Creatinine Blood Test

Creatinine Blood Test

A Creatinine Blood Test measures the level of creatinine in your blood. Creatinine is a waste material that is made using your muscles. Your kidney filters creatinine from your blood and sends it out of the body in urine. A Creatinine Blood Test is done to see how well your kidneys are working. Each kidney has millions of filter units called nephrons. Patients whose kidneys die can’t through out this material.

Creatinine is one of the substances that your kidneys normally eliminate from the body. Doctors measure the level of creatinine in the blood to check kidney function tests (KFT) or Renal Function tests (RFTs). High levels of creatinine may indicate that your kidney is damaged and not working properly.
