The normal creatinine value for a 14 year old child is 0 to 77 μmol/L. Normal human creatinine values vary with age as well as gender.
The upper limit of creatinine value for normal people under the age of 15 years is 77 μmol/L for both males and females. If the age is >15 years, the serum creatinine concentration is different between males and females, the normal range of serum creatinine concentration in males is from 53 to 106 μmol/L, while the normal range of serum creatinine concentration in females is from 44.2 to 88.4 μmol/L.
With the progress of society, the weight of many children and adolescents is similar to that of adults. If the weight of children and adolescents is found to be greater than 50kg, their measured serum creatinine concentration level is not much different from that of adults, and at this time, as long as it does not exceed the upper limit of the normal value for adults, their creatinine level is still regarded as normal, and there is no need to worry too much about it.
If a 14 year old child is found to have a creatinine level that is not within the normal range, it is recommended that he or she consults a specialist in order to rule out dangerous situations so as not to delay his or her condition.
