What This Test Measures

Your blood sample will be analyzed for sodium, potassium, chloride, bicarbonate, and sometimes calcium or phosphate levels. These electrolytes work together to maintain fluid balance, nerve signaling, and acid-base equilibrium in your body.

Why It’s Done

Doctors may order this test to diagnose or monitor conditions like dehydration, kidney disease, heart problems, or metabolic disorders. It’s also used before surgeries, during pregnancy, or if you’re taking certain medications that affect electrolytes.

When to Expect Results

Results typically arrive within 1–3 business days, depending on your lab. Your doctor will discuss the findings with you during your follow-up visit.

Common Reasons for Testing

Symptoms like excessive thirst, muscle weakness, confusion, or irregular heartbeat may prompt this test. Chronic conditions like heart failure, kidney disease, or diabetes can also require regular monitoring of electrolytes.
