Chemistry - urine
Urine chemistry is a group of one or more tests done to check the chemical content of a urine sample.
For this test, a clean catch (midstream) urine sample is needed.
Some tests require that you collect all of your urine for 24 hours.
Your health care provider will order certain tests, which will be done on the urine sample in a lab.
For detailed information about how to prepare for the test, how the test will feel, risks with the test, and normal and abnormal values, please see the test your provider ordered:
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your doctor about the meaning of your specific test results.
