fecal starch granules

Fecal starch granules, a project of fecal microscopy, can understand digestion and absorption functions and help diagnose digestive diseases. Starch granules are luminescent, colorless granules of varying size, round or elliptical. It is easily seen in the stool of diarrhea patients. 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: Normally small or no starch granules. Positive: A large amount of starch granules turn blue with iodine. 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 No or a small amount is normal. Clinical significance Abnormal results: 1. The amount of starch granules appearing in the feces reflects the digestive and absorbing function of the patient. The presence of starch granules indicates poor digestive dysfunction. 2, chronic pancreatitis, pancreatic insufficiency, starch granules increase, and often accompanied by more fat droplets and muscle fibers. Need to check the crowd: Patients with indigestion, patients with stomach pain, chronic pancreatitis, and patients with pancreatic insufficiency. Positive results may be diseases: functional dyspepsia, precautions for pancreatitis Requirements for 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. To avoid interference with the test results, do not use cotton swabs to dig. 3, the amount of feces collected should not be too small (3 ~ 5 grams) to avoid not enough samples for inspection. Preparation before the test: diet should pay attention to, carbohydrate foods eat less. Not suitable for the crowd: generally no suitable for the crowd. Inspection process 1. Take a little manure for the slide, add 1~2 drops of iodine solution and mix the microscopic examination. The starch granules are dyed blue. If it is partially hydrolyzed to red dextrin, it is brownish red. 2. A small amount can be seen in normal stool. The diarrhea is common in feces. In chronic pancreatitis, pancreatic insufficiency, and carbohydrate indigestion, large amounts of feces can occur. 3. Microscopy method A small amount of fecal mass is taken from different parts of the feces, placed on a glass slide, a small amount of physiological saline is added, mixed with a toothpick and coated into a thin layer. Not suitable for the crowd This test is a non-invasive test, so it is generally not suitable for the population. Adverse reactions and risks This test is a non-invasive test, so the test itself will not cause complications and harm.
