Electrolyte Panel with Renal Function and Electrolyte View (Serum/Plasma)

What Is Measured?

Your blood sample will be tested for several important substances, including sodium, potassium, chloride, bicarbonate, creatinine, and possibly other electrolytes or kidney-related markers. Some tests may also check for glucose or other substances depending on the specific panel requested.

Why Is This Test Done?

Doctors order this test to evaluate how well your kidneys are working, check for imbalances in electrolytes, or monitor conditions like heart disease, kidney disease, or dehydration. It helps identify issues that could affect your body’s ability to maintain proper fluid and electrolyte levels.

Common Reasons for Testing

Common reasons include diagnosing kidney problems, managing chronic conditions like high blood pressure or diabetes, checking for dehydration, or monitoring treatment effects. It may also be used before surgeries or during pregnancy.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours if glucose or other specific tests are included. Drink plenty of water the day before if your doctor recommends it. Avoid certain medications or supplements that could affect results.
