As I designed this in Medinfo, this is algorithm uses an HIV- /HIV-2 antibody EIA screening test, HIV p24 antigen test, and a confirmatory linear immunoblot assay LIA that can discriminate between type HIV-1 and type HIV-2. If there is an indeterminate result, a repeat test is ordered after 8 weeks. A reentry protocol is also included (1.6.3 below).
- HIV Testing:
- HIV-RNA positive confirmed, regardless of other HIV results: permanent deferral and do HIV-InnoLIA, refer to Infectious Disease clinic
- HIV-RNA borderline: do HIV-InnoLIA
- HIV-InnoLIA positive, regardless of other HIV results: permanent deferral and refer to Infectious Disease clinic
- HIV-InnoLIA indeterminate: repeat all HIV testing after 8 weeks
- HIV Ab positive with negative HIV-RNA and/or borderline/negative HIV-InnoLIA: repeat testing after 8 weeks
- Repeat HIV Testing After 8 Weeks:
- HIV RNA positive and/or HIV-InnoLIA positive, regardless of other HIV results: refer to Infectious Disease clinic
- HIV-InnoLIA and/or HIV antibodies indeterminate: permanent deferral, HIV infection not confirmed
- HIV Ab negative and HIV-RNA negative and HIV-InnoLIA negative: reenter into donor pool
This algorithm is represented in Medinfo as follows:
