Report 2 of 5.Ortho representative nick gould performed a literature review and requested that this abstract be documented."1.Title: evaluation of the ih-1000? immunohematology gel system for use in a hospital transfusion service.Author/inventor: laufer, melissa j.A.(correspondence); zollman, marianne m.; brown, deanna; madole, mandy; jack, elizabeth; williams, candace corresponding author facility: biorad laboratories inc., carson tahoe regional medical centre, carson city, nv.Source transfusion, (september 2017) vol.57, supp.Supplement 3, pp.141a-142a.Abstract number: cp199.Meeting info: aabb annual meeting 2017.San diego, ca, united states.07 oct 2017-10 oct 2017 issn: 0041-1132.Abstract.Background/case studies: the purpose of this study was to evaluate the performance of the ih-1000? automated blood group analyzer (bio-rad laboratories, inc.) in a transfusion service.The analyzer was compared to their existing platform; the provue? (ortho clinical diagnostics).The facility's objective was to continue utilizing gel technology with a different manufacturer for higher throughput and better efficiency.This hospital facility performs approximately 8k types and screens per year.Study design/methods: edta samples were tested on the ih-1000 with ih-system gel cards for abo/rh (forward and reverse); antibody screening (abs); abo/rh unit confirmation; crossmatch compatibility (igg); antibody identification (abid); and weak d.Anti-igg direct antiglobulin test (dat) was performed on both edta samples and edta cord blood samples.These tests were compared to the provue for concordance.Additional samples tested with anti-igg,-c3d were correlated against tube testing for the data and antigen typing for: c, c, e, e, and k.Results/findings: the ih-1000 had 100% concordance for all blood grouping assays.For ahg assays, the ih-1000 detected an (1) anti-jka+e, (2) anti- fya+warm antibody, (3) antibody to a high incidence antigen and (4) a warm antibody that were missed by the provue.The ih-1000 identified one additional (5) anti-e not identified on the provue.Discrepancies were also noted with the non-cord dat results.Five samples were positive on the ih-1000 with anti- igg,-c3d vs.Tube testing; reflecting the increased sensitivity of gel methodology over tube.Conclusion: this study demonstrated that the ih-1000 analyzer and associated ih-system? gel cards are equivalent to the ortho provue.With random access capability, minimal operator touchpoints, broad test menu and excellent assay performance, the ih-1000 is an ideal immunohematology system for the hospital transfusion service environment.(table presented)." other relevant details: tsc made multiple attempts to contact the customer via phone and email requesting details of the event but no response has been received to date.Contact dates: 4/30,5/1/2018, and 5/7/2018.Call will be reopened if/when customer calls back.
