Event Description

On (b)(6) 2022, genmark was advised of unexpected negative results for pseudomonas aeruginosa on the eplex bcid-gn panel tested on (b)(6) 2022.On (b)(6) 2022, during communication related to the investigation genmark was advised that patient was deceased.The customer was not able to confirm whether the result of the eplex contributed to the death of the patient and referred to the patient history of liver failure and previous admissions for pseudomonas cholangitis/sepsis.Genmark was advised that the patient had been on 2 grams of iv meropenem every 12 hours for two weeks prior to being admission on (b)(6) 2022 with weakness, fevers, and chills.Background: an initial set of blood culture bottles collected on (b)(6) 2022 was not tested on eplex and showed only stenotrophomonas growing in culture.A second set of blood culture bottles were collected on (b)(6) 2022 and this time stenotrophomonas and pseudomonas were seen in culture.An aliquot from this set of blood culture bottles was tested with the eplex bcid-gn on (b)(6) 2022 where only stenotrophomonas maltophilia was detected.Testing a second aliquot from the same bottle with the eplex bcid-gn again resulted in only stenotrophomonas maltophilia being detected.A third set of blood culture bottles were collected on (b)(6) 2022 and only stenotrophomonas was seen in culture.Data was analyzed per internal procedures and confirmed robust internal controls were generated for both eplex bcid-gn runs suggesting the consumables performed as expected.
