A test that uses gelatin particles sensitized with T. pallidum subsp. pallidum antigens to detect specific antitreponemal antibodies in patient serum is called the __________ test
a. RPR
b. FTA-ABS
c. VDRL
d. TP-PA
D
Specific treponemal serologic tests include the FTA-ABS and the TP-PA tests. The TP-PA test uses gelatin particles sensitized with T. pallidum subsp. pallidum antigens. Serum samples are diluted in a microtiter plate, and sensitized gelatin particles are added. The presence of specific antibody causes the gelatin particles to agglutinate and form a flat mat across the bottom of the microdilution well in which the test is performed.
