Tonsils are an immune organ of the human body with an important immune function, and often unclear diagnosis and incomplete treatment can lead to recurrent inflammation, which can cause significant damage to the human body. Therefore, in addition to the combination of medical history, symptoms, signs and symptoms used to diagnose, but also need to use auxiliary examination, comprehensive analysis, accurate diagnosis. The following is a list of auxiliary tests for tonsils that have become small and tough. 1, blood image and blood sedimentation blood image in addition to leukocytosis, there may also be lymphocytosis and plasma cells. 2, anti-streptococcal hemolysin “o” reaction Normal people anti-streptococcal “o” content fluctuates within the range of 166-333 u. There are complications anti-streptococcal “o” content, generally high. 3.Immunoglobulin measurement In physiological condition, tonsil mainly produces IgA, and in pathological condition, mainly produces IgG. if IgG is dominant in the interstitial tissue outside the crypt-lymphoid unit within the tonsil tissue, it means that the tonsil has already formed a lesion, which needs to be taken seriously. 4. Measurement of myocardial enzyme spectrum Myocardial enzyme spectrum is high, indicating that myocardial damage is caused by tonsillar inflammation. 5.Urine routine If there is hematuria or a large number of red blood cells or a small amount of protein and tubular pattern, the particles should be tonsillitis combined with nephritis. 6.Electrocardiogram Abnormal electrocardiogram indicates that myocardium is damaged, which indicates that tonsillitis causes cardiac lesions.
