Kidney (Renal) Function Test Panel in Louisiana

What this test is

The Kidney Function Test Panel is a group of tests that evaluate how well your kidneys are functioning. It measures different substances in the blood that indicate kidney health. This panel helps in understanding the kidneys' ability to filter waste and manage electrolytes.

What it measures

• Creatinine — reflects kidney filtration efficiency
• Blood Urea Nitrogen (BUN) — indicates waste removal capability
• Glomerular Filtration Rate (GFR) — estimates overall kidney function
• Electrolytes — assess balance of minerals like sodium and potassium
• Albumin — checks protein levels for kidney damage
• Phosphorus — evaluates mineral balance affected by kidney function

What the test involves

The test involves a standard blood draw, where a sample is taken from a vein in your arm. The sample is then analyzed in a laboratory to measure various markers.

Why it is often ordered

Clinicians typically order this test to monitor kidney health or diagnose potential kidney-related issues. It is also used to track changes in kidney function over time, especially in individuals with conditions affecting the kidneys.

Preparation

Preparation instructions may vary, so it's important to follow the specific guidelines provided by the laboratory. This may include fasting or avoiding certain medications.

How results are reported

Results are reported based on the levels of different substances in the blood, with reference ranges that vary by laboratory. The interpretation of these results should be done by a healthcare provider.

Before you go

• Check if fasting is required.
• Verify the lab's sample collection hours.
• Ask about any medication restrictions.
