tularensis agglutination test

T. serrata is a Gram-negative bacillus and is the causative agent of T. turf. For zoonotic diseases, clinical diagnosis is mainly based on immunological tests. Diagnostic value is available when the patient's serodiagnostic titer is >1:40 or higher. However, after 10 to 15 days, the test should be repeated, and when the titer is significantly increased, it is more diagnostic. Basic Information Specialist classification: Infectious disease inspection and classification: pathogenic microorganism inspection Applicable gender: whether men and women apply fasting: fasting Tips: The patient's serum diagnostic titer >1:40 or more has diagnostic value. Normal value Normal value: 0 to 1:40. Clinical significance >1:40 can be considered as Tularon's disease. Precautions Diagnostic value is available when the patient's serodiagnostic titer is >1:40 or higher. However, after 10 to 15 days, the test should be repeated, and when the titer is significantly increased, it is more diagnostic. Inspection process (1) In 10 small test tubes, the diagnostic serum was diluted with physiological saline, and the last tube was not added with serum, and saline was used as a control. (2) Add a bacterial suspension to each tube and shake well. (3) The tube was placed in a 37 ° C water bath for 4 h and then placed at 4 ° C overnight. (4) The reading result is reached with the highest dilution of serum (the liquid in the tube is semi-clarified, and some of the agglutination blocks sink to the bottom of the tube). The agglutination is the agglutination titer of the bacteria. If the titer is more than half of the original diagnostic serum titer used, it is positive. Not suitable for the crowd Those who do not have an indication for examination should not do this check. Adverse reactions and risks Generally no complications and harm.
