cysticercoid latex agglutination test

The larvae of swine mites - the cysticercosis of the pigs can cause porcine cysticercosis, commonly known as cysticercosis. Adults with swine mites can also parasitize the human small intestine causing swine tsutsugamushi disease, commonly known as tsutsugamushi disease. There are three main ways of infecting human cysticercosis: 1 allogeneic infections eat food or water contaminated with eggs of locusts; 2 patients infected with mites in their own body eat eggs or segments excreted in their own body; 3 themselves In the case of tsutsugamushi disease, the adult uterus of the intestine is detached from the genital tract. The gastrointestinal tract is reversed (such as nausea and vomiting) into the stomach, and the segment is digested and released to infect the egg. The clinical manifestations of cysticercosis vary depending on the parasite and number of cysticercosis. When the cysticercosis is subcutaneous and muscle, the symptoms are mild or asymptomatic, but if it is parasitic in organs, especially in the brain, eye or central nervous system. , can produce serious clinical symptoms and consequences. Because cysticercosis is parasitic in tissues and organs, it is difficult to obtain material for pathogenic diagnosis, and more immunological methods are used for diagnosis. Currently, the antigens used for diagnosis are mainly cystic crude antigens and purified antigens. The detection methods mainly include IDT, IHA, IFAT, ELISA, ELIB and the like. Basic Information Specialist classification: Infectious disease examination and classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: The positive rate of detection antibody was 81.4%; the positive rate of CAg in patients with cysticercosis by McAb-LAT was 73.05%, and the positive rate at 3 months after effective treatment was 44.11%. Detection of cerebral cysticercosis patients: active period was 97.29%, calcification period was 31.11%; cerebrospinal fluid detection rate was higher than serum. Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. Normal value negative. Clinical significance Abnormal results: The positive rate of detection antibody was 81.4%; the positive rate of CAg in patients with cysticercosis by McAb-LAT was 73.05%, and the positive rate at 3 months after effective treatment was 44.11%. The activity period of patients with cerebral cysticercosis was 97.29%, and the calcification period was 31.11%. The detection rate of cerebrospinal fluid was higher than that of serum. Need to check the crowd: Those with abnormal behavior may be cerebral cysticercosis. Precautions Preparation before inspection: 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should fast, so as not to affect the test of the next day. Requirements for inspection: 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 3. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Not suitable for people: There is no inappropriate crowd. Inspection process Split test tube method and slide method. In the test tube method, the test specimen was first diluted in a test tube with a buffer solution, and then the sensitized latex reagent was added, and the latex agglutination result was observed after the reaction. The slide method is easy to operate. After 1 drop of the test specimen and 1 drop of the sensitized latex reagent are mixed on the slide, the result can be observed by continuously shaking for 2 to 3 minutes. A positive reaction occurs in which large particles are aggregated, and a uniform emulsion is maintained as a negative reaction. Not suitable for the crowd There are no special taboos. Adverse reactions and risks There are no related complications and hazards.
