crystals in feces

A variety of crystals can be seen in normal feces, such as calcium phosphate, calcium oxalate, cholesterol, calcium carbonate and other crystals, with little clinical significance. See the Charcot-Lyden crystallization, often associated with amoebic dysentery, hookworm disease and other intestinal parasite infections and allergic enteritis; see brown crystal, suggesting bleeding in the digestive tract. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: No or a small amount of crystallization is normal. Positive: A large amount of crystals were detected as positive, and the disease was judged according to the shape of the crystal. Such as: prismatic crystal phosphorus poisoning, intestinal bleeding; bilirubin crystal bacterial dysentery (dysentery), infant feces. Tips: Fresh fecal specimens should be sent in time, and old specimens greatly affect the positive detection rate. Normal value No or a small amount of crystallization. Clinical significance Abnormal results: (1) prismatic crystal phosphorus poisoning, intestinal bleeding. (2) bilirubin crystal bacterial dysentery (dysentery), infant feces. (3) Drug crystallization tincture (diamond, column, granule), iron (unshaped black), barium sulfate (colorless small pieces), charcoal (black small pieces). (4) Charcot-Leyden (Xiaco-Leden) crystalline amoebic dysentery, acute hemorrhagic bad enteritis, intestinal ulcer. Need to check the crowd: Bloody stools, diarrhea, abdominal pain symptoms. Positive results may be diseases: bacterial dysentery, phosphorus poisoning, amoebic dysentery precautions Note when checking: 1. Fresh fecal specimens should be sent in time, and old specimens greatly affect the positive detection rate. 2, must not be mixed with urine, no disinfectant and sewage. Preparation before 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. Not suitable for people: Non-invasive examination, there is no inappropriate population. Inspection process Microscopic examination was performed to find out whether there were prismatic crystals, bilirubin crystals, drug crystals, and Charcot-Ryden crystals in the stool samples. Not suitable for the crowd No taboos. Adverse reactions and risks This test itself does not cause complications and harm.
