What is the cause of VDRL positive?
A positive test result means you may have syphilis. If the test is positive, the next step is to confirm the results with an FTA-ABS test, which is a more specific syphilis test. The VDRL test’s ability to detect syphilis depends on the stage of the disease.
What happens if Tpha positive?
Conclusion. If your test results come out to be positive TPHA disease it is imperative to undergo the complete treatment. The TPHA positive treatment requires you to complete the full antibiotics course even if the symptoms subside. Failing to do so can trigger a relapse.

Can Tpha be false positive?
Biological false positive reactions were shown by 26 of the leprosy sera, of which three or 11·5% were also reactive in the TPHA test. A further four sera in the leprosy group were reactive only in the TPHA test. The possible cause of false reactive TPHA test results is discussed.
Is Tpha positive for life?
However, TPHA – Treponema pallidum hemagglutination assay will remain positive throughout life. Positive TPHA just indicates that you have developed antibodies and immunity against syphilis. It does not indicate infection.

As described, there are two standard screening methods and two alternative confirmatory tests for the laboratory diagnosis of syphilis: VDRL (sensitivity = 86%, specificity = 85%); RPR (sensitivity = 78%, specificity = 85%); TPHA (sensitivity >95%, specificity >99%) and.
Will TPHA become negative after treatment?
The response of the Treponema Pallidum Haemagglutination Assay (TPHA) to treatment was studied in 61 cases of early infectious syphilis. In none of the 55 cases of early syphilis in which the pre-treatment TPHA was positive did the TPHA test become consistently negative after treatment.

The venereal disease research laboratory (VDRL) test is designed to assess whether you have syphilis, a sexually transmitted infection (STI). Syphilis is caused by the bacterium Treponema pallidum. The bacterium infects by penetrating into the lining of the mouth or genital area. The VDRL test doesn’t look for the bacteria that cause syphilis.
