Why do you measure kidney function?
Kidneys are the part of your body’s urinary tract system. In general, urinary tract system consists of two kidneys, such as two tube ureters, which pour off urine from each kidney into the bladder, and the urethra. Urethra is another tube that carries the urine out of the body. However, muscles in urinary tract system help to control the release of urine from the bladder. Kidney controls the quantity and quality of fluids that within your body. Although your body equipped with two kidneys, it can also function with one reasonably healthy kidney, when the other one become damaged or removed. But when your kidney function drops below 25%, extreme health problems occur, such as end stage renal disease (ESRD). So it’s very important to measure kidney function, damages and detect abnormalities in earlier stages.
List of tests to measure kidney function?
Your kidneys remove wastes and excess fluid from the blood. Both blood and urine tests indicates, how well both of your kidneys are working. Doing urine tests, you can identify, how instantly body wastes removed and whether kidney is leaking abnormal amounts of protein, or not. Here some of the tests used to measure kidney function, such as:
- Serum Creatinine
Creatinine is one of the waste product, which comes from the normal wear and tear on muscles of your body. Level of Creatinine in your blood depends upon some factors like age, race and body size. In general, Creatinine level 1.2 for women and greater than 1.4 for men, or may be an early sign, if kidneys are not performing properly. Increase in Creatinine level, kidney disease progresses.
- Glomerular Filtration Rate (GFR)
Glomerular Filtration Rate or GFR used to measure, how well the kidneys are filtering wastes and excess fluid products from your blood. In general, GFR reading below 60 is a sign that your kidneys are not functioning properly. GFR reading below 15 indicates about the treatment for serious kidney failure, like dialysis or a kidney transplant required.
- Blood Urea Nitrogen (BUN)
Blood Urea Nitrogen or BUN performed to measure kidney function. Normal BUN range is between 7 and 20, but when kidney function decreases, there will be rises in BUN level.
Ultrasound performed to search for abnormalities, such as contrast in size or position of the kidneys or for obstructions such as stones or tumors.
- CT Scan
CT scan performed used to detect for structural defects, abnormalities and the presence of obstructions.
