Why it was recalled

The barcode orientation on affected devices causes incorrect scanning order of tubes within the allergen holder wedge. When using an IMMULITE 2000 / IMMULITE 2000 XPi instrument in combination with a Zebra barcode scanner, the instrument will not correctly recognize the position of tubes within the allergen holder wedge.
