This blood test measures the level of bicarbonate, a form of carbon dioxide dissolved in the blood that helps keep the body's acid-base balance in a healthy range. It's a routine part of a basic metabolic panel and helps evaluate kidney function, breathing problems, and overall chemical balance in the blood. An abnormal result can point to a range of issues, from dehydration to a lung or kidney condition.
