Kidney Health Tests in Puerto Rico

What this test is

This panel is a group of laboratory tests that evaluate kidney function and detect potential issues. It measures various substances in your blood and urine to understand how efficiently your kidneys are filtering waste products.

What it measures

• Blood Urea Nitrogen (BUN) — reflects kidney function and hydration status
• Creatinine — a waste product filtered by the kidneys
• Estimated Glomerular Filtration Rate (eGFR) — calculates kidney filtration capacity
• Albumin-to-Creatinine Ratio (ACR) — checks for protein in the urine, an early sign of kidney damage
• Electrolytes (Sodium, Potassium, Chloride, CO2) — assess fluid and electrolyte balance

What the test involves

A sample is typically collected through a standard blood draw from a vein in your arm. In some cases, a urine sample may also be required.

Why it is often ordered

Clinicians often order kidney health tests to monitor for or diagnose kidney disease, especially in individuals with risk factors like diabetes or high blood pressure. They can also be used to track the effectiveness of treatments for kidney conditions.
