Bicarbonate concentration is measured as part of the electrolyte profile on the Advia analysers. The results obtained are not identical to those from a blood gas analyser since they include dissolved CO2, carbonic acid and carbamine compounds, but differ by approximately 3 mmol/L. Measurement of bicarbonate is of clinical use as a measure of acid-base balance in the bloodstream.
