Abbott has identified the potential risk of contamination of the primary tube with water from the aliquoter module hydraulic circuit, which could lead to incorrect results.The aps aliquoters current error recovery procedure dispenses the aliquoter volume back into the primary tube in the case of an aqm clot detection error (error code e0e0).If the error is not due to a sample clot, but generated from an aliquoter hardware failure, a portion of the distilled water from the aliquoter module hydraulic circuit may be dispensed into the primary tube leading to sample dilution.This issue can occur when a hardware error creates the clot detection error.There has been no reported patient harm due to this issue.
