Product Description
The Biorex Diagnostics TPHA Test is a highly specific indirect haemagglutination assay designed for the detection of antibodies to Treponema pallidum, the causative agent of syphilis. It is a confirmatory serological test that provides reliable and accurate results for diagnosis, screening, blood donor testing, and epidemiological monitoring. The assay is suitable for clinical laboratories, hospitals, blood banks, and research institutions, where precise identification of syphilis antibodies is critical for patient care and public health.
This test operates on the principle of indirect haemagglutination, in which erythrocytes coated with T. pallidum antigens react with antibodies present in patient serum to produce visible agglutination. The inclusion of an absorption step reduces cross-reactivity with non-pathogenic treponemes, ensuring high specificity and minimizing false-positive results. The TPHA Test can be performed manually or with semi-automated systems, providing flexible application in diverse laboratory settings.
Key Features
- High sensitivity and specificity – dependable detection of antibodies to T. pallidum
- Confirmatory testing – verifies positive results from non-treponemal assays such as VDRL
- Clear haemagglutination patterns – facilitates easy and accurate interpretation of results
- Built-in absorption step – reduces cross-reactivity with non-pathogenic treponemal antibodies
- Versatile application – suitable for clinical diagnostics, blood donor screening, public health programs, and research
Benefits
Routine use of the Biorex TPHA Test ensures accurate confirmation of syphilis infection, supporting timely clinical diagnosis, safe blood transfusions, and epidemiological surveillance. Its reliable performance, high specificity, and ease of use streamline laboratory workflows and reduce the risk of erroneous interpretations. The semi-quantitative results allow clinicians and laboratory personnel to monitor antibody levels over time, providing insights into disease progression and treatment efficacy.
By integrating the TPHA Test into standard diagnostic protocols, laboratories can enhance diagnostic confidence, optimize patient care, and maintain robust screening programmes. Its trusted performance and user-friendly format make it an essential tool for hospitals, blood banks, and reference laboratories seeking accurate and confirmatory syphilis testing for routine and high-volume applications.
