That is at the high end of normal. It also depends on whether you are a female or a male. Females generally have a lower serum creatinine level because they generally have a lower muscle mass than males. Creatinine is a byproduct of the breakdown product of creatine, which is an important part of muscle tissue. It is normal for the body to breakdown muscle as it also builds up muscle to maintain homeostasis. So the 1.4 serum creatinine was a result of a test your doctor gave you to check how your kidneys are functioning, and 1.4 is within a normal range.
