What Is a Creatinine Test and Why Is It Important for Kidney Health?

What is creatinine?

Creatinine is a metabolic waste product that is excreted by the kidneys. It is a by-product of the body's breakdown of muscle tissue. It is estimated in milligrams per deciliters of blood.

When its levels are high, it may be a sign of renal disease or an inherited disorder. If you can sense the symptoms, take a creatinine serum test after consulting your doctor.  In this article, we'll explore what a creatinine test is, why it is important for kidney health, and how it can help identify potential issues early on.

Interpreting Creatinine Levels

Understanding what different creatinine levels signify is essential for both patients and healthcare providers.

Normal Creatinine Levels: Normal creatinine levels typically range from 0.84 to 1.21 mg/dL for adult males and 0.71 to 1.05 mg/dL for adult females. Keep in mind that these values can vary slightly between laboratories.

Elevated Creatinine Levels: Elevated creatinine levels may indicate kidney dysfunction. The degree of elevation can provide insights into the severity of the issue. Mild increases may suggest early kidney damage, while significant elevations may indicate more advanced kidney disease.

Decreased Creatinine Levels: While less common, low creatinine levels may also raise concerns. This can occur in conditions of muscle loss or decreased muscle mass. In some cases, it may reflect a problem with muscle function.

Causes of increased creatinine levels

Kidney infection 

Numerous factors, including exposure to specific pathogens, developing cancer, or having a compromised immune system, can lead to kidney infection. High blood creatinine levels may result from it. The kidneys are in charge of eliminating waste from the body, and when they are infected, they cannot do this efficiently. It will excrete this metabolic waste into the blood, and a blood test at home  can identify its rise. 

Glomerulonephritis ( GN)

Glomerulonephritis is a collection of disease processes that occur when part of the kidney becomes inflamed, leading to damaged tissue and the loss of kidney function is characterized by the presence of blood cells in urine or a protein called proteinuria in the urine. 

Glomerular diseases can make you feel: feverish, have abdominal pain, have difficulty urinating, or have blood in your urine. Over time, the kidney cannot carry out its duty and cannot excrete toxins in urine but mix it in blood. 

Kidney stone 

Although stones can develop everywhere in the kidney, the ureter is where they most frequently occur. Over time, urine and other chemicals might accumulate, which can cause the stone to become trapped. 

A kidney stone is a mineral clump composed of calcium and other elements that develop in one or both kidneys. If the stone is large enough to obstruct urine flow, it can cause the blood level of the metabolic waste to rise.

Effects of high creatinine levels 

Rhabdomyolysis

Any person with undesirable metabolic waste levels can be susceptible to the medical emergency of rhabdomyolysis. The body's muscle cells begin to degrade during this process. This may result in kidney damage, severe exhaustion, and muscle weakness. 

A protein called myoglobin may be released out of control due to the uncommon but dangerous disorder rhabdomyolysis. Sometimes, it can also lead to organ failure and death.

Compartment syndrome 

Any muscle or tendon in the body may be afflicted by compartment syndrome. It is brought on by pressure on the area where the muscles and skin meet. This may occur if the kidneys aren't functioning correctly and too much fluid accumulates in the tissues.

Dehydration

Dehydration is a common summer problem and can lead to many health problems. People often don’t realize how much water they drink and end up dehydrated. 

When people are dehydrated, their bodies can’t function as well as they should. This can cause many problems, including headaches, sleeplessness, and seizures. s However, not everyone is affected by dehydration because of hyper creatinine levels.

Thus, these are some fundamentals to know about the creatinine levels in the body. If you doubt your renal health or are experiencing any of the causes mentioned above, take a creatinine serum test. Acting immediately can help you not to reach ill effects. Do not procrastinate when it comes to your health under any circumstance.
