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