C-Peptide: What Does the C-Peptide Index Say About Your Pancreas?
C-peptide is a substance your pancreas produces alongside insulin. The C-peptide index helps assess how much insulin your pancreas produces on its own. This can be useful when investigating diabetes or insulin resistance. As you age, insulin production may change. Your doctor can evaluate the C-peptide value alongside your glucose and insulin results.

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.
