Anion Gap Panel (Electrolyte Balance)
About this panel
A panel of four blood tests measuring electrolyte, acid-base, and water balance, including a calculated anion gap used to help diagnose metabolic acidosis.
Measures sodium, potassium, chloride, and carbon dioxide (bicarbonate) levels, and calculates the anion gap, the difference between serum anion and cation levels, related to acid-base and water balance.
