Electrolytes, Fecal
Also known as: FEC LYTES
Use
The Electrolytes, Fecal test is used to measure the concentration of electrolytes such as sodium, potassium, and chloride in a fecal sample. It helps in diagnosing conditions that affect electrolyte absorption and fluid secretion in the intestines. The information provided by this test can assist in diagnosing chronic diarrhea and other gastrointestinal disorders that affect the balance of electrolytes.
