What Is Open Gallbladder Removal. Open gallbladder removalâor cholecystectomy âis surgery that offers permanent relief to a patient suffering from gallstones and other problems associated with the gallbladder. 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.
Glomerular filtration rate (GFR) indicates how well the kidneys are working. The higher GFR, the better kidneys function. However, once you are tested out low GFR, for example your GFR level is 5ml/min, you must wonder âwhat does low GFR meanâ. Generally, our GFR level ranges between 90 and 120ml/min, but these values may change with age.
