Fecal chloride

Fecal chloride inspection is a routine for stool routines. Chloride is the most abundant anion in the human body. A 70Kg adult has about 81.7g of chloride, 88% of which is outside the cell. The human body regulates the chloride content of the body through dietary absorption and digestive tract, and the discharge of the kidneys to maintain the normal water and electrolyte balance of the human body. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Tips: Because infants and young children are not easy to get enough samples at a time, if you need to collect them separately, please temporarily store the samples in the refrigerator to avoid bacterial growth. Normal value 2 mmol / 24 h (70 mg / 24 h in terms of chlorine). Clinical significance Abnormal results: The first chlorine in moderate diarrhea is 60mmol. In severe diarrhea, the stool composition is close to the ileal fluid, and the amount of chloride lost per day can reach 500 mmol. Congenital diarrhea is a rare case in which a large amount of liquid feces is born and a large amount of chloride is excreted. Need to check the crowd: Patients with long-term diarrhea. High results may be diseases: chronic diarrhea precautions Preparation before inspection: 1. Please avoid digging the part of the toilet urine and tap water when collecting; do not place the feces directly on toilet paper or paper towel. 2. After the specimen is collected, it should be checked within 1 hour. Otherwise, it may be destroyed due to the influence of PH gel digestive enzymes. 3. Do not collect too much feces to avoid having enough specimens for inspection. Requirements for inspection: Because infants and young children are not easy to get enough samples at a time, if you need to collect them separately, please temporarily store the samples in the refrigerator to avoid bacterial growth. Inspection process Silver nitrate precipitates in the chloride to form silver chloride, and excess silver nitrate reacts with the potassium chromate indicator to form a red tin chromate precipitate indicating that the reaction reaches the end point. Not suitable for the crowd This test is a non-invasive test, so there is no contraindication. Adverse reactions and risks This test is a non-invasive test and the test itself does not present complications and hazards.
