Chloride Urine Level Test (24-hr)
Chloride Urine Test (24-hr)
A chloride urine test measures the chloride level in a 24-hour urine sample. Chloride is an electrolyte that helps to regulate the amount of fluid in the body as well as maintain the body's acid-base balance. The body gets chloride from the salt in the food we eat and excess chloride is eliminated in the urine.
Normally, chloride levels increase and decrease in direct relationship to sodium (salt) levels. Conditions such as dehydration, kidney disease, and hypercortisolism can cause an electrolyte imbalance in the body. This can cause symptoms such as prolonged vomiting, chronic diarrhea, weakness, fatigue, and difficulty breathing. Medication for conditions such as high blood pressure (hypertension), heart failure, and liver or kidney disease can also cause an electrolyte imbalance.
A urine chloride level test is usually ordered along with other electrolytes including Sodium and Potassium. It may also be ordered with blood tests like an Electrolyte Panel or Comprehensive Metabolic Panel (CMP) that measures blood electrolyte levels.
Turnaround for the Chloride urine test is typically 1-2 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
For a 24-hour collection, obtain a specimen container and instructions from the draw site.
Urinate at 8 AM (or 8 PM), and discard the specimen. Then collect all the urine including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM [or 8 PM] the following day. The specimen container must be labeled with the donor's name and date and time collection started and finished.
