Any derangement in the values signifies the impaired kidney function. 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. 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. A normal BUN-creatinine ratio is based on the normal values for BUN and serum creatinine. 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. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. A high BUN value can mean kidney injury or disease is present. Normal value of creatinine is 0.8 – 1.4mg/dL Females have low creatinine than males because of the muscle mass. A value that isn't in the normal range may still be normal for you. 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. Approximate reference (normal) range: Serum/plasma urea 2.5-7.8 mmol/L Serum.

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. These calculate with BUN Creatinine ratio formula. BUN creatinine ratio normal range is commonly between 10:1 and 20:1, a low BUN to creation level is below 10:1 and high BUN: Cr ratio is the level above 20:1. Kidney :: Prostate :: Urinary Bladder :: Testes BUN (Blood Urea Nitrogen) refers to a natural waste product present in the blood. Home » Patient Info » Genito Urinary System » Kidney » Kidney Function tests In the United States only the nitrogen component of urea is measured (the blood urea nitrogen, i.e., BUN), which is roughly one-half of blood urea.
