Erroneous EliA test results related to problems with liquid level detection and diluent pipetting in Phadia 250 instruments, and deformed bottles. Investigation showed problems with the liquid level detection in diluent bottle batch JJCA resulting in aspiration of no or too low volumes of liquid from the diluent bottle and from the dilution plate.
During an investigation of instrument logs it was determined that In specific circumstances involving multiple steps, a rack sequencing error may occur. This will result in a mismatch between the sample ID and the test result reported for all subsequent sample racks in that run.
Class I - Dangerous
Customers were not following the labeled assay procedure. This was due to a letter issued to them in 2004 from Phadia GmbH, which indicated that customers could omit the pre-wash step. The omission of the pre-wash step, when combined with a change in material source in kit lot #0067, caused elevated results.
