What is the speed of glomerular filtration?

Glomerular filter speed (GFR) is a test used to measure kidney functions, namely how well the structures call glomeruli, they filter blood. Glomeruli is vital units in the kidneys responsible for removing waste substances from the blood. Glomerular filtration speed test is often performed to help diagnose kidney disease, may indicate that the stage in which the disease is also is also an important test to evaluate the progression of kidney disease in many patients.

The calculation of the glomerular filtration speed is often performed based on the patient's profile and creatinine levels in the blood. The patient's profile includes, among other things, age, gender and weight. Men have a naturally higher level of creatinine in the blood than women, so gender is an important part of the GFR calculation. Age is also a factor, because as the individual reaches the age of about 30 years, the degree of glomerular filtration begins to decrease.

creatinine is a waste product product and is usually cleaned by the kidneys for Ethe limination of the urine. When glomeruli does not work well, creatinine in the blood can accumulate in large quantities. Other non -specific symptoms include symptoms of high creatinine in the blood in the blood. Creatinine levels are determined in the laboratory after extraction of the adequate blood sample in the arm.

GFR is reported in milliliters per minute to 1.73 m ^{2 , which is the average surface area of ​​the adult. The normal value for the glomerular filtration speed is about 120 to 130 ml/min/1.73 m 2 . Values ​​falling below normal speed often indicate the presence of kidney problems. The value of 90 ml/min/1.73 m}

2 or higher may mean increasing the risk for the development of kidney problems. Risk factors include hypertension or high -blooded pressure, diabetes and the history of kidney disease in the family.

6 Symptoms of chronic kidney disease include swelling of the face, hands, legs and abdomen and canE proceed to kidney failure unless it is managed. The levels below 15 ml/min/1.73 m

2

are often dangerous because it signals kidney failure, which requires the treatment of dialysis and renal transplantation.

In addition to glomerular filtration speed, kidney function can also be evaluated using the creatinine clearance test. The creatinine creatinine clearance test measures the blood creatinine levels and a 24 -hour urine sample. The process is usually long and tiring and the result is not accurate compared to the GFR test.
