Effects Of High Creatinine Levels
It depends/can vary.: The standard reference ranges for serum creatinine are 0.5 to 1.0 mg/dl (about 45-90 ?mol/l) for women and 0.7 to 1.2 mg/dl (60-110 ?mol/l) for men. These can vary. For example, a bodybuilder can have a creatinine level of 2.0 and be healthy, while an elderly female can have a value of 1.2 and have severe renal disease. ...Read more
Upper limit : Creatinine of 1.2 is the upper limit of normal. More important is for you see your estimated glomerular filtration rate. Creatinine levels depend primarily on renal function, muscle mass and to some extent on state of hydration. You should discuss this result with your doctor at your next visit, . ...Read moreSee 1 more doctor answer
Azotemia: High blood urea nitrogen and creatinine together. Please keep in mind that today's "normal creatinine / normal estimated gfr" make all well-muscled men into instant kidney patients, and that eating a big steak can raise your BUN above the reference range. Common sense and a basic knowledge of biology's central to understanding labs. ...Read more
Kidney function: Creatinine is just one measure of kidney function. "Normal" depends upon your lab so it's best to ask doc for results from lab that include reference range. These days, in the States, we ask our labs to calculate eGFR which gives better assessment of kidney function after taking into account age, gender, weight & ethnicity (https://goo.gl/gPIRhM). Young men w/more muscle tend to have higher Creati ...Read more
I've had a creatinine level of 1.8 and 1.9. Is this considered high? If so, what needs to be done to bring it down?
A bit elevated: An elevated creatinine can mean that the kidneys are working less efficiently to eliminate waste products from your body. This can be especially important if you have diabetes or high blood pressure - the two leading causes of kidney disease. If you have either of these underlying conditions, get them under control asap. Ask your doctor about your "egfr" result - another kidney blood test. ...Read moreSee 2 more doctor answers
Co-tango usually: The BUN is usually 10 times the creatinine. When the creatinine goes up, the BUN goes up similarly to roughly keep this proportion, in most kidney disease states. The notable exception is when the creatinine goes up say by 20% to 1.2, but the BUN goes up *5 to 50. This strongly suggests a pre-renal state, commonly dehydration. Mild elevations of BUN with normal creatinines aren't of concern. ...Read more
