4 ml stock is needed for the standard of 1 mg/ml creatinine if a 4.0 mg/dl creatinine standard is needed to prepare 100 ml of the working standard.
Your muscles produce creatinine as a waste product during routine, everyday action. In a typical state, your kidneys remove creatinine from your blood and excrete it in urine. Creatinine can accumulate in the blood and less creatinine will be excreted in the urine if there is an issue with your kidneys.
A high amount of creatinine in the blood or urine may indicate that the kidneys are not doing a good job of filtering the blood. Although high creatinine levels do not pose a life-threatening hazard, they may be a sign of a major health problem, such as chronic renal disease.
