capsular swelling test

The capsular swelling test uses a specific antiserum to specifically bind to the capsular antigen of the corresponding bacteria to form a complex for detecting Streptococcus pneumoniae, Haemophilus influenzae and the like. When the specific antiserum specifically binds to the capsular antigen of the corresponding bacteria to form a complex, the test for significantly increasing the bacterial capsule can be used for the detection of Streptococcus pneumoniae and Haemophilus influenzae. Basic Information Specialist classification: Infectious disease examination and classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: There is no large gap around the cells, which is normal and there is no bacterial infection. Positive: It can be judged that there are Streptococcus pneumoniae and Haemophilus influenzae. Tips: Check your relaxation, you should face it positively and actively cooperate with the inspection. Normal value There was no large gap around the cells and it was negative. Clinical significance Abnormal result In the experiment, a large blank circle around the cells was judged as positive, and a blank control without antiserum was used for comparison to determine the presence of Streptococcus pneumoniae and Haemophilus influenzae. Need to check the crowd People suspected of being infected with Streptococcus pneumoniae and Haemophilus influenzae. Positive results may be diseases: Haemophilus influenzae meningitis, pediatric pneumococcal pneumonia, pneumococcal pneumonia, Haemophilus influenzae infection, pneumococcal meningitis in children, pneumococcal sepsis, Haemophilus influenzae pneumonia Contraindications before examination: Specimen collection should be taken before the use of antibacterial drugs. Requirements for inspection: Check the feelings of relaxation, should face positively, and actively cooperate with the inspection. The bacteria that cause meningitis are relatively delicate, easy to die or autolyze, so they should be sent immediately and treated as soon as possible. It is best to inoculate at the bedside. Inspection process After culturing at 35 ° C for 18-24 hours, take 1 drop of culture and add it to the slide. After the culture, add the drop culture to the slide. After the culture, add 1 drop of ink (or methylene blue or methylene blue). Add anti-serum 1, add ink or methylene blue droplets, add anti-serum, mix and add cover slip, mix and cover the slide, and observe under microscope oil microscope. Not suitable for the crowd No taboos. Adverse reactions and risks No complications.
