Blood Vial Recall

Tuesday, June 18, 2019 3:44 PM | Anonymous member (Administrator)

On June 12, the Washington Toxicology Laboratory was notified TriTech had recalled a batch of the blood vials used by law enforcement for investigation of impaired driving crimes.   The notice recalls Lot #8187663.  This batch of vials is packaged into Blood Evidence KitsThese small white boxes have Lot # 43937 printed on the outside and they would all expire on 7/31/2020.  All these evidence collection kits would have been shipped between 11/12/18 and 1/31/2019.                                                   

The recalled blood vials will likely have no impact on cases in Washington for two reasons:  1) the chemicals that might not be present are only necessary for alcohol analysis.  WAC 448-14-020.  That means drug analysis is unaffected.  Since confirmation of drugs is a major reason for seeking blood analysis-a high proportion of the affected cases will be drug cases.  2) the two required chemicals (anti-coagulant and enzyme poison) are mixed together in the correct proportions, then placed into the vials.  That means if we have sufficient anti-coagulant, we also have sufficient enzyme poison.  Deducing if the blood is clotted is very easy--and a regular part of the blood analysis.  If the blood is not clotted, we can be assured sufficient chemicals are in that vial.  Because forensic scientists are routinely questioned about the presence of the chemicals, they always check to verify clotting.  If there were clotting, the analyst would immediately note the anomaly and the report would include that fact.
