As creatinine production and therefore excretion are normally constant it follows that creatinine production and excretion are of value in monitoring renal disease and renal dialysis. Serum Creatinine Test 1. Extra-renal excretion of creatinine occurs only when there is severe impairment of renal function. Serum creatinine is often measured along with a test for blood urea levels. This article will introduce to you normal creatinine range. In general, creatinine levels will stay the same if you eat a normal diet. It is a byproduct of muscle function. The serum creatinine level can be used to estimate the serum creatinine level. Since creatinine levels are in proportion to muscle mass, women tend to have lower levels than men. Normal creatinine levels tend to vary with age. What Is Ferritin Blood Test And Why Is It Done? Creatinine can be measured from serum, plasma or urine. This is due to the fact that women generally have less muscle mass than men. Reference Ranges: Serum Normal range in Males (mg/dL) Normal range in Females (mg/dL) 1 – 3 months: 0.2 – 0.75: 0.3 – 0.6: 3 – 6 months: 0.3 – 0.7: 0.3 – 0.6: 6 – 12 months: 0.2 – 0.7: 0.2 – 0.75: 1 – 3 years: 0.2 – 0.8: 0.2 – 0.8: 4 – 10 years: 0.3 – 0.8: 0.35 – 0.75: 11 – 15 years: 0.5 – 1.0: 0.5 – 0.95: 16 – 20 years: 0.6 – 1.2: 0.6 – 1.0: 21 – 30 years: 0.2 – 1.2 what does the result mean?

What does a serum creatinine above normal range mean? A serum creatinine level that would usually be considered normal does not rule out the presence of impaired renal function. Here are the normal … Taking creatine supplements may also increase creatinine. Serum creatinine is an index to monitor renal function while being exposed to nephrotoxic drugs, for acute kidney injury or chronic renal failure or in conditions of shock or dehydration where the renal function seems to be impaired.

Getting creatinine levels to the normal range requires the use of medications as well a healthy diet and lifestyle modifications. Because serum creatinine is inversely correlated with glomerular filtration rate (GFR), when renal function is near normal, absolute changes in serum creatinine reflect larger changes than do similar absolute changes when renal function is poor.
