IMMUTREP TPHA Ref OD221/OD071/OD081
Treponema pallidum haemagglutination test for the
Serodiagnosis of Syphilis.
Store at 2oC to 8oC. DO NOT FREEZE.
For in-vitro diagnostic use only.
INTRODUCTION AND INTENDED USE
Syphilis is a complex disease which is normally sexually transmitted. The causative organism, Treponema pallidum cannot be grown on conventional laboratory culture media or in the tissue culture. Infection is normally diagnosed by detecting antibodies specific for T. pallidum in the patient’s serum or CSF.
Antibody becomes detectable at about 3-4 weeks following exposure, and may remain at detectable levels for long periods after treatment. Two groups of antibodies are formed: one reacting with the non-treponemal antigens used in the VDRL/Carbon Antigen and RPR tests, and the other reacting with the specific antigens of T.pallidum. Antibody to non-treponemal antigens is found (normally) in active disease and the levels subside after successful treatment. Specific antibody persists long after the infection has been successfully treated. It is necessary to test for both groups of antibody since the non-treponemal antibody may arise for reasons other than Syphilitic infection.
IMMUTREP TPHA is a specific, sensitive passive haemagglutination test for the detection of antibodies to Treponema pallidum in serum or CSF.
For professional use only.
PRINCIPLE OF THE TEST
IMMUTREP TPHA comprises T. pallidum sensitised formolised tanned fowl erythrocytes; unsensitised formalised tanned fowl erythrocytes, diluent and control sera. When diluted positive samples are mixed with sensitised erythrocytes, antibody to the sensitising antigen causes agglutination of the cells. The cells form a characteristic pattern of cells in the bottom of a microtitration plate well. In the absence of antibody, they form a compact button in the well.
This test has been calibrated to WHO Reference Serum for Serodiagnostic tests for Treponemal Infections- Ref 3-1980 +/- one double dilution to ensure the correct sensitivity.
