Whenever a screening test (RPR, VDRL) is positive, a more specific test (FTA-ABS, TP-MHA) should be used to confirm the test and rule out a "biologic false positive." The patient has syphilis, but is so early in the course of the disease that the test has not yet turned positive.

Microhemagglutination Assay for Treponema palli-dum Antibodies or MHA-TP test. To better under-stand its potential role in the serologic diagnosis. ABS) test, the standard treponemal antigen test. The VDRL is well standardized, inexpensive, can Medical Association, Atlantic City,June 16,1975.

2024年2月6日 · The largest study of cardiovascular syphilis included 21 patients and found sensitivities of the MHA-TP and FTA-ABS were 89.5% and 100%, respectively (114). The sensitivity of nontreponemal (lipoidal antigen) tests varies from 47% to 64% during tertiary syphilis ( 21 ), whereas treponemal tests remain reactive.

The microhemagglutination assay for T. pallidum (MHA-TP) and T. pallidum hemagglutination assay (TPHA) are manual indirect hemagglutination assays performed in microtiter plates using sheep and fowl erythrocytes sensitized with T. pallidum antigen, respectively, which agglutinate with anti-treponemal IgM and IgG antibodies (2, 10).

2020年6月24日 · Among the 16 treponemal assays reviewed, there were 13 immunoassays and 3 manual assays: fluorescent treponemal antibody absorbed test (FTA-ABS), microhemagglutination assay for Treponema pallidum antibodies (MHA-TP), and TP-PA. Ten treponemal tests had published data on sensitivity and specificity.

梅毒是由苍白螺旋体 感染 引起的一种 性传播 性疾病 。 梅毒螺旋体 感染人体后出现两种抗体：一种是特异性抗体 (TPHA)，为lgM。 当有补体存在和厌氧条件下，对活 螺旋体 的动力有抑制作用，并可将螺旋体杀死或溶解，对机体的再感染有保护作用。 另一类是非特异性抗体（快速血浆反应素 RPR）。 为lgA与lgM的混合物，可与正常生物组织中的类脂 抗原 发生非特异性结合，对人体无保护作用。 梅毒抗体的实验检测有将梅毒的病原体菌体和将菌体成分作为抗原的实验方法， …

2025年3月7日 · Slim attention shrinks the context memory size by 2x for transformer models with MHA (multi-head attention), which can speed up inference by up to 2x for large context windows. Slim attention is an exact, mathematically identical implementation of the standard attention mechanism and therefore does not compromise model accuracy.

A surface immunofluorescence assay (SIFA) using live spirochetes was analyzed and compared with Western blot (WB), fluorescent treponemal antibody absorption (FTA-ABS), microhemagglutination (MHA-TP), and Treponema pallidum immobilization (TPI) assays for detecting serum antibodies to T. pallidum in patients with syphilis, in disease controls ...
