Anal swab test

The anal swab test is an auxiliary test for examining parasites. This method is designed according to the characteristics of female aphids in the skin around the anus of the human body and in the perineal skin, with the characteristics that the mites are discharged from the anus or ruptured during active escape, and the eggs adhere to the skin around the anus. This phase check can be used to determine the corresponding symptoms. Basic Information Specialist classification: Digestive examination classification: pathogenic microbiological examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: A negative test result indicates that the body may not be infected with parasites. Positive: A positive test result indicates that the body has a parasitic infection. Reminder: The inspection is usually carried out after waking up in the morning or after a nap, before going to bed, before taking a bath. If the first check is negative, it can be checked continuously for 2 to 3 days. Normal value No parasite eggs or other pathogens were found to be negative during the examination. Clinical significance Abnormal results detected parasite eggs or other pathogens. People who need to be examined have abnormal gastrointestinal tracts. Positive results may be diseases: tsutsugamushi disease , negative results of tsutsugamushi disease may be diseases: perianal eczema, Escherichia coli gastroenteritis, anal canal cancer, perianal tumor, mixed sputum matters needing attention Contraindications before the test: Do not take anti-parasitic drugs before the test, so as not to affect the results. Requirements for inspection: Generally, after waking up in the morning or after taking a nap, before going to bed, before bathing, if the first check is negative, it can be checked continuously for 2 to 3 days. Commonly used methods are the cotton swab swab method and the transparent tape method. Inspection process 1. Swab swab method: first damp the cotton swab in physiological saline, remove and squeeze out too much salt water, use a cotton swab to wipe around the anus of the subject and the perineal skin, then put the cotton swab into a test tube containing saturated saline or In the penicillin vial, stir well, wash the eggs into the salt water, quickly lift the cotton swab, and then discard the salt water on the inner wall of the test tube. Add saturated brine to the nozzle and check it by saturated brine flotation. You can also put a cotton swab that wipes the perianal skin into a test tube filled with water. After fully soaking, lift the cotton swab and squeeze it out in the tube wall. The test tube is allowed to stand for 10 minutes, or after centrifugation, the liquid is poured off and the sediment is taken for microscopic examination. 2. Scotch tape method: Cut a small section of about 6 cm with a width of 1.0 to 1.8 cm of transparent adhesive tape, and fold it to the rubber surface by about 0.4 cm (easy to open), and then attach it to a clean glass slide. Label one end of the slide and indicate the name or number of the subject. Remove the adhesive tape during the examination, paste the patient's perianal skin with the rubber surface before the morning, then place the adhesive tape on the slide and microscopic examination. If there are more bubbles under the adhesive tape, you can uncover the adhesive tape and add a drop of normal saline or xylene. Cover the adhesive tape and check it.
