Renal function test
Renal Function Test
A Renal Function Test (pronounced: /ˈriːnəl ˈfʌŋkʃən tɛst/) is a group of tests that are used to evaluate how well the kidneys are working. These tests are used to detect any potential kidney disease or kidney damage, and to monitor the effectiveness of treatment for kidney disease or damage.
Etymology
The term "Renal" comes from the Latin word "renes", meaning kidneys. "Function" is derived from the Latin word "functio", meaning performance or execution. "Test" is derived from the Old French word "test", meaning small pot used in alchemy, which metaphorically refers to a process of examination or trial.
Types of Renal Function Tests
There are several types of renal function tests, including:
- Blood Urea Nitrogen (BUN) Test: This test measures the amount of nitrogen in your blood that comes from the waste product urea.
- Serum Creatinine Test: This test measures the level of creatinine in your blood. Creatinine is a waste product that is produced by your muscles and filtered out of your blood by your kidneys.
- Estimated Glomerular Filtration Rate (eGFR): This test estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.
- Urine Tests: These tests measure various components in the urine, such as proteins, to help determine kidney function.
