Creatine is predominantly found in the skeletal muscle. Rates of creatinine production from creatine vary depending on the muscle mass. Daily production of creatinine is 10–15 mg/kg/day in prepubertal children, 15–20 mg/kg/day in postpubertal females, and 20–25 mg/kg/day in postpubertal ...
METHODS FOR DETERMINING TOTAL BODY SKELETAL MUSCLE MASS The present invention is based on the finding that enrichment of D3-creatinine in a urine sample following oral administration of a single defined dose of D3-creatine can be used to calculate total-body creatine pool size and total body ....
They are simple and reliable measures that can be used in clinical practice and research. Further study is needed to determine actionable threshold values for each measure and clinical utility of testing and intervention. 展开 关键词: frailty muscle mass sarcopenia serum creatinine serum cystatin C ...
In addition, it should be pointed out that other variables, including age, sex, and muscle mass can affect serum creatinine concentration. Generally, the level of creatinine is usually higher among people with high muscle mass compared to those with lower levels of lean body weight because of i...

Creatinine levels vary depending on your muscle mass and size. Women and people assigned female at birth (AFAB) typically have a lower normal range of creatinine levels than men and people assigned male at birth (AMAB). Women/AFAB: 0.6 to 1.1 milligrams/deciliter (53 to 97.2micromoles/liter...
This could be explained by age being a potent predictor of mortality and cardiovascular disease independent of urinary creatinine, muscle mass, and gender. Our study shows that the likelihood of chronic kidney disease in the elderly and in women and the risk of adverse outcomes may be inflated ...
However, urine creatinine is affected by muscle mass as well as urine tonicity, and muscle mass is affected by sex, age, nutritional status, and comorbid medical conditions11,12,13. In other words, urine creatinine concentration may have indirect prognostic information on cardiovascular outcomes and...
But instead the study assumed that Black individuals had higher muscle mass, and thus higher creatinine, than white ones. Ashleen Knutsen, Scientific American, 15 Oct. 2020 Urine and creatinine levels were normal, Dr. Montgomery and his colleagues found, and no signs of rejection were detected...
