HIV Test Service in a Blood Center, as a Measure against

Transfusion Transmitted HIV Infection

Objective : We tried to provide an HIV-testing service for blood donors in order to avoid

blood donations from those who were at high risk for HIV infection and came to donate for

the sake of obtaining HIV test results.

Subject and Methods : We investigated the rate of donors who answered a$rmatively to the

HIV-risk question on donor interview form and that of the donors who called back after

donation stating that he/she had HIV-risk behaviors. We tested blood specimens of those

donors who wanted HIV test results at the Sapporo Odori Donation Room and induced them

not to donate. Nucleic acid amplification tests and anti-HIV tests were carried out for those

specimens. Those who showed positive results were to be called and notified.

Results : The rate of donors who a$rmatively answered or made a call-back to the question

of HIV-risk factors gradually increased especially after a uniform donor interview form was

prepared. Initially --2 wanted HIV test results among .,,3,3 prospective donors from April

,*** to March ,**+. Among them 22 were recognized to have an HIV risk factor by

interview, and 13 proceeded to HIV testing. None of them proved to be positive for HIV.

Conclusion : HIV test service in a blood center is feasible, but we could not show the

e#ectiveness, probably because of small population under analysis and the low prevalence rate

of HIV in Sapporo.

Key words : HIV testing service, self-exclusion of blood, window phase infection
