Treponema pallidum haemagglutination test (TPHA) for the serodiagnosis of Syphilis.
The TPHA test kit is a sensitive passive haemagglutination test specifically designed for the detection of antibodies to Treponema pallidum.
- Rapid: within little over 30 minutes of receiving the test sample or culture
- Simple: ready-to-use reagents
- Easy-to-read results
- Excellent sensitivity: high quality specific antigens used in the test provide excellent sensitivity.
Tanned fowl erythrocytes are coated with specific antigen and suspended in a diluent 1,2,3. When diluted positive samples are mixed with the test suspension, antibody to the sensitising antigen causes agglutination of the cells. The cells form a characteristic pattern in the bottom of a microtitration plate well. In the absence of reacting antibody, the cells form a compact button in the well. Uncoated tanned fowl erythrocytes are used as the control cells.
