A bicarbonate test is a routine blood check that measures the amount of carbon dioxide in your body, mostly in the form of bicarbonate. This test helps doctors evaluate your electrolyte balance and acid-base status. Bicarbonate acts as an essential buffer, keeping your blood pH stable so your vital organs can function correctly.
Abnormal levels can signal underlying health issues like kidney disease, breathing disorders, or severe dehydration. Doctors frequently order this test as part of a basic metabolic panel to monitor your overall metabolic health and internal chemical balance.
