Renal profile

Renal profile


A renal panel may be a group of tests that will be performed together to gauge kidney (renal) function. The tests measure levels of varied substances, including several minerals, electrolytes, proteins, and glucose (sugar), within the blood to work out the present health of your kidneys. The balance within the body depends on food and fluid intake and excretion by the kidney. Abnormal results are often found in some physiological conditions affecting intake and output, like dehydration and severe diarrhoea. Kidney dysfunction can also end in abnormal electrolyte levels. Medication for hypertension and heart diseases can also affect electrolytes levels.

Electrolytes include:

  • Sodium
  • Potassium
  • Chloride
  • Bicarbonate

About Kidney

The kidneys are a pair of bean-shaped organs located at the rock bottom of the ribcage to the proper and left of the spine. They're a part of the track and perform a couple of essential roles and functions within the body.

Within the kidneys are a few million tiny blood filtering units called nephrons. In each nephron, blood is continually filtered through a cluster of looping blood vessels, called a glomerulus, which allows the passage of water and little molecules but retains blood cells, proteins like albumin, and bigger molecules.

Attached to every glomerulus are tubes (tubules) that have a variety of sections that collect the fluid and molecules that undergo the glomerulus, reabsorb what are often re-used by the body, add other molecules through a process called secretion and, finally, adjust the quantity of water that's eventually eliminated alongside the waste as urine.

Besides eliminating wastes and helping to manage the quantity of water within the body, these activities allow the kidneys to take care of normal analytical balance within the body. Among the important substances, the kidneys help to manage are sodium, potassium, chloride, bicarbonate, calcium, phosphorus, and magnesium. The proper balance of those substances is critical. When the kidneys aren't working properly, the concentrations of those substances within the blood could also be abnormal, and waste products and fluid may build up to dangerous levels within the blood, creating a life-threatening situation.

Kidneys even have a variety of other miscellaneous roles in maintaining a healthy body, including the assembly of a hormone that stimulates red blood corpuscle production (called erythropoietin), production of a hormone that helps maintain a traditional vital sign (called renin), and turning one sort of vitamin D into a more active form, which reinforces calcium absorption.

If the kidneys aren't functioning properly, waste products can accumulate within the blood, and fluid levels can increase to dangerous volumes, causing damage to the body or a potentially life-threatening situation. Numerous conditions and diseases may result in damage to the kidneys and have risk factors for kidney dysfunction, like high vital signs (hypertension), diabetes, disorder, obesity, elevated cholesterol, or a case history of renal disorder.

A healthcare practitioner may order a renal panel when someone has signs and symptoms of the renal disorder, though early renal disorder often doesn't cause any noticeable symptoms. It's going to be initially detected through routine blood or urine testing.

Some common signs and symptoms include:

  • Swelling or puffiness, especially around the eyes or within the face, wrists, stomach, thighs or ankles
  • Urine that's foamy, bloody, or coffee-coloured
  • A decrease in the amount of urine
  • Problems urinating, like a burning feeling or abnormal discharge during urination, or a change within the frequency of urination, especially in the dark
  • Mid-back pain, below the ribs, near where the kidneys are located

Renal profile test involves following tests- Blood Urea Nitrogen, Urea, Creatinine, Phosphorus, Uric Acid, Calcium, Chloride, Potassium, Sodium


Creatinine is that the by-product of phosphocreatine in muscle, and it's produced at a continuing rate by the body. Decreased clearance by the kidney leads to increased blood creatinine. The foremost commonly used endogenous marker for the assessment of glomerular function is creatinine. The calculated clearance of creatinine is employed to supply an indicator of GFR. This involves the gathering of urine over a 24-hour period or preferably over an accurately timed period of 5 to eight hours since 24-hour collections are notoriously unreliable. Improper or incomplete urine collection is one of the main issues affecting the accuracy of this test; hence timed collection is advantageous.

Blood urea nitrogen-

Urea or BUN may be a nitrogen-containing compound formed within the liver because of the outcome of protein metabolism and, therefore, the urea cycle. Urea can also increase in other conditions not associated with renal diseases, like upper GI bleeding, dehydration, catabolic states, and high protein diets. Urea could also be decreased in starvation, a low-protein diet, and severe disease.

The ratio of BUN: creatinine are often useful to differentiate prerenal from renal causes when the BUN is increased. In pre-renal disease, the ratio is on the brink of 20:1, while in intrinsic renal disease, it's closer to 10:1.
