Treponema pallidum hemagglutination test

The Treponema pallidum hemagglutination test is a specific response to serological detection of syphilis. The syphilis patient is diagnosed by detecting the presence or absence of specific antibodies against the Treponema pallidum antigen in the patient's serum, but it cannot be used as a therapeutic effect. Basic Information Specialist classification: Infectious disease inspection and classification: pathogenic microorganism inspection Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: Normal, not infected with syphilis. Positive: Positive can diagnose syphilis. Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. Normal value negative. Clinical significance Positive can diagnose syphilis. Positive results may be diseases: flowering willow disease, third-stage syphilis, congenital syphilis, syphilis precautions Requirements for inspection: 1. The operation of different kits is different, and the operation and judgment results must be strictly in accordance with the instructions in the kit. 2. The antibodies tested in this test will still exist even if syphilis has been effectively treated. Therefore, the positive result may reflect the current infection, or it may be just an indication of past infection. Therefore, this method should not be used as an evaluation of the efficacy of syphilis. 3. Although the specificity of this test is high, leprosy, infectious mononucleosis and certain connective tissue lesions may also cause BFP. Even healthy people can have less than 1% BFP. The cause is unknown and may be related to the underlying disease. 4. It is still difficult to distinguish syphilis from other pathogenic spirals (such as yase and pinna). Therefore, the diagnosis of syphilis still needs to be combined with clinical symptoms. 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 physical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection; the subject with a history of fainting, please explain in advance, we will make special arrangements. Not suitable for people: There is no inappropriate crowd. Inspection process The syphilis serum test includes: 1 fluorescent spirochete antibody absorption test (FTA-ABS); 2 treponema pallidum hemagglutination test (TPHA); 3 syphilis spirochete brake test (TPI). These tests are highly specific and are mainly used in diagnostic tests. Syphilis serological tests include non-treponema pallidum serological tests and syphilis serological tests. The former is often used for clinical screening and judgment of the effect of treatment, the results can be obtained 1 hour after blood draw, and the cost is also low. The latter is mainly used to determine the test, but it does not determine the therapeutic effect. Once syphilis is present, the test will be lifelong positive. Not suitable for the crowd No taboos. Adverse reactions and risks Generally no complications and harm.
