Treponema Pallidum Haemagglutination (TPHA)

What Is the TPHA Test?

The Treponema pallidum Hemagglutination Assay (TPHA) is a blood test used to diagnose syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. It is commonly used as a confirmatory test following initial screening methods such as the Rapid Plasma Reagin (RPR) test.

How the TPHA Test Works

During the TPHA test, a sample of the patient's blood is combined with particles coated with T. pallidum antigens. If the patient has antibodies against the bacterium, these antibodies bind to the antigens, causing visible clumping. A positive result confirms the presence of syphilis antibodies in the blood.

Accuracy and Diagnostic Value

The TPHA test is highly sensitive and specific, making it a reliable method for confirming syphilis—even in long-standing infections. It can detect antibodies even when symptoms are no longer present or in cases where the infection has persisted over time.

Importance of Syphilis Testing and Early Treatment

Early diagnosis of syphilis is crucial to avoid complications such as neurological damage, cardiovascular issues, and organ involvement. The infection is treatable with antibiotics, and prompt treatment significantly improves outcomes and prevents further transmission.
