blood draw (estimate)

What It Measures

This test measures the level of bicarbonate (CO2) in your blood. It reflects your body's ability to regulate acid-base balance and is often included in a basic metabolic panel.

Why It Matters

Proper bicarbonate levels are essential for maintaining blood pH. Imbalances may indicate respiratory or metabolic conditions and can affect organ function. Consult your healthcare provider for interpretation of your results.

When to Test

Testing may be recommended as part of a routine metabolic panel, or if you experience symptoms such as prolonged vomiting, difficulty breathing, or unexplained fatigue.

Symptoms

Low Levels

Symptoms of low bicarbonate may include rapid breathing, fatigue, confusion, and headache. This condition, known as metabolic acidosis, requires medical attention.

High Levels

High bicarbonate levels may cause muscle twitching, hand tremors, nausea, and confusion. This may be associated with metabolic alkalosis and should be evaluated by a healthcare provider.

Lifestyle Tips

Stay well-hydrated and maintain a balanced diet. If you have kidney conditions or take medications affecting electrolyte balance, work closely with your healthcare provider to monitor bicarbonate levels.

Frequently Asked Questions

What causes low bicarbonate levels?
Low levels may be caused by kidney disease, diabetic ketoacidosis, severe diarrhoea, or certain medications. Your healthcare provider can help determine the underlying cause.
Is bicarbonate the same as baking soda?
Sodium bicarbonate is the chemical name for baking soda. However, blood bicarbonate levels reflect your body's acid-base balance and are different from dietary sodium bicarbonate intake.
How is bicarbonate related to kidney function?
The kidneys play a major role in regulating bicarbonate levels. Abnormal levels may indicate kidney function changes. Discuss your results with your healthcare provider.
