About this biomarker
Bicarbonate, often reported as CO2 on chemistry panels, helps buffer acids in the body. It is used to assess metabolic acid-base patterns.
Why it matters
It adds context to kidney function, breathing-related issues, and acid-base balance.
What lower levels may suggest
Low bicarbonate may suggest metabolic acidosis or compensation for certain breathing disorders.
What higher levels may suggest
High bicarbonate may suggest metabolic alkalosis or compensation for chronic breathing-related acid-base changes.
Common tests
Basic metabolic panel, comprehensive metabolic panel, electrolyte panel, arterial blood gas
