: What This Test Measures

: The test quantifies the concentration of sodium (an essential electrolyte), digoxin (a medication used for certain heart conditions), and glucose (blood sugar) in a serum sample.

: How the Test Is Performed

: A blood sample is collected from a vein, typically in the arm. The serum is separated and analyzed using an electrophoresis-based method to determine the concentration of each analyte.

: Why Your Doctor May Order This Test

: Your healthcare provider may order this panel to assess electrolyte balance, monitor glucose levels, or check the level of digoxin in your blood to ensure it is within a safe and effective range.

: What to Expect

: You may need to fast before the glucose measurement, depending on your provider's instructions. Tell your doctor about all medications you take, especially digoxin, as timing of the test may need adjustment.
