Syphilis testing uses a screening test (we used an EIA methodology to detect cardiolipin) and a confirmatory test a syphilis linear immunoblot assay LIA.

I emphasize that any test methodologies and testing algorithms can be designed in Medinfo.  This is what I selected during the time I was HMC Doha.

My algorithm specification was:

1. Syphilis Testing:
   1. Syphilis Ab test positive or indeterminate:  do InnoLIA-Syphilis test
      1. InnoLIA-Syphilis test positive:  permanent deferral, refer to Infectious Disease clinic
   2. InnoLIA-Syphilis test borderline or negative:  defer for 1 year, then repeat all syphilis testing.
   3. Repeat Syphilis Testing after 1 Year:
      1. Syphilis antibody testing negative, reenter into donor pool
      2. Syphilis antibody positive or borderline:  do InnoLIA-Syphilis test
         1. InnoLIA-Syphilis test positive:  permanent deferral, refer to Infectious Disease clinic
         2. If InnoLIA-Syphilis borderline or negative:  permanent deferral, syphilis not confirmed

This was translated into Medinfo processes as follows:
