HTLV-I/II Confirmation Panel

Also Known as (Alias) Anti-HTLV-I/II
Indications Confirmatory testing performed on an alternate manufactuer’s assay due to a reactive PRISM-HTLV-I/II result.
Method Avioq HTLV-I/II Microelisa System
Test Information Assay is a qualitative enzyme-linked, immunosorbent assay for the detection of antibodies to Human T-Lymphotropic Virus Type I and/or Human T-Lymphotropic Virus Type II in human serum or plasma.
Additional Test Information Although this assay is offered at Bloodworks as a screening test, when used as part of the confirmatory algorithm, it is performed at a referral laboratory.

Also Known as (Alias) Anti-HTLV-I/II
Indications Confirmatory testing performed (in conjunction with alternate manufactuer’s EIA) due to a reactive PRISM-HTLV-I/II result.
Method Indirect immunofluorescence test method for detection and differentiation of HTLV I and II
Test Information Specimens are screened on both HTLV-I and HTLV-II-infected slides.  A specimen is considered positive if it reacts with both antigens.  Positive specimens can be differentiated as to type by titration on HTLV-I and HTLV-II infected slides with the higher titer indicative of viral type.
Additional Test Information This is a referral test.
