What is Bicarbonate (Bicarbonate)?

Bicarbonate is measured as part of a electrolytes panel. Your bicarbonate is normal — acid-base balance is maintained.

What does a high Bicarbonate mean?

High bicarbonate suggests metabolic alkalosis. Common causes include vomiting, diuretics, or excessive antacid use.

What does a low Bicarbonate mean?

Low bicarbonate suggests metabolic acidosis — your blood may be more acidic than normal. Can be caused by kidney disease, diarrhea, or diabetic ketoacidosis.

Understand your whole report, not just one number

A single value rarely tells the full story — Bicarbonate is best read alongside the rest of your panel. Paste your values or upload your report and get a plain-English explanation of every marker, with the important results flagged.
