Bicarbonate / CO2

A metabolic-panel acid-base signal connected to kidney, lung, metabolism, and electrolyte context.

What it is

Bicarbonate or total CO2 in a chemistry panel reflects acid-base buffer context.[1,2,3]

Why it matters

It links kidney acid handling, lung carbon dioxide physiology, metabolism, and electrolyte balance.[1,2,3]

What it affects

  • It is a bridge between metabolic panels and blood gas context.[1,2,3]
  • It can sit downstream of several disturbances rather than one cause.[1,2,3]

Interpretation traps

  • Chemistry CO2 and arterial blood gas measures are not identical contexts.[1,2,3]
  • BioConst does not interpret acid-base disorders.[1,2,3]
