Urine chemistry

Chemistry - urine


Urine chemistry is a group of one or more tests done to check the chemical content of a urine sample.

How the Test is Performed


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 doctor will order certain tests, which will be done on the urine sample in a laboratory.
