  • Diabetic nephropathya glomerular disease caused by kidney damage due to diabetes. Its the most common type of kidney disease in the U.S. and often leads to kidney failure.
  • Glomerular disease or glomerulonephritisdamage to the filtering structures in the kidney caused by inflammation. It may run in your family or be caused by an immune disorder or infection. Its the second most common type of kidney disease in the U.S. and often leads to kidney failure.
  • Acute kidney injury a sudden illness of the kidneys resulting from one of many causes. AKI may result from an injury that damages the kidneys or a lack of blood flow to the kidneys. It can also occur if urine is blocked from leaving the kidneys by something such as an enlarged prostate or kidney stones. The buildup of toxins and pressure can then cause kidney damage, which may lead to acute kidney failure.
  • Polycystic kidney disease an inherited disease in which cysts form in the kidneys. PKD may eventually lead to kidney failure.
  • Nephrotic syndromea condition resulting from glomerular disease thats caused by excess protein in your urine due to damage to the filtering structures in the kidney . Nephrotic syndrome can lead to high blood pressure and is a significant signal that your kidneys are not working well.
  • Lupus nephritisa condition caused by the autoimmune disease lupus, which results in kidney damage and scarring. Lupus nephritis can lead to CKD and eventually ESRD.

Can A Low Protein Intake Cause A Low Bun Ratio

On the other hand, a low protein intake may lead to an abnormally low level of BUN. If you are going to undertake a BUN creatinine ratio test, make sure that you consume a normal amount of protein and that you are properly hydrated. That way, you will be able to come up with an accurate BUN creatinine ratio test result.

Can A High Creatinine Level Be A Sign Of Kidney Disease

Elevated creatinine levels can be the first sign of kidney disease. Unfortunately, by the time elevated creatinine levels have been detected, a substantial amount of kidney function can already have been lost. The major causes of increased creatinine levels are the same as the major causes of kidney disease high blood pressure and diabetes.

What Happens If I Forget To Collect One Urine Sample During Collection

Its very important to collect urine samples throughout the entire day for the creatinine clearance test to be accurate. If you skip one urine collection, it could affect the test results. Call your healthcare providers office if you miss a collection to see if you should continue the test or stop and start over the next day.

Blood Tests That Measure Diabetes Control

How to bring down or reduce high creatinine levels ...


A blood glucose test measures the amount of a type of sugar in your blood. Glucose is your blood sugar. It is measured to make sure your body is able to digest and utilize sugar and carbohydrates correctly. If your blood sugar is too high, it may mean you have diabetes.

Normal Fasting Glucose levels:

  • No known diabetes: less than 100 mg/dl
  • Above 125 mg/dl can indicate diabetes
  • Diabetics: 70-130 mg/dl is within target range

Normal Non-fasting

  • No known diabetes: less than 140 mg/dl
  • Diabetics: less than 180 mg/dl

Hemoglobin A1C

A glycosylated hemoglobin A1C reading reveals your average blood glucose level over the past three months and can be used to monitor your diabetic control and to predict your risk for diabetic complications. How does it do that? Your body actually memorizes the trail that sugar leaves in your body. When blood glucose is high, the sugar molecules attach themselves to red blood cells. The red blood cells store the sugar information for about four months. A blood test can then retrieve your average blood glucose results in the format of a percentage. The greater your A1C value, the higher your risk for diabetic complications. For the diabetic with CKD, good control of your blood sugar can slow the worsening of kidney function. Ask your doctor what your result should be. For most people, the result should be less than 7%.

What Do High Creatinine Levels Mean

Creatinine is a waste product that is produced by your muscles. It is typically removed through the kidneys. Healthy kidneys filter creatinine out of your blood, and it leaves your body through urine. Your doctors can measure the amount of creatinine in your blood and in your urine to get an idea of how well your kidneys are working. This measurement is called creatinine clearance. Having high creatinine levels probably isnt harmful on its own, though it can be a marker of other health conditionsincluding chronic kidney disease . A serum creatinine blood test, along with factors such as age, weight, and medical history, can help doctors understand how well your kidneys are functioning and whether there may be an issue.

Causes Of High Creatinine

Causes listed below are commonly associated with high creatinine. Work with your doctor or another health care professional to get an accurate diagnosis. Your doctor will interpret this test, taking into account your medical history and other tests. A result that is slightly higher may not be of medical significance, as this test often varies from day to day and from person to person.

1) Kidney Disease

Creatinine is most commonly checked to measure kidney function. If creatinine is high, it may indicate kidney disease or impaired kidney function .

Diabetes can cause injury in the blood vessels of the kidneys which in turn reduces the ability of the kidneys to filter the blood from waste products including creatinine .

2) Diet High in Protein

Studies have found that a protein-rich diet elevates the levels of blood creatinine both in healthy and individuals suffering from kidney failure .

Also, eating cooked meat just before the test can cause a spike in creatinine levels. This happens because cooking converts the creatine present in meat into creatinine .

3) Exercise

Exercise can increase creatinine short-term, due to muscle damage, or long-term, due to an increase in muscle mass .

Studies in healthy individuals show a direct correlation between muscle mass and the levels of blood creatinine. This correlation is significant for both adult men and women .

4) Creatine Supplements

What Are The Causes Of High Creatinine Levels

High creatinine levels may be caused due to following reasons

Chronic Kidney Diseases

Chronic kidney disease may lead to an increased level of serum creatinine. Based on increased creatinine levels, the doctor may advise undergoing eGFR for confirming chronic kidney disease.

Increased Protein Intake

High protein intake such as protein supplements or cooked meat increase the level of creatinine.


Dehydration increases serum creatinine levels. In case of severe dehydration, the kidney may experience acute injury and the patient may need dialysis.

Kidney Obstruction

Hydronephrosis, a condition characterized by urine accumulation and reduced kidney function, caused by kidney stones or Benign Prostate Hyperplasia, may result in an increased level of serum creatinine.


Certain medications may also lead to the rise of serum creatinine levels. These medications include trimethoprim/sulfamethoxazole, cimetidine, ranitidine, fenofibrate, and cephalosporin antibiotic.

Rigorous Exercise

Rigorous exercise may also lead to an increase in serum creatinine levels.

At What Level Of Creatinine Dialysis Is Required

How increased creatinine level affects kidneys?

Although high creatinine levels may indicate a kidney problem particular creatinine level is not an indicator for initiation of dialysis. The initiation of dialysis is done based on the results of the estimated Glomerular Filtration Rate. The decision also includes various factors such as the age of the patient, level of kidney function, and the symptoms experienced by the patient. It is the collective decision made by nephrologist, patient, and his relatives.

Which Is More Accurate Urea Or Creatinine Blood Test

Creatinine is a waste product made by the muscles. Creatinine passes into the bloodstream and is usually passed out in urine. A high blood level of creatinine indicates that the kidneys may not be working properly. Creatinine is usually a more accurate marker of kidney function than urea. The effect of muscle mass needs to be taken into account.

What Else Can You Do To Protect Your Kidney Function And Prevent Kidney Damage

  • Get your kidneys checked at least every year. Your healthcare team will do a simple blood test to find out your eGFR. They will also do a urine albumin-creatinine ratio , which shows if you have protein in the urine. Protein in the urine may mean you have kidney damage.
  • Control blood pressure if you have high blood pressure.
  • Control blood sugar if you have diabetes.
  • In general, if you have CKD, avoid non-steroidal anti-inflammatory drugs such as ibuprofen and naproxen.
  • If you have CKD, tell your healthcare team before having any test that uses contrast dye.
  • Do not smoke.
  • Exercise and follow a healthy diet that’s low in sodium, saturated fat, and sugar, but high in fresh fruits, vegetables, whole grains, lean meats, fish, and poultry. Avoid highly processed foods.
  • Stay at a healthy weight. Lose weight if your healthcare team says that you should.
  • Discuss any vitamins, minerals, herbs, weight loss or body building supplements with your healthcare team before taking them. Many of these products can hurt your kidneys.
  • Make sure that any drugs you take are the right dose for your age and your level of kidney function. You should discuss this with your healthcare team.

Don’t Miss: What Std Messes With Your Kidneys

Creatinine Levels In Urine

According to the University of Maryland Medical Center, the normal range of creatinine in a 24-hour urine sample is 500 to 2,000 mg a day. Since it is the breakdown of creatine which is sent to the kidneys, the lab is actually checking on the level of creatinine in the urine. A high urinary creatinine level can mean a problem in the muscles, since the muscle cells send the creatinine to the kidneys. It may also mean there is a problem in the kidneys that is, the kidneys are unable to excrete the creatinine.

Is There Any Cure For Kidney Failure In A Cat

Creatinine Levels

There is no cure for kidney failure other than an extremely expensive kidney transplant. While money isn’t an issue, your cat needs to be healthy enough to have surgery, and Hell will also need special meds for the rest of his life.

Heart failure is a chronic disease of the heart in which the heart can not pump enough blood according to the requirements of body tissues. When the supply and demand of oxygen are not in a balance because of low cardiac output, the condition is known as heart failure. The most common causes of heart failure are coronary artery disease, hypertension, arteriosclerosis, myocardial infarction, hypertension, cardiomyopathy, and congenital heart problem.What is the phy

Normal Blood Creatinine Range

Creatinine levels increase with muscle mass. Other factors, such as age, sex, ethnicity, diet, etc., also affect its production .

The normal blood creatinine range is around:

  • Men: 0.6 to 1.2 mg/dL 53 to 106 mol/L
  • Women: 0.5 to 1.1 mg/dL 44 to 97 mol/L

Levels may vary slightly between labs, due to differences in equipment, techniques, and chemicals used.

A normal test doesnt mean that kidney disease is absent. Your doctor will interpret your results in conjunction with your medical history and other test results, such as glomerular filtration rate , blood urea nitrogen , phosphate, calcium, sodium, potassium, and glucose.

What Is A Microalbumin Creatinine Ratio

Microalbumin is a small amount of a protein called albumin. It is normally found in the blood. Creatinine is a normal waste product found in urine. A microalbumin creatinine ratio compares the amount of albumin to the amount of creatinine in your urine.

If there is any albumin in your urine, the amount can vary greatly throughout the day. But creatinine is released as a steady rate. Because of this, your health care provider can more accurately measure the amount of albumin by comparing it to the amount of creatinine in your urine. If albumin is found in your urine, it may mean you have a problem with your kidneys.

Other names: albumin-creatinine ratio urine albumin microalbumin, urine ACR UACR

High Blood Creatinine Levels


As the kidneys become impaired for any reason, they start having troubles filtering out waste products and toxins. As a result, creatinine levels in the blood increase. However, there are also several other factors that can increase creatinine levels.

A high level of creatinine will not cause symptoms on its own. Even if you have above-normal levels you may not notice a change. However, high creatinine is often caused by an underlying disease that affects kidney function, such as kidney disease, diabetes, high blood pressure, or hypothyroidism. In these cases, you will experience the symptoms of the underlying disease/disorder. Work with your doctor to treat any underlying condition.

What Are The Causes Of Elevated Creatinine Level

You may have heard about elevated creatinine levels and wondered what this means. First of all, creatinine, a waste product of muscle activity, is found in the bloodstream. It ends in the kidneys where it is filtered out and excreted in urine. A routine blood test can help determine your creatinine level which reflects your metabolic health. In case you have a higher than normal creatinine level, it could indicate the presence of an underlying condition.

What Are The Stages Of Kidney Disease In Cats

Stage of kidney disease in cats. Kidney disease in cats can be classified based on the level of creatinine in the blood. Values between and mg/dL indicate stage II or mild insufficiency. Values between 5 and 5 mg/dL indicate stage III or moderate deficiency, while values greater than 5 mg/dL indicate stage IV or severe deficiency.

How Is A Creatinine Test Done

There are two main ways doctors use creatinine tests to measure kidney function:

  • Urine tests. Creatinine clearance can be pinpointed by measuring the amount of creatinine in a sample of pee collected over 24 hours. For this method, you store all your urine in a plastic jug for one day and then bring it in for testing. This method is inconvenient, but it may be necessary to diagnose some kidney conditions.

  • Blood tests.Doctors can estimate GFR using a single blood level of creatinine, which they enter into a formula. Different formulas take into account your age, sex, and sometimes weight and ethnicity. The higher the blood creatinine level, the lower the estimated GFR and creatinine clearance.

For practical reasons, the blood test method for GFR is used far more often than the 24-hour urine collection test for creatinine clearance. But urine collections may still be useful in people who have large muscle mass or a marked decrease in muscle mass.

What Level Of Creatinine Indicates Kidney Failure And When To Worry About Creatinine Levels

The normal creatine level is different in males and females. In the female, the normal level of creatinine is 0.6 to 1.1 mg/dl while in male, the level of 0.8 to 1.3 mg/dl is considered normal. The creatinine levels are also affected by race. In non-Hispanic blacks, males have 1.25mg/dl while the female has 1.01 mg/dl as average creatinine level and in non-Hispanic whites, the average level of serum creatinine is 1.16 mg/dl in male and 0.97 mg/dl in the female. The level of creatinine above 2.0 mg/dl in infants and above 5.0 mg/dl in adults indicates severe kidney problems. Now that you are clear with when to worry about creatinine levels.
