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.
