Fecal calcium

The amount of calcium excreted by the feces varies from diet to diet. Infants and young children, children and children are more likely to absorb more calcium during the growth and development period. Fecal calcium assays have been used as part of metabolic balance studies. After the patient has a bowel movement in a specific place, the surface of the stool is taken out using a clean container and sealed for inspection. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Less than 14mmol / 24h is generally normal, excessive reduction is generally seen in the successful treatment of patients with osteomalacia and vitamin D hyperthyroidism with vitamin D, because more calcium is absorbed than normal people, so the fecal calcium is reduced. Normal value: Fecal calcium: 0-14mmol/24h Above normal: More than 14mmol / 24h seen in vitamin D deficiency. Foods such as oats contain high levels of phytic acid and calcium phytate formed in the body is insoluble in water and excreted from the feces. Also seen in high phosphorus diet, kidney disease, fatty sputum and malnutrition syndrome (absorption disorder). negative: Positive: Tips: Please avoid digging the part of the toilet urine and tap water when collecting, and do not place the feces directly on toilet paper or paper towels. Normal value General diet, discharge <14mmol / 24h. Clinical significance Abnormal results: Increased in vitamin D deficiency. Foods such as oats contain high levels of phytic acid and calcium phytate formed in the body is insoluble in water and excreted from the feces. Also seen in high phosphorus diet, kidney disease, fatty sputum and malnutrition syndrome (absorption disorder). The reduction is seen in the successful treatment of patients with osteomalacia and vitamin D hyperthyroidism with vitamin D. Because the calcium absorbed by normal people is more, the fecal calcium is reduced. In patients with low levels of phosphate in food, some Boeck's sarcoma patients have increased calcium absorption, but cortisone treatment can reduce this increase. Need to check the crowd: patients with suspected vitamin D deficiency, suspected high-phosphorus diet, kidney disease, patients with fatty spasms and malnutrition syndrome and patients with abdominal pain. High results may be diseases: vitamin D deficiency, kidney disease, malnutrition precautions Requirements for inspection: 1. Please avoid digging the part of the toilet urine and tap water when collecting, and do not place the feces directly on toilet paper or paper towels. 2. To avoid interference with the test results, do not use cotton swabs to dig. 3. Do not collect too much feces to avoid having enough specimens for inspection. Preparation before inspection: 1. If you need to detect fecal occult blood by chemical method, please avoid eating red meat, liver and spinach, cabbage, broccoli and other foods three days before collection to avoid false positive results. 2. If you use the immunological method to detect fecal occult blood, you do not need to limit the type of diet. 3, because infants and young children are not easy to get a sufficient amount of samples at a time, if you need to collect in separate parts, please temporarily store the samples in the refrigerator to avoid bacterial growth. Unsuitable people: routine inspection, there is no suitable population. Inspection process After the patient has a bowel movement in a specific place, the surface of the stool is taken out using a clean container and sealed for inspection. Not suitable for the crowd This examination is a non-invasive examination, so there is generally no suitable population. Adverse reactions and risks This test is a non-invasive test, so it generally does not cause complications and harm.
