Some of the Vacuette CAT Serum Separator Clot Activator tubes were manufactured without gel separator, which could yield erroneous assay results and require the patient to return to the lab for recollection or repeat testing. This may result in delayed diagnosis, cause a delay in clinical decision-making or treatment and in some rare cases, yield incorrect results from less stable parameters.
