Antibody Screen Wash with De-ionized Water, Software Version 3.1


Biotest AG-Dreieich
Dreieich, Germany


Biotest discovered that in rare instances, antibody screen testing may be washed using de-ionized water (System Liquid) instead of the intended Phosphate Buffered Saline (PBS, Wash Solution). This event will not cause an erroneous patient or control result, however an invalid result will occur due to the hemolysis of the Reagent Red Blood Cells. Customers were provided with instructions to avoid this situation in the notification.
