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
Balanced bicarbonate levels help maintain a stable blood pH. A bicarbonate blood test can give insight into how your body manages acids. A low result may be associated with health problems such as chronic kidney disease or metabolic acidosis, while a high result may relate to other conditions. Other electrolytes such as sodium, potassium and chloride, and the kidney markers creatinine and eGFR, give a fuller picture together. Discuss your results with your healthcare provider for interpretation.
When to Test
A bicarbonate blood test is often included in a basic metabolic panel. Some people also choose to check it if they notice symptoms such as prolonged vomiting, difficulty breathing, or unexplained fatigue.

Lifestyle Tips
Staying well-hydrated and eating a balanced diet with plenty of fruits and vegetables can support general metabolic health. Some people find that a mix of plant based proteins alongside other foods suits them. If you have kidney conditions or take medications that affect electrolyte balance, your healthcare provider can advise on monitoring bicarbonate levels.
