streptokinase-dnase assay

SK-SD is a method for determining cellular immune function in vivo. This method is simple and easy to perform, and is of great significance for the diagnosis and prevention of infectious diseases, immune dysfunction, and allergic diseases. Basic Information Specialist classification: growth and development check classification: immunological examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: 1, OT, PPD miliary tuberculosis when the reaction is weakened, may also be negative. When a healthy person who is not infected with tuberculosis is vaccinated with BCG, both positive and negative are normal. Malignant tumors, leukemia, viral infectious diseases, deficient cellular immune function defects (T cell system) such as over 70 years old, autoimmune diseases, tuberculosis, and other diseases are weakened. 2, SK-SD, DNCB, KLH, PHA congenital cellular immune deficiency syndrome (T cell system) is usually negative. When malignant tumors, leukemias, autoimmune diseases, connective tissue diseases, etc. occur in the defect of acquired cellular immune function (T cell system), when these skin reactions are weakened, and sarcoma-like cell-free immune deficiency syndrome, these skin reactions are all weakened to many. Positive: 1. Strong positive for OT and PPD tuberculosis. 2, SK-SD, DNCB, PHA strong positive for T lymphocyte function is normal. Tips: Keep a normal mindset. Normal value Negative (-) no redness, induration or induration diameter <5mm; positive (+) redness, induration diameter 5 ~ 14mm; strong positive (2+) redness, induration > 15mm. Clinical significance Abnormal result 1. Raise: (1) Strong positive for TB and PPD tuberculosis. (2) Strong positive for SK-SD, DNCB, and PHA is normal for T lymphocytes. 2, lower: (1) The response of OT and PPD miliary tuberculosis is weakened and may also be negative. When a healthy person who is not infected with tuberculosis is vaccinated with BCG, both positive and negative are normal. Malignant tumors, leukemia, viral infectious diseases, deficient cellular immune function defects (T cell system) such as over 70 years old, autoimmune diseases, tuberculosis, and other diseases are weakened. (2) SK-SD, DNCB, KLH, PHA congenital cellular immune deficiency syndrome (T cell system) is usually negative. When malignant tumors, leukemias, autoimmune diseases, connective tissue diseases, etc. occur in the defect of acquired cellular immune function (T cell system), when these skin reactions are weakened, and sarcoma-like cell-free immune deficiency syndrome, these skin reactions are all weakened to many. Need to check patients with the above symptoms. Positive results may be diseases: negative results of tuberculosis may be diseases: leukemia, malignant tumors Inappropriate people: There are no special people in general. Pre-inspection contraindications: This test can only measure the reactivity after sensitization in the past, and can not determine whether it is sensitized at that time. Requirements for examination: Mainly measure the cellular immune function of the body. If the double-stranded enzyme antigen is injected, if the local redness does not occur, the induration reaction may be due to low cellular immune function, and the subject may not have been infected with streptococcus, a skin test should be performed with multiple antigens at the same time. Inspection process Test materials: blood. Test method: enzyme type determination. Test Category 1: Blood biochemical examination. Test Category 2: Enzyme assay. Not suitable for the crowd no. Adverse reactions and risks no.
