Event Description
|
It was reported that an unspecified bd heparin tube gave erroneous results.The following information was provided by the initial reporter: "heparin green top vacutainer tube showed positive/elevated troponin levels that resulted in an in-patient hospitalization which lasted three days beginning on (b)(6) 2019.After three days and more testing the troponin levels were found to be wnl and not elevated.Event was reported by the lab manager to siemens as it was originally thought to be caused by their dimension chemistry analyzer.Upon further investigation by the lab manager, she now believes the event was related to the vacutainer and not the siemens analyzer.The lab manager did not report this incident to bd.It is unknown if siemens reported incident to bd.The event of high troponin levels occurred ¿about 3 times¿ and was resolved by using a ¿sample insert.¿ they use a sample cup.At the time of this report no further information was available."".

H.6.Investigation: the lot number for this issue could not be provided by the customer.Sample was not returned.To assure high quality specimens, several factors are key.Included, but not limited to this are: proper phlebotomy technique to minimize hemolysis and platelet activation, proper tube fill volume to assure the proper blood-to-additive ration, gentle and thorough mixing, proper centrifugation conditions-g force and time, and storage conditions.A discard tube must be used when using a winged blood collection set for venipuncture in order to fill the blood collection set tubing¿s ¿dead space¿ with blood.It is not necessary to fill the discard tube completely.This step will ensure maintenance of the proper blood-additive-ratio of the specimen.The discard tube should be a non-additive or coagulation tube.Adherence to the recommended specimen handling and processing steps will facilitate acceptable specimen quality and overall performance for reliable analytical outcomes.Evaluation of laboratory instrumentation regarding reproducibility/repeatability may be of value.A review of specimen handling parameters would be of value for this tube type.Attached are our pst¿ techtalk and a publication addressing heparin plasma testing in clinical chemistry.We will continue to monitor for additional complaints and emerging trends.
