- Creatinine is a natural product of muscle breakdown that occurs at a low level in the body. Both BUN and creatinine are filtered by the kidney and excreted in urine. For this reason, BUN and creatinine are used together to measure kidney function. If kidney function begins to decline, BUN and creatinine rise. A normal creatinine depends on muscle mass and age. In general, a normal creatine is 0.5 to 1.2 milligrams per deciliter (mg/dL). A normal BUN is 7 to 20 mg/dL. Remember that different laboratories use different testing equipment, and may have slightly different ranges for normal.

- Creatinine is a chemical waste product in the blood that passes through the kidneys to be filtered and eliminated in urine. The chemical waste is a by-product of normal muscle contractions. Creatinine is made from creatine, a supplier of energy to the muscle.

Creatinine (Low, High, Blood Test Results Explained) Blood urea nitrogen (BUN) level is another indicator of kidney function. Urea is also a metabolic byproduct which can build up if kidney function is impaired. The BUN-to-creatinine ratio generally provides more precise information about kidney function and its possible underlying cause compared with creatinine level alone.

Creatinine Creatinine is a chemical waste product that is released into the blood when muscles contract. When kidney function is normal, creatinine is filtered from the blood through the kidneys. When creatinine levels are high, it can be an indicator of kidney disease.

Blood Urea Nitrogen Blood urea nitrogen to creatinine ratio (BUN:creatinine) A BUN test may be done with a blood creatinine test. The level of creatinine in your blood also tells how well your kidneys are working-a high creatinine level may mean your kidneys are not working properly.

Creatinine Creatinine (/kriˈætᵻnᵻn/ or /kriˈætᵻniːn/; from Greek: κρέας, translit. kreas, lit. 'flesh') is a breakdown product of creatine phosphate in muscle, and is usually produced at a fairly constant rate by the body (depending on muscle mass).

Blood Urea Nitrogen (BUN) BUN and creatinine are the primary tests used to check how well the kidneys are able to filter waste products from your blood. Your healthcare provider may also order a renal panel or electrolyte tests, such as sodium and potassium, or calcium to help understand how your kidneys are functioning. ^ Back to top.

Bun Creatinine Ratio The normal ratio of BUN to creatinine in the blood is between 10 and 20 to 1, more or less, although this normal range varies with age and gender.

What Is the BUN and Creatinine Ratio? Your BUN-to-creatinine ratio allows doctors to monitor your kidney health. The BUN-to-creatinine ratio is a routine lab measurement used by your doctor to assess the function of your kidneys. It is calculated by dividing the serum BUN concentration by the serum creatinine concentration. Various conditions affecting your kidneys will alter this ratio in a predictable manner before you even show symptoms. Therefore, it is a useful ratio when monitoring subtle changes in your kidney health.

- Updated April 19, 2016. Blood urea nitrogen - BUN - is a blood test performed as a marker of kidney function. It is part of the basic metabolic panel done for health screening. It is also used to monitor the progression of kidney failure. BUN is produced by the breakdown of protein and usually cleared from the blood by the kidneys.

Blood Urea Nitrogen (BUN) Occasionally, a health practitioner will look at the ratio between a person's BUN and blood creatinine to help determine what is causing these concentrations to be higher than normal. The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration. It may also be seen with increased protein, from gastrointestinal bleeding, or increased protein in the diet.

Kidney Infection Treatment: The Top 10 Home Remedies If creatinine levels are elevated, there could be a problem with the kidneys. A healthy BUN/creatinine ratio is between 10:1 and 20:1, although men and older people can be higher and still be healthy. The eGFR test looks for signs of kidney damage.

Top 30 Doctor insights on: Bun And Creatinine Levels In Dehydration BUN/Creatinine ratio: Blood urea nitrogen (BUN) is the breakdown of protein excreted via kidney. Creatinine is the muscle breakdown product also excreted by the kidney. BUN and creatinine can be measured by lab tests. Usually the BUN / creatinine ratio has to be over 20 for a patient to be considered dehydrated or in pre renal kidney failure. ...

Creatinine Test How is it used? The creatinine blood test is used to assess kidney function. It is frequently ordered along with a BUN (blood urea nitrogen) test or as part of a basic or comprehensive metabolic panel (BMP or CMP), groups of tests that are performed to evaluate the function of the body's major organs.

Blood Urea Nitrogen (BUN) If the creatinine and BUN tests are found to be abnormal or if someone has an underlying disease that is known to affect the kidneys, such as diabetes or high blood pressure, then creatinine and BUN tests may be used to monitor for kidney dysfunction and the effectiveness of treatment.

BUN-to-creatinine ratio BUN-to-creatinine ratio. In medicine, the BUN-to-creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL). Outside the United States, particularly in Canada and Europe, the truncated term urea is used (though it is still the same blood chemical) and the units are different (mmol/L).

What Is Creatinine? What Is Creatinine? Creatinine is a chemical waste product in the blood that passes through the kidneys to be filtered and eliminated in urine. The chemical waste is a by-product of normal muscle function. The more muscle a person has, the more creatinine they produce. Levels of creatinine in the blood reflect both the amount of muscle a person has and their amount of kidney function.

- Two of the tests analyzed in the BMP are kidney-related. They are called BUN (blood urea nitrogen) and creatinine. The kidneys produce stable amounts of BUN and creatinine depending on the functioning ability of a kidney or the kidneys.
