The urine chloride test measures the amount of chloride in a certain volume of urine.
After you provide a urine sample, it is tested in the lab. If needed, the health care provider may ask you to collect your urine at home over a period of 24 hours. Your provider will tell you how to do this. Follow instructions exactly so that the results are accurate.
Your provider will ask you to temporarily stop taking any medicines that may affect the test result. Tell your provider about all the medicines you take, including:
DO NOT stop taking any medicine before talking to your provider.
The test involves only normal urination. There is no discomfort.
Your provider may order this test if you have signs of a condition that affects body fluids or acid-base balance.

The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test result.
