Creatinine (Low, High, Blood Test Results Explained) The creatinine levels in both urine and blood are determined and compared. Normal creatinine clearance for healthy women is 88-128 mL/min. and 97 to 137 mL/min. in males (normal levels may vary slightly between labs). Blood urea nitrogen (BUN) level is another indicator of kidney function.

- The range for a normal test result depends on your age and gender. For adults younger than 40, normal levels are typically in the range of: 107 to 139 mL/min or 1.78 to 2.32 mL/s (SI units) for men. 87 to 107 mL/min or 1.45 to 1.78 mL/s (SI units) for women. Creatinine clearance rates go down as you age.For every decade after age 40, a normal test result is 6.5 mL/min less than the numbers above. For newborns, the normal range is 40 to 65 mL/min. An abnormal creatinine clearance rate may mean you have a problem with your kidneys.Or it may mean a problem somewhere else in your body is affecting blood flow to the kidneys.ealthy kidneys remove creatinine from the blood. It then passes out of your body through urine. The creatinine clearance test usually compares the creatinine level in a 24-hour urine sample with the creatinine level in your blood. This tells your doctor how well your kidneys are working.

- The measurement of creatinine can aid in establishing if any of these products were used. Creatinine production and excretion is directly related to muscle mass and is sex and age dependent. Normal random urine creatinine concentrations range from 40-300 mg/dL in males and 37-250 mg/dL in females. Values as low as 17 mg/dL have been observed in rare instances. Certain physiological conditions such as diabetes may result in consistently dilute urine specimens.

- Urine creatinine (24-hour sample) values can range from 500 to 2000 mg/day. Results depend on your age and amount of lean body mass. Another way of expressing the normal range for test results is: 1  14 to 26 mg per kg of body mass per day for men.  11 to 20 mg per kg of body mass per day for women.

- Then came the third test which showed my creatinine level to be 1.33 mg/dl. Almost to the 1.30 mg/dl mark for my age(36yrs) and other criteria. I came to the conclusion that the reason for my elevated creatinine level was due to the use of creatine. So I jumped back on creatine using the recomended dosages.

- Creatinine clearance is a combination of a urine and blood test. A creatinine clearance test is usually ordered if the serum creatinine level is higher than normal or when a person is starting dialysis. Normal creatinine clearance for men is between 97 to 137 milliliters per minute, and women have a normal clearance of 88 to 128 milliliters per minute.

- The level of creatinine in the blood is a useful guide to kidney function, but GFR (glomerular filtration rate) is a more accurate measure. Blood creatinine can be used to estimate GFR (eGFR) using age, sex, and race, and this is often calculated by computer and reported along with the creatinine blood test.If it isn't but you know the creatinine result, you can use our eGFR calculator. Normal GFR is approximately 100mls/min/1.73m 2.The kidneys filter approximately 100mls/min, or 150 litres per day.f it isn't but you know the creatinine result, you can use our eGFR calculator.

Demystifying chronic kidney disease: Clinical caveats for the family physician 8 ]. Age: Glomerular filtration rate de­clines with age. A rule of thumb is that the GFR stays within the normal range (~100 mL/min) until the age of 40, and then declines at approximately 10 mL/min per decade, so that at age 80, normal GFR is 60 mL/min. rule of thumb is that the GFR stays within the normal range (~100 mL/min) until the age of 40, and then declines at approximately 10 mL/min per decade, so that at age 80, normal GFR is 60 mL/min.

Creatinine Creatinine is a metabolic by-product of muscle metabolism, and normally appears in urine in relatively constant quantities over a 24 hour period with normal liquid intake. Therefore, urine creatinine can be used as an indicator of urine water content or as a marker identifying a specimen as urine. Greater than normal intake of water will increase the urine water content (lowering the creatinine level) consequently diluting the amount of drug in urine. Conversely, a limited intake of water can lead to an abnormally concentrated urine specimen (as occurs with dehydration) resulting in elevated creatinine levels.

How can I lower my creatinine level? Thus, if your kidneys are malfunctioning, blood levels of creatinine will rise. With that said, measuring blood creatinine levels are a good surrogate for kidney function. Typical levels of creatinine in the blood range from 0.6 to 1.2 mg/dl in adult males and 0.5 to 1.1 mg/dl in adult females. Muscular adults may have more creatinine in their blood as a function of muscle mass, while elderly people often have lower levels.

What Is Considered Dangerous High BUN Level If so, you will get the result— the BUN to Creatinine ratio. It is more accurate to judge how well your kidneys are functioning. The normal BUN to Creatinine ratio for anyone over 12 months of age is a 10:1 to 20:1. They are designed to show the levels of kidney dysfunction the patient has. It can also be used as a measuring device to see if a kidney disease treatment is working or if the illness condition is worsening. Tag: High BUN Level.

Renal function The normal range of GFR, adjusted for body surface area, is 100-130 ml/min/1.73m 2 in men and women. In children, GFR measured by inulin clearance is 110 ml/min/1.73m 2 until 2 years of age in both sexes, and then it progressively decreases.ne method of determining GFR from creatinine is to collect urine (usually for 24 hours) to determine the amount of creatinine that was removed from the blood over a given time interval. If one removes 1440 mg in 24 hours, this is equivalent to removing 1 mg/min.

Urine Creatinine Levels Pregnant women may also have low blood creatinine levels. A blood creatinine level above 2.0 mg/dL in children and above 10 mg/dL in adults indicate severe kidney impairment. 1  The normal level of urine creatinine in case of a random test may range between 40 to 300 mg/dL in males and 37 to 250 mg/dL in females.

Creatinine and creatinine clearance blood tests A low GFR or creatinine clearance demonstrates kidney disease. The decline in kidney function can be either acute (sudden, often reversible) or chronic (long-term and irreversible). Repeated GFR or creatinine clearance measurements over time can identify kidney disease as acute or chronic.tage 3: GFR 30-59 (moderate decline in kidney function). Stage 4: GFR 15-29 (severe decline in kidney function). Stage 5: GFR less than 15 (kidney failure, usually requiring dialysis). People over age 60 may have an apparently normal creatinine blood level, but still have a low GFR and creatinine clearance.
