So What is Creatinine?
• Creatinine is a waste product of the major energy metabolite creatine.
• Normal creatinine serum blood levels are:
– 0.6 to 1.2 mg/dl in males (53 to 106 umol/L)
– 0.5 to 1.1 mg/dl in females (44 to 97 umol/L)
• Creatinine is usually found in higher quantities (within the blood) in young adults, and lesser quantities in the elderly.
• Those with one kidney will have higher than “normal” levels of creatinine circulating in their blood (roughly 1.8 mg/dl or 160 umol/L).
• Creatinine can be tested for via a blood sample or via a urine sample. On its own a blood sample is more accurate than a urine sample, though combining them together to form what is called a creatinine clearance test (both blood and urine) is the most accurate test.
• High creatinine levels occur due to any number of diseases that cause the kidneys to shut down, including dehydration, shock, congestive heart failure, and bladder outlet obstruction.
• There are no definitive symptoms that are caused by high creatinine levels, though the following could be possibly linked: fatigued, shortness of breath, feeling dehydrated, and confusion.
