What Is Open Gallbladder Removal.

The gallbladder is a small organ located near the liver. It stores bileâwhich is a special fluid produced in the liver.
GFR is a test that helps measure the level at which an individual's kidney is functioning. It is calculated on the basis of factors such as age, gender, race, and blood creatinine. Normal GFR values are between 90 to 120 ml/min. A GRF below 60 ml/min could mean that some kidney damage has occurred.
The test measures how much creatinine is in the blood. This shows how well the kidneys are performing. In a normal healthy person the GFR stays close to the same value all of the time. The test is done by taking blood from a person and sending it to a laboratory. Normal values are between 90ml/min and 110ml/min.
