The anion gap is essential in understanding electrolyte balance and acid-base homeostasis. To use this calculator, input your lab results for Serum Sodium, Serum Potassium, CO2 (bicarbonate), and Serum Chloride. Our calculator will compute the anion gap using the formula (Serum Sodium + Serum Potassium) - (CO2 + Serum Chloride). This tool is valuable for healthcare professionals and patients aiming to monitor and interpret their electrolyte and acid-base status. It provides a straightforward and reliable way to gain insights into the body's biochemical balance, aiding in informed health management.
