Duodenal fluid and bile test for parasites

Duodenal fluid and bile parasite testing is an auxiliary test for examining parasites. The duodenal juice and bile were extracted with a duodenal drainage tube and examined by direct smear microscopy. After centrifugation, the sediment was taken for microscopic examination. Can check the Giardia lamblia trophozoites, Clonorchis sinensis eggs, liver-shaped blood-sucking eggs and B. vannamei eggs; acute amebic liver abscess occasionally found large trophozoites in the bile. The method is to use the duodenal drainage tube to extract duodenal juice and bile, such as direct smear microscopy; or after centrifugation, absorb the sediment microscopic examination. Through this examination, the corresponding symptoms can be judged. 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 no parasitic infection. Positive: A positive test value indicates a possible parasitic infection. Tips: Do not take anti-parasitic drugs before inspection, so as not to affect the results. Normal value No human parasites were found to be negative. Clinical significance Abnormal results detected parasites. People who need to be examined have abnormal gastrointestinal tracts. Positive results may be diseases: biliary ascariasis, hepatic hydatidosis, trichomoniasis, liver hydatidosis Contraindications before the test: Do not take anti-parasitic drugs before the test, so as not to affect the results. Requirements for inspection: The doctor carefully operates and carefully observes the results. Inspection process Inspection method: each part of the duodenal drainage can be dropped on the slide glass, and the piece is directly covered for microscopic examination. In order to improve the detection rate, each part of the drainage liquid is diluted and stirred with physiological saline, and then dispensed into a centrifuge tube, centrifuged at 2000 rpm/min for 5-10 minutes, and the sediment smear microscopy is taken. If the drainage fluid is too viscous, it should be digested with 10% NaOH and then centrifuged. The Giardia trophozoites in the drainage are often attached to small pieces of mucus, or the worms are aggregated into flakes. The eggs of the flukes of the liver and the eggs of the ginger are not easily identified, but the former can appear in the bile; the latter is only found in the duodenal juice. Not suitable for the crowd Patients who have taken anti-parasitic drugs and other drugs may be affected by the results of the test, and patients with a history of medications of the above drugs are prohibited. Adverse reactions and risks Risk of infection: If you use an unclean duodenal drainage tube, there is a risk of infection.
