What This Test Measures

Your blood sample will check for levels of electrolytes like sodium, potassium, chloride, and bicarbonate, which are vital for nerve and muscle function, as well as kidney function. Your doctor may also measure creatinine, a waste product filtered by the kidneys, and possibly other markers like blood urea nitrogen (BUN).

Urine Collection for Kidney Function

A 24-hour urine collection may be required to measure the amount of certain waste products (like creatinine) excreted over a full day. This helps determine how well your kidneys are filtering blood and removing waste.

Why It Matters for ESRD

Kidneys in ESRD may not function properly, leading to imbalances in electrolytes and waste buildup. This test helps your healthcare team monitor these levels to prevent complications like heart rhythm issues, muscle weakness, or fluid imbalances.

What to Expect Before the Test

No special preparation is usually needed for blood tests, but you may be asked to collect urine for 24 hours. Follow your doctor’s instructions carefully to ensure accurate results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How will abnormal results affect my treatment?
Abnormal results may indicate electrolyte imbalances (e.g., too much or too little sodium, potassium, or calcium) or poor kidney function. Your doctor will adjust medications, diet, or fluid intake based on these findings to keep you healthy.
What if I have kidney disease but still have normal lab results?
Even if your blood tests look normal, kidney damage may progress silently. Your doctor may use this panel to detect early signs of imbalance or kidney strain, especially if you have ESRD.
Can I eat or drink anything before the urine collection?
Yes, but collect all urine for 24 hours, including first morning urine. Store urine in a refrigerator and bring the full collection to your appointment to ensure accurate results.
