Clinical Use:
Background: 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.
Reference Ranges: 22 – 29 mmol/l
Associated Diseases:

Higher than normal levels:

  • Hyperaldosteronism
  • Cushing syndrome

Lower than normal levels:

  • Ketoacidosis
  • Lactic acidosis
  • Kidney disease
  • Addison disease
Patient Preparation:
Specimen Requirements: Sample type:

  • Serum or Lithium Heparin Plasma.

Sample identification:

  • Three patient identifiers from:
    • Name
    • D.O.B.
    • Address
    • N.H.S. number
    • Unit Number

    should match on the specimen and request form. This check may be performed prior to centrifugation by the Central Sort department.

Turnaround Time: 2 hours
