Information displayed below is a subset of the entire knowledge base and may be incomplete intensionally or inadvertently. If you detect a serious error or want access to the complete knowledge base, please contact us.


The clinical test for bicarbonate acquired from a patient's serum is a blood test. The test measures the amount of bicarbonate in the blood. Bicarbonate is a type of electrolyte that helps regulate the body's pH balance.

To obtain the bicarbonate level, a sample of the patient's blood is taken and sent to a laboratory for analysis. The laboratory will measure the amount of bicarbonate in the sample using a technique called ion-selective electrode. This technique measures the electrical potential of the bicarbonate ions in the sample. The results of the test will be reported as a numerical value, usually in millimoles per liter (mmol/L).
