What Causes A High Creatine Level

High Creatinine Levels in urine why?

Creatinine is supposed to be in the urine, it's a waste product. If there's more of it than normal, it probably just means the urine was a bit more concentrated than normal. Remember the lab test only measures the CONCENTRATION of it, not the total amount that is there. Maybe he hadn't drunk as much as usual. Also, since creatinine is a waste product from muscles, he would have higher levels if he is quite a muscly guy. In any case it doesn't mean much at all and is nothing to worry about. (It's only when there is a high level of creatinine in the BLOOD that you have to worry)

What causes high reading of creatinine in the urine [not blood]?

Creatinine concentration is checked during standard urine drug tests. Normal creatinine levels indicate that the test sample is undiluted, whereas low amounts of creatinine in the urine either indicate either a manipulated test or low individual baseline creatinine levels. Test samples that are considered manipulated due to low creatinine aren't tested and the test is sometimes considered failed.
Random urine creatinine levels have no standard reference ranges. They are usually used with other tests to reference levels of other substances measured in the urine. Diuretics, such as coffee and tea, cause more frequent urination, thus potently decreasing creatinine levels. A decrease in muscle mass will also cause a lower reading of creatinine. Men have a normally higher rate of creatinine because they have a higher muscle mass than women. Rhabdomyolosis can be another cause

What are the main causes behind the high creatinine production?

Creatinine is a by-product of creatine and creatine phosphate metabolism in muscles, high creatinine levels is associated with big muscle mass. Body builders may have higher creatinine levels than let say a marathon runner. Elevated creatinine levels in blood, signifies impaired kidney function or kidney disease. As the kidneys become impaired for any reason, the creatinine level in the blood will rise due to poor clearance of creatinine by the kidneys. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys ( CKD, ESRD,Renal failure). Your creatinine level may temporarily increase if you're dehydrated, have a low blood volume, eat a large amount of meat or take certain medications may cause acute kidney injury which is detected by looking at BUN/SCr ratio. The dietary supplement of creatine can have the same effect. A failing heart may also show high creatinine levels because there is low perfusion to the kidneys. Kidneys are responsible for eliminating creatinine.JM
