Bicarbonate levels are almost always done with other electrolytes to tell whether sodium, potassium, chloride, and bicarbonate levels are in balance. They may be measured as part of routine blood testing, or when an imbalance is suspected. Bicarbonate may also be measured when evaluating acid-base balance, to screen for an imbalance, and to monitor a known problem during treatment.
