The Bicarbonate Test is a crucial measure of your body's acid-base (pH) balance. Bicarbonate is a key electrolyte that acts as a buffer, keeping your blood from becoming too acidic or too alkaline. This test, part of our Serum Electrolytes panel, is essential for investigating and monitoring conditions that affect your metabolic function, including kidney disease or lung disorders. A simple blood draw is all that is required. This is a foundational check, providing vital insight into your body's core chemical balance and ensuring its fundamental systems are in perfect harmony.
