It is linked with kidney-related diseases or decreased flow of blood to the kidneys secondary to dehydration or congestive heart failure. If the result is higher than the numbers mentioned, it indicates that there is a high level of BUN in the blood. The value is > 15:1 seen in dehydration and hypotension. The ideal ratio is between 10:1 and 20:1. Prerenal azotemia appears with poor renal perfusion, like hypovolemia and hypotension. Any derangement in the values signifies the impaired kidney function. BUN /Creatinine ratio 10 :1 On normal diet 12 to 16 Optimum adult level 15.5 Interpretations of BUN/creatinine ratio: BUN/Creatinine ratio differentiates between acute and chronic renal disease. The normal value of creatinine in urine is found 500 to 2000 mg/day and may vary with age. Creatinine is filtered by the kidneys and excreted in urine. Urine creatinine: This test measures the amount of creatinine in urine. If the GFR is high then it may indicate chances of kidney failure. The normal value in males is 97 to 137 mL/min and females is 88 to 128mL/min. Reference interval for rectal temperature in healthy confined adult cats (2015) Levy JK, Nutt KR & Tucker SJ Journal of Feline Medicine and Surgery 17 pp950-952 found that for the cats in the study, the normal range was much wider, at 98.1-102.1 F or 36.7-38.9 C. It is also done to estimate the glomerular filtration rate (GFR). Creatinine is the waste product released when the muscle is put to work. Creatinine levels may be decreased slightly in pregnancy.Ĭreatinine clearance: This test determines the kidney functioning and suggests kidney dysfunction or decreased blood flow to kidneys as in congestive heart failure. If the level of creatinine is more than the normal value it indicates kidney conditions such as glomerulonephritis, pyelonephritis, acute tubular necrosis, kidney stones, prostate disease, and complications of diabetes. Normal value of creatinine is 0.8 – 1.4mg/dL Females have low creatinine than males because of the muscle mass. Creatinine is filtered from blood and excreted in urine by the kidneys. Creatinine is a byproduct of creatine produced when muscles are put to use. Decreased concentration of BUN is not common and may occur in cases of malnutrition and severe kidney disease.īlood Creatinine: This test measures the amount of creatinine in blood which signifies the filtering capability of kidneys. Elevated levels suggest impaired kidney function such as acute or chronic kidney disease, decreased blood flow to kidneys as in congestive heart failure and shock.

The normal values of nitrogen in blood urea ranges from 7 to 20mg/dL. Urea is a waste product released from degradation of protein, which is filtered in the blood and excreted in urine by kidneys. Some of the commonly conducted laboratory tests areīlood urea nitrogen (BUN): The BUN test measures the nitrogen content in blood urea. These tests reveal the functioning and abnormalities, if any. Kidney function tests are the tests performed to evaluate kidney functioning.

Rochester (NY): University of Rochester Medical Center c2022. University of Rochester Medical Center.If your creatinine level is above normal range. This includes some antibiotics, antacids, and cholesterol medications. Some medications can increase the level of creatinine on lab tests without actually hurting the kidneys. New York: National Kidney Foundation Inc., c2022. Key takeaways: A high creatinine level on a blood test can be a sign of decreased kidney function or kidney disease.

Having said that, if both creatinine and BUN are normal you do not need to worry about the ratio.
