What does it mean when the oil light comes on?   The oil light in a car indicates a lack of oil pressure. Typically this means that your motor oil level is low. It can also indicate a leak--head gasket or a cracked engâ¦ine block are two of the most common sources.
The kidneys maintain the blood creatinine in a normal range. Creatinine has been found to be a fairly reliable indicator of kidney function. Elevated creatinine level 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.
Elevated creatinine levels may be the product of intense exercise, excessive intake of creatine supplements or the ingestion of cooked meat, explain Dr. Antoine C. Abcar and Dr. Manpreet Samra in a study published at PubMed Central. High blood creatinine levels may be a sign of kidney disease, warns WebMD.
