Serum creatine measurement is used to monitor supplemental creatine intake in humans and to investigate creatine deficiency syndromes.

More information

Creatine is an amino acid found mainly in the muscles of the body as well as in the brain. Although it can be produced within the body by the liver, pancreas, and kidneys, most people receive creatine through diet (fish and red meat). The body converts creatine into phosphocreatine and stores it in the muscles, where it is used to produce energy. Most people take creatine supplements to improve their athletic performance and increase muscle mass.

Creatine is transported from the sites of synthesis (kidney, liver, pancreas) through the circulatory system to the muscle tissue and brain where it is phosphorylated on phosphocreatine. Phosphocreatine and creatine exchange rapidly during muscle contraction. About 1% to 2% of free creatine in the muscles is converted daily to creatinine.

Serum creatine levels can be significantly increased in amyotrophic lateral sclerosis, dermatomyositis, myasthenia gravis, during hunger, in muscular dystrophies, and in injuries. Creatine synthesis is stimulated by methyltestosterone and can also be increased in hyperthyroidism, diabetic ketoacidosis, and immediately after childbirth.

Important Note

Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. The correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".

Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings, and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.

At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
