| Treponema pallidum complement fixation t.’s |
nontreponemal antigen serologic tests for syphilis using complement fixation rather than flocculation as the indicator reaction. Once widely used to confirm positive results of flocculation procedures, they have now been replaced by treponemal antigen tests.

| Treponema pallidum hemagglutination a. |
a treponemal antigen serologic test for syphilis using tanned sheep red blood cells coated with antigen from the Nichol's strain of Treponema pallidum and patient serum absorbed with an extract of Reiter treponemes to remove nonspecific antibodies. It is similar in sensitivity and specificity to the FTA-ABS test except that it is less sensitive in detecting primary syphilis.

| Treponema pallidum immobilization t. |
TPI t.; the first treponemal antigen serologic test for syphilis, introduced in 1949, now little used; live Treponema pallidum is mixed with patient serum and complement and examined microscopically to determine the proportion of treponemes that are immobilized by specific antibodies in the serum.
