Methodology is the systematic, theoretical analysis of the methods applied to a field of study. It comprises the theoretical analysis of the body of methods and principles associated with a branch of knowledge.
Creatinine (/kriËÃ¦táµ»náµ»n/ or /kriËÃ¦táµ»niËn/; from Greek: ÎºÏÎ­Î±Ï, translit. kreas, lit. 'flesh') is a breakdown product of creatine phosphate in muscle, and is usually produced at a fairly constant rate by the body (depending on muscle mass).
The creatinine test is used to measure the amount of creatinine in the blood. Because creatinine is a nonprotein end-product of creatine phosphate, which is used in skeletal muscle contraction, the daily production of creatine, and the following product, creatinine, depends on muscle mass, which fluctuates very little.he creatinine test is used to measure the amount of creatinine in the blood.
