One way to possibly raise low creatinine levels in the urine is to take creatine dietary supplements, advises the American Association for Clinical Chemistry. This may increase blood creatine levels as well.
Creatine is a chemical compound that is created in the liver, according to Lab Tests Online, a service of the American Association for Clinical Chemistry. It eventually moves to the muscles, which use the creatine as a source of energy. Once creatine enters the muscles, some of it is converted to creatinine. Creatine and creatinine work together to help muscles operate efficiently. The amount of both chemicals that the body contains depends primarily on muscle mass, so women generally have lower creatinine levels than men.
Low creatinine levels may simply occur due to aging, a very low-protein diet or pregnancy, according to eMedicineHealth. In some cases, however, it can indicate the presence of conditions such as muscular dystrophy, severe liver disease or kidney disease. When a person has chronic kidney disease or kidney damage, he may possibly be experiencing low creatinine clearance levels.
Creatinine blood levels may be checked by taking a creatinine blood test. The test is usually done to determine how well a person's kidneys are working, according to MedlinePlus, a service of the National Institutes of Health.
