Creatinine blood test is performed to check kidney function. One of the important parameters used to determine the efficacy of kidney function and to detect symptoms of kidney disease, chronic disease, or other conditions is the results of creatinine blood test.
The results of creatinine blood test show the creatinine levels in the blood and also the creatinine clearance levels from the urine excreted from the system. The amount of urine excreted and the level of creatinine in the blood and urine determined from the results of creatinine blood test help determine the level of kidney function.
One of the primary kidney functions is to clean the blood and remove wastes and impurities from it. As a result, creatinine is removed from the blood through kidney function. Results of creatinine blood test help in determining if this kidney function is being performed properly besides showing symptoms of other kidney disease.
An increased blood creatinine level noted from the results of creatinine blood test is one of the symptoms of kidney diseases, kidney malfunction, kidney stones, improper blood flow to the kidney, and other conditions such as muscular dystrophy, myasthenia gravis, heart failure, acromegaly, and blockage in the urinary tract that causes impaired kidney function.
In conjunction, such conditions that impair kidney function also cause low creatinine clearance the symptoms of which are shown in the results of creatinine blood test. This is because kidney function is impaired causing lesser creatinine to be removed from the blood and excreted via urine.
Low creatinine clearance levels in the urine detected through creatinine blood test is one of the symptoms of chronic liver diseases such as cirrhosis. Alternatively, if the results of creatinine blood test show high creatinine clearance, it could be one of the symptoms of muscle injury, carbon monoxide poisoning, and hypothyroidism. Low creatinine levels in the blood noted in creatinine blood test results could be one of the symptoms of lesser muscle mass, muscular dystrophy, and severe liver disease. A very low level of dietary protein intake could also cause decreased blood creatinine levels in creatinine blood test results.
During pregnancy, more protein is required for fetal development and hence lesser blood creatinine levels and high creatinine clearance levels may be seen in the results of creatinine blood test. If your creatinine blood test results show low blood creatinine level, you could be assured that your kidney function is in good form.
Different labs adopt different standards or ranges for blood creatinine and creatinine clearance levels observed through creatinine blood test results. Your physician should be able to help you understand the results of creatinine blood test and explain if it indicates symptoms of decrease in kidney function.
