Hi, It is important to know how much exactly is your creatinine level and the reference values followed by your laboratory. Creatinine levels must be evaluated in detail and treated at the earliest to avoid complications and potential danger to kidney functions. If your creatinine levels are higher than normal, it may suggest that your kidneys are not filtering the blood as effectively as they should. However, over time, glomerular function rate (kidney filtration rate) can fluctuate, so one abnormal test result does not automatically mean that you have chronic kidney disease. A diagnosis of chronic kidney disease is usually only confirmed if repeated glomerular function rate tests show that your glomerular function rate is consistently lower than normal over the space of three months.
