Creatinine Urine Test: What Is the Normal Range?

September 12, 2019

It is very important to take care of one’s kidneys, without the kidneys the body may fail after a time. Usually, tests are conducted to see how the kidneys are doing; and these tests are even more common to people who have kidney problems. One specific test that is normally used for kidney disease patients is the creatinine test. It measures the amount of creatinine in the body to determine the current condition of the kidney depending on the result.

This article will be an in-depth discussion about the measurement of creatinine in the kidneys and what it may be an indicator of.


Chronic Kidney Disease: All You Need To Know

Unfortunately, the kidneys have their limits. A single mistake, which mainly relies on an individual’s diet, may highly affect the functioning of the kidneys. After the organ gets severely damaged, that is when it will start to have problems with its functions and this results in a serious condition called chronic kidney disease or kidney failure.

Based on the name of the disease, it is a major malfunction of the kidneys. This kind of disease usually occurs gradually and as time goes by there is a possibility that the organ may completely stop working. Conditions like this are really dangerous, considering how responsible the kidneys are when it comes to the filtering of waste materials in the body. Can you even imagine what will happen once the kidneys are unable to function?

The waste materials and toxins that should be excreted through urine are left in the body. They will get accumulated in the body (it is even more dangerous since it mostly gathers in the blood) and they will become more poisonous as time goes by. So far, those who reach the advanced stage of the disease encounter the buildup of hazardous fluids and other wastes that may lead to more serious complications; and even death.



Chronic kidney disease is not easily diagnosed. During its early stage, there may be a few symptoms that the affected individual will encounter; but it is only when the condition completely takes over the kidneys by making the organ significantly disable when the disease can finally be diagnosed to be existent.

The disease can somehow be managed by treatments that focus on decreasing the development of its damage to the kidney, and this happens by taking charge of whichever caused the damage to the organ. However, the late stages of the disease are harder to manage as it will need more specific methods in keeping the kidneys alive. The best ways are to either undergo a series of hemodialysis or by having a kidney transplant.


Symptoms of Chronic Kidney Disease

There may be some indications during the early stages of the disease. Still, these symptoms must be monitored in case they may be pointing to the occurrence of the disease.

  • Frequent nauseous feeling
  • Unusual vomiting that happens without warning
  • A sudden loss of appetite
  • Lethargy and feeling weak
  • Recurring sleeping issues
  • Uncontrollable urination pattern
  • Compromised mental alertness and sharpness
  • Cramps
  • Swelling of the feet and ankles
  • Skin itching
  • Chest pains or a heartburn sensation
  • Difficulty of breathing
  • High blood pressure

It is hard to confirm if the mentioned symptoms point to chronic kidney disease. This is why it is important to ask for some advice from a medical professional and for them to be able to conduct necessary tests to check the real cause of the symptoms.


What Causes Chronic Kidney Disease?

The kidneys do not get damaged without any reason. Normally, it is another disease or health condition that causes severe damage to the organ. It may be more dangerous if the person has more than one condition that can affect the kidneys. This might speed up the damage and may lead to the complete shutdown of the organ. If you have one (or more) of these health issues for a long time, you may want to get your kidneys checked by undergoing different blood and urine tests like creatinine test.

  • High blood pressure or hypertension: This is a common non-kidney related health condition that causes further damage to the kidneys. Even taking medications for hypertension may contribute to the damage, which makes it important to manage this condition well.
  • Glomerulonephritis: A condition where the filtering units of the kidney becomes inflamed.
  • Vesicoureteral reflux: Similar to acid reflux but it occurs in the urinary tract and it is the urine that gets stuck instead of acid. The person with this kind of condition may only experience a few urine excretions since the urine tends to get back to the kidneys no matter the attempt of getting it out.
  • Many other kidney issues: It may also be interstitial nephritis, polycystic kidney disease, pyelonephritis, kidney stones, and many others.


Creatinine Urine Test

Creatinine is a waste product and it is very harmful when it accumulates at high levels.  High amounts of creatinine indicate a possible problem of the kidneys which may normally be a case of chronic kidney disease.

What Is The Normal Range of Creatinine?

To determine if someone has kidney problems, there is a range that is being followed. The range may vary depending on the age and weight of the individual, but usually, they follow the urine creatinine normal range of 123.8 to 229.8 µmol/kg/day for men and 97.2 to 176.8 µmol/kg/day for women. Men have higher creatinine levels because of their body mass which tends to be higher than women in general.
