Any derangement in the values signifies the impaired kidney function. Creatinine is a waste product that comes from the digestion of dietary protein and the normal breakdown of muscle tissue. 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). Albumincreatinine ratio ACR is the preferred. Creatinine normal range 45 -90 umolL This is the most common test used to measure kidney function. Urine calcium Ca unrestricted diet 24-h specimen c. Creatinine is the waste product released when the muscle is put to work. An albumin-to-creatinine ratio test is reported in milligrams of albumin per gram of creatine mgg found in one deciliter of urine. 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. Kidney :: Prostate :: Urinary Bladder :: Testes The creatinine clearance test requires a blood sample and a sample of all the urine collected for 24 hours (24-hour urine sample).įor more information, see the topic Creatinine and Creatinine Clearance.Home » Patient Info » Genito Urinary System » Kidney » Kidney Function tests The amount of kidney damage can be estimated by the amount of decrease in the creatinine clearance value. Women should have 45 to 90 mic/L, which is 0.5 to 1.0. Men should have 60 to 110 micromoles/L, which is 0.7 to 1.2 milligrams/dL. If the kidneys are damaged by pre-eclampsia, the creatinine clearance value decreases because the kidneys are filtering less creatinine out of the blood. A normal blood level of creatinine is different for men and women. A measurement of this amount is called the creatinine clearance value. If the kidneys are not functioning normally, high amounts of creatinine remain in the blood while low amounts are passed out in the urine.ĭuring a normal pregnancy, increased blood volume and kidney function cause an increase in the amount of creatinine filtered out of the blood and passed into the urine. ![]() From the kidneys, creatinine passes out of the body through the urinary tract. The kidneys then filter creatinine from the blood. When muscles use energy, they release a waste product called creatinine into the blood.
