A Complete multiplex solution for blood grouping

The versatility of SirYus-IH offers an easy transfer to existing lab workstations and could replace gel cards in a near future. The SirYus-IH technology’s breakthrough enables automated, fast and low-cost multiplex blood grouping tests

SirYus-IH is an innovative patented multiplex approach using hemagglutination principles. This method allows the complete blood grouping (ABO, D, IAT and RhKhell) using only 4 wells instead of tens. The process will require few microliters of samples with a time to result equivalent to gel cards. 

The SirYus-IH products consist of :


TransfusionTest wells printed with anti-group antibodies for the in-parallel capture of red blood cells
TransfusionReagents required for RBC dilutions and handling


Tests are designed to run on gel cards workstations and enable to multiplex existing tests when using same reagents and consumables.

Key points of SirYus-IH

  • Easy to implement: same process as gel cards
  • Cost reduction: test wells, reagents and wastes are rationalized,
  • Workflow improvement
