GLOMERULAR FILTRATION RATE (GFR)


  • Glomerular filtration rate is one of the medical procedures to check how well the kidney organs are working.

  • Examination of GFR or glomerular filtration rate is also the best medical procedure that doctors do to determine the stage of kidney disease.

  • Kidneys are the main filtering system in the body. This organ has the function of eliminating waste from the body and removing it through urine.

  • To support this function, the kidney organ has a part called the glomerulus that works as a small filter to filter metabolic waste from the bloodstream.

  • If the kidneys are not working well, the glomerulus will not filter optimally. Disturbing the function of this organ can certainly trigger more serious kidney disease.

  • What is the function of the GFR test?

  • This examination will help the doctor find disorders in the kidney organ. This test will estimate how much blood is passing through the glomerulus.

  • The doctor will perform this procedure in a simple way, which is to use the creatinine level through a blood test. Next, the creatinine level is entered into the GFR calculator.

  • The GFR calculator is a mathematical formula to calculate the filtration rate with a number of information, such as creatinine level, age, weight, height, gender, and race.

  • So, it is not rare that this medical procedure is also referred to as an eGFR examination or estimated glomerular filtration rate.
