肌酐（creatinine） creatinine medical aircraft Creatinine (creatinine, Cr) is a product of muscle metabolism in the body, producing 1mg creatinine per 20g of muscle metabolism. Creatinine is excreted mainly by glomerular filtration. Serum creatinine comes from two exogenous and endogenous sources. Exogenous creatinine is the product of meat metabolism in vivo; endogenous creatinine is the product of metabolism of muscle tissue in vivo. When meat food intake is stable, there is no major change in body muscle metabolism, and creatinine production is relatively constant.

Creatinine classification Creatinine is divided into serum creatinine (SCr) and urinary creatinine (UCr), serum creatinine: serum creatinine in normal subjects is 53 - 140 moI / L. Urine creatinine: creatinine derived primarily from blood filtered through the urine after glomerular filtration. [reference value]8.4 - 1 3.25mmol / 24 hr urine or 40 mg/dl to 130 mg/dl is normal. Edit this segment of serum creatinine Clinical examination of serum creatinine is one of the most common methods for understanding renal function. So what happens to creatinine? Endogenous creatinine is a product of muscle metabolism in humans. In muscle, creatine slowly forms creatinine through irreversible non enzymatic dehydration, which is then released into the bloodstream and
