Treponema pallidum antigen serum test

The Treponema pallidum antigen serum test uses an active or dead Treponema pallidum or a component thereof for antigen determination of anti-helicobacter antibodies. This test has high sensitivity and specificity and is generally used as a confirmatory test. This test is to detect anti- Treponema pallidum IgG antibody in serum. Even if the patient has enough treatment, it can exist for a long time, even if it does not disappear for a lifetime, and the serum reaction persists positively. Therefore, it cannot be used for observation of curative effect. Basic Information Specialist classification: Infectious disease examination and classification: immunological examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Viral infection. Tips: Prohibit unclean sexual intercourse. Normal value The reaction was negative. Clinical significance Abnormal results: 1 stage syphilis. That is, hard chancre, with an incubation period of 2 to 4 weeks, a dark red hard mass, a shallow ulcer, a cartilage-like hardness, and a swollen peripheral lymph node. 2 second phase syphilis. After 1 to 2 months of primary syphilis, sympathetic rash, rash, pimples, pustular rash, etc. occur in the skin and mucous membranes of the whole body. Mucosal plaques, flat wet phlegm can occur in the mucosa, and the infection is strong. 3 third-phase syphilis. Occurred 2 to 3 years or even 10 years after infection, the skin is a gum-like swelling, and may also involve bone, joint, heart, blood vessels, manifesting aortic inflammation, aortic insufficiency and aortic aneurysm, etc., invading the nerve Spinal cord paralysis, generalized paralysis (paralytic dementia). Congenital syphilis has early congenital syphilis, equivalent to the second day of the day, but heavier. Late congenital syphilis is similar to the acquired day, but few heart, blood vessel and neuropathy occur. Mainly for substantial keratitis, neurological deafness, Hutchinson's teeth (central incisors in the upper incisors, small upper and upper, equal width and width), sabre-shaped humerus and so on. There may be latent syphilis between stages, asymptomatic, and only seropositive. The treatment uses penicillin or erythromycin, tetracycline, and the like. The person in need of examination has the above symptoms. Positive results may be diseases: three stages of syphilis, pediatric yaws, bone and joint syphilis, non-sexual syphilis, syphilis precautions The reaction was negative. Inspection process 1. Fluorescent syphilis spiral antibody absorption test (FTA-ABSTest): This method is a more sensitive and specific spirochete test. 2. Treponema pallidum hemagglutination test (TPHA): high sensitivity and specificity, easy to operate, but not sensitive to primary syphilis as FTA-ABS test. 3. Treponema Pallidum immobilization (TPI): After the addition of the patient's serum (containing antibodies) with Nichol's spirochete (live), the activity of the spirochete can be inhibited with the participation of complement. If ≥50% Treponema pallidum stops moving, it is positive. The test has high specificity and sensitivity, but the equipment requirements are high and the operation is difficult. It is for research use only. Not suitable for the crowd There are no special taboos. Adverse reactions and risks There are no related complications and hazards.
