Renal function

Renal function test is an experimental method to study kidney function. Urine microscopy and chemical tests and certain chemical tests of blood are commonly used to measure changes in renal function. Common measurement items include: urine sample, urine specific gravity, urine sediment microscopy, urea nitrogen, creatinine, non-protein nitrogen quantification, and phenol red excretion test. Many environmental pollutants, such as lead, mercury, cadmium, chromium, arsenic, hydrocarbon solvents, petroleum products, etc. can cause kidney damage. Renal function tests are an important indicator.
