Treponema pallidum haemagglutination test for syphilis. Comparison with TPI and FTA-ABS tests.

Abstract

The Treponema pallidum haemagglutination (TPHA) test, the latest to be developed in the group of specific tests for syphilis, has been described by Tomizawa and Kasamatsu (1966), Rathlev (1967), Tomizawa, Kasamatsu, and Yamaya (1969), and Tringali (1970.) An automated microhaemagglutination technique, the AMHA-Tp test, has been evaluated by Cox, Logan, and Norins (1969) and Logan and Cox (1970). 1967). The TPHA test is easier both to perform and to read than either the TPI or the FTA-ABS. These reasons alone make it attractive as a substitute for the more complicated and initially expensive FTA-ABS test in laboratories where it is desired to carry out a simple specific test for syphilis.
