What is the difference between creatinine and creatine kinase

These are two different lab tests. Serum creatinine is part of a routine lab report; creatinine clearance is not. Creatinine clearance requires a timed urine sample. All the urine you have passed within a specific time period — usually hours — is saved collected in a container and tested. The result shows how much creatinine has passed through your kidneys into your urine. It helps show how well your kidneys are removing the waste products from your blood.

Almost no tubular reabsorption occurs, so the final creatinine levels in the blood and urine represent, in most situations, the amount filtered at the glomerulus, although the relation is not linear creatine and effects on the kidney after increased intake, muscle concentrations of creatine and creatine phosphate remain raised for several weeks there is a small increase in body weight, due to increased muscle mass and fluid retention within the muscle.

Creatinine is produced in the skeletal muscles and transported through the blood into kidney in order to be excreted from the body. Creatinine has diagnostic uses in determining muscle mass and kidney function. The main difference between creatine and creatinine is that creatine is a naturally occurring amino acid in vertebrates which helps to supply energy to muscles and nerve cells whereas creatinine is a biological waste formed by the metabolism of creatine and excreted from the body in urine.

What is Creatine — Definition, Features, Importance 2. What is Creatinine — Definition, Features, Importance 3. Creatine is an amino acid produced in the human body by the liver, kidney, and pancreas. It is also a naturally-occurring amino acid in animals and fish as well. Creatine is transported into the skeletal muscles through the blood and is stored as creatine phosphate or phosphocreatine.

Phosphocreatine is produced by the action of enzyme, the creatine kinase. Phosphocreatine is converted into ATP during highly intense, short duration exercises like sprinting and weight lifting. Creatine is converted into creatinine by non-enzymatic degradation. The biological half-life of creatine is three hours. Creatine supplements may increase lean muscle mass and enhance athletic performance. The supplements of creatine may also decrease the levels of triglycerides , lowering the risk for heart diseases.

The low creatine amounts in muscles may lead to muscular dystrophy. The conversion of creatine into phosphocreatine in skeletal muscles is shown in figure 1. Figure 1: Conversion of creatine into phosphocreatine. Creatinine is a biological waste product formed by the degradation of creatine in muscle cells.
