Mega Kits a new concept in reagent kit design, whereby reagents with proven reliability, packed in instrument-specific vials with barcode identification, are sold in very large kit formats, allowing thousands of tests to be run with a single purchase of reagent at exceptionally low prices. Currently, only expensive tests such as Ferritin, D-Dimer, ASO, CRP and sTfR are shipped in the Mega Kit format for direct placement in Beckman Coulter AU-series and Siemens ADVIA analyzers.
