Kidney Panel

Kidney Panel (Electrolyte Status & Enzymatic & Glucid Status & Degradation Products)

Why Get Tested?

To help diagnose and manage conditions that affect kidney function; can be used as part of a general health check or to check on someone who is at risk of developing kidney disease, or to follow up with someone with known kidney disease.

When to be tested?

When you have signs and symptoms that suggest you may have a condition that affects kidney function; when you are being treated for kidney disease; when you have certain risk factors for kidney disease, such as high blood pressure or diabetes.

Champion required?
A blood sample drawn from a vein in the arm.

Do you need test preparation?

You can be instructed to fast for 8-12 hours (no food, only water) before the test.

A renal panel is a set of tests that can be performed together to assess kidney (kidney) function. Tests measure the levels of various substances, including certain minerals, electrolytes, proteins, and glucose (sugar), in the blood to determine the actual health of your kidneys.

The kidneys are located at the bottom of the ribs on the right and left of the spine. They are part of the urinary tract and perform several essential roles and functions within the body.

Inside the kidneys are about a million tiny blood-filtering units called nephrons. In each nephron, blood is constantly filtered through a group of blood vessels called the glomerulus, which allows water and small molecules to pass through but stores blood cells, proteins such as albumin, and larger molecules.

Attached to each glomerulus are tubes that have a number of sections that collect fluid and molecules that pass through the glomerulus, reabsorb what can be used back by the body, add other molecules through a process called secretion, and finally adjust the amount of water that is eventually eliminated along with waste such as urine.

In addition to eliminating waste and helping to regulate the amount of water in the body, these activities allow the kidneys to maintain a normal chemical balance in the body. Among the important substances that the kidneys help regulate are sodium, potassium, chloride, bicarbonate, calcium, phosphorus, and magnesium. The proper balance of these substances is critical. When the kidneys are not working properly, the concentration of these substances in the blood can be abnormal and waste products and fluid can build up to dangerous levels in the blood, creating a life-threatening situation.


  • Minerals
  • Phosphorus – a mineral that is vital for energy production, muscle and nerve function, and bone growth; it also plays an important role as a buffer, helping to maintain the body’s acid-base balance.
  • Calcium – one of the most important minerals in the body; is essential for the proper functioning of muscles, nerves, and heart and is required in blood clotting and bone formation.
  • Protein
  • Albumin – a protein that makes up about 60% of the protein in the blood and has many roles such as retaining blood flow from blood vessels and transporting hormones, vitamins, drugs, and ions such as calcium throughout the body.

Waste products

(BUN) – urea is a nitrogen-containing waste product formed by protein metabolism; released from the liver into the blood and carried to the kidneys, where it is filtered by the blood and eliminated in the urine.

Creatinine – another waste product produced by the muscles of the body; almost all creatinine is eliminated by the kidneys.

Energy source

Glucose – supplies energy to the body; a stable amount should be available for use, and a relatively constant glucose level should be maintained in the blood.

Three calculated values ​​can also be reported with a renal panel:

  • The ratio of urea (BUN) / Creatinine – a comparison of urea (nitrogen) with the creatinine content in the blood.
  • Estimated glomerular filtration rate (eGFR) – a calculated estimate of the actual glomerular filtration rate (GFR, the amount of blood filtered by the glomerulus to the kidneys per minute) derived from the level of creatinine in the blood; the formula takes into account the age, gender, race and sometimes height and weight of the person.
