Bicarbonate

Test information: Usually as part of a renal profile , to screen for an electrolyte or acid-base imbalance. Also known as total CO . In metabolic acidosis, bicarbonate is reduced, e.g. in diabetic ketoacidosis. In metabolic alkalosis, it is increased . as in pyloric stenosis or the compensated respiratory acidosis of chronic obstructive airways disease.

Comments

Serum bicarbonate is not a very reliable assay from a clinical point of view, since total CO² is being measured. Arterial blood gas samples provide a more reliable indication of acid/base status.
