The Oregon State Public Health Laboratory (OSPHL) is making
changes to the HIV testing algorithm that will affect specimen submission
criteria for HIV testing. The OSPHL currently performs HIV testing using a
fourth generation enzyme immunoassay (EIA) test, with confirmation and
differentiation using the Bio-Rad Multispot. Bio-Rad is discontinuing the
Multispot test and replacing it with the Geenius. Therefore, the OSPHL is
implementing the Bio-Rad GeeniusTM HIV 1/2 Supplemental Assay in
place of the Multispot.
