Test Catalog

Test ID: SYPHT    
Syphilis Total Antibody with Reflex, Serum

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If the syphilis total antibody result is nonreactive, billing will be captured under SYPNB.


If the syphilis total antibody result is reactive or equivocal, then the rapid plasma reagin (RPR) screen will be performed, and billing will be captured under SYPPB.


If the RPR screen is reactive, then the RPR titer will be performed at an additional charge.


If the RPR screen is nonreactive, then syphilis antibody Treponema pallidum particle agglutination testing will be performed at an additional charge.
