Recalls for Automated Pipetting, Diluting And Specimen Processing Workstations For Flow Cytometric Analysis

Sample preparation system designed to automate staining, lysing, cell washing has a software error that causes samples to be dispensed close to or touching tube bottoms, which could dislodge fluid line, result in sample loss, spillage, make instrument inoperable and will lead to unintentional removal of 60-100 microliters from final sample, may lead to incorrect diagnosis or patient management.

Automated pipetting, diluting and specimen processing workstations for flow cytometric analysis device instructions for use list incorrect dead volumes: Cassette Type/List volume/correct volume, B/750/1582 microliters, and E/1300/2093 microliters. Device software does not rock Cassette E, used with 15mmX92mm Sarstedt tubes. May lead to incorrect diagnosis or error in patient management/treatment.

Sysmex was made aware of a report of false results due to carry-over caused by the sporadic omission of the probe wash step during antibody pipetting on the PS-10 Sample Preparation System.

Sample preparation system with software may cause: 1) Multidispense feature enabled with 2-tube assay: Specimen volume dispensed into tube1 at least 3% higher than volume in tube2, or 2) Absolute counts calculated using Trucount Tubes: increased volume in tube1 may result in 20% higher absolute counts in tube 1 than tube 2; could result in additional blood collection, delayed results/patient therapy.

The recalling firm confirmed that BD FACS Sample Prep Assistant (SPA) II and III users may encounter probes with unacceptable wear prior to reaching the 2500 piercings guideline indicated in the Instructions for Use (IFU). When the probe is worn, particles from the rubber cap are more likely to clog the probe, resulting in blocked or inadequate sample dispense.

Insufficient amount of antibody without an error message or alarm

When samples are prepared using the PrepPlus or PrepPlus 2 sample preparation systems and then run on a Flow cytometer, there is an imprecision in the absolute counts on only the first tube in a run.
