LIFECODES LSA Class II

Werfen has identified that two beads within the LIFECODES LSA class II assay kit(s) may present different DQB1 specificities than previously understood:• Bead 42 / Antigen ID 242Previously associated with DQB1*02:01, this bead instead presents DQB1*02:02• Bead 44 / Antigen ID 244Previously associated with DQB1*02:02, this bead instead presents DQB1*02:01• Note: DQA1*02:01 is present on both beads and therefore not impacted.Due to this issue, certain reactivity patterns may appear differently than expected.
